- > For most of that period, the size of the Gmail app hovered around 12 MB, with a sudden jump to more than 200 MB near the start of 2017... The Gmail app, on the App Store, is currently 760.7 MB in size.
With charts:
https://www.axios.com/2017/12/15/the-top-iphone-apps-are-tak...
I had no idea common apps used to be just 10-30 MB. But are now hundreds of MB.
Something like Gmail doesn't have massive hi-resolution bitmap graphics. Since the article doesn't give any answer, I'm assuming it's a hand-wavy "frameworks", but that's an enormous amount of compiled code.
- A significant portion of larger sizes is likely due to how Google handles shared code across its iOS suite. They rely heavily on a shared C++ backend (using tools like J2ObjC or similar internal transpilers) to keep logic consistent between Android, iOS and of course the web.
When you pull in the gmail dependency from the internal monorepo, you are most likely pulling in the entire visual stack for Google meet, chat and spaces, plus the heavy protocol buffer definitions and gRPC libraries that underpin them.
Even if you don't use the "meet" tab, the binary could be including the video codecs, the real-time transmission logic plus the AR filter assets, because the app is compiled as a "Super App" container rather than a modular mail client. I feel it's an organizational artifact as much as a technical one.
- The table at the end is seriously misguided. You can’t compare the sizes of an iOS preinstalled app against a non-preinstalled app. It’s just a thin UI shell where the code for all the functionality is inside system frameworks. The Photos app is quoted at 4.2MB. Guess what, if you delete that, you still have system components to render photos, UI for a photo picker, perform analysis on photos such as face recognition, all the iCloud networking code to support iCloud Photo Library, etc.

- > why is the Gmail app almost 80x the size of the native Mail app?
Apple Mail leverages libraries and frameworks already present on the device.
Google uses libraries and frameworks very likely already present on say Android, but on iOS they have to ship a gigantic runtime that implements those things the app depends on; this way they only have to write the app once for several supported platforms.
I’m just speculating by the way but it sounds like the likely reason.
You’ll notice Google Docs or sheets are equally gigantic because each also ships a copy of those enormous runtimes.

- Well, something fishy is going on because there is literally no way that Safari, in its entirety, is 5.1 MB. The numbers for the others app seem similarly off.
It would be really hard to believe that somehow Apple has found some magic formula to make their apps 100x smaller than Google and Microsoft.
Much more likely is that the reporting by the OS is off somehow (probably most of the app functionality is tied up in shared resources counted towards system files, and not counted towards the app's size).
With respect, I would expect more from articles posted on Hacker News. More thorough research, and in fact an answer to the question.

- The article compares the native (iOS) mail app which is (from the article) 8.7MB. What I believe is happening is that the gmail app is not a native app, it is some cross-platform monstrosity, so Google has to bring all the widgets and doo-dads that they wrote so that it looks just like it does on all the other platforms. The native iOS mail app is so tiny because part of iOS that the article mentions taking up 25GB contains all the native widgets and doo-dads that the native mail app can use.
- It’s wild when you put it into context. I remember when Gmail first opened to the public with a whopping *1 GB* of storage… now the app alone almost exceeds that.

- On Android vs iOS, it's worth noting Android apps are smaller than iOS apps. The details are complicated but this report says after installation Android apps take up about half the space as iOS. https://www.safetydetectives.com/blog/app-storage-usage-rese...
One specific complication: Apple's store reports install size, Google Play reports compressed download size. https://www.emergetools.com/blog/posts/are-android-apps-real...

- AOT overhead 200MB (ensuring app loads fast)
Frameworks 150MB
Assets for all screen resolutions 50MB
Google Meet/Chat/etc 100MB
AI models 25MB
- I genuinely struggle to understand how apps can get that large. Games with hi-res graphics, sure. But Gmail barely has any assets. And they aren't shipping with custom runtimes or anything of that sort (like an Electron app) because Apple doesn't allow it. So how much code can you possibly write that compiles to 700 MB?

- I'm assuming one reason is frameworks. They can get quite big.
Another reason, is rusty code (not Rust. It's a play on the saying "Code doesn't rust", which I used to hear, last century).
It does, indeed, rust. Actually, "rots" is probably more apropos.
I'll bet that's the reason that Xcode is such a pig (makes GMail look like an anorexic).
Code is created that people no longer understand, so they are loath to make large changes. They just do enough to fix a bug, and pray that they don't need to dig any deeper. One of my first software jobs, was exactly like that.
When that happens, the code never shrinks. It just accretes.
- The easy answer: Google simply does not care. Some mix of: they don't measure it, they don't look at it, they don't goal around reducing it, nobody's performance review is going to be better because they reduced it, no director is asking product teams why they're increasing the app size. It's not surprising why these companies don't care, because it's a tragedy of the commons. The better question is why is Apple allowing these companies to ship apps that unnecessarily take up a meaningful amount of storage space?
- It might have to do with the fact that (at least on iOS), you can participate in a Google Meet call with just the Gmail app, as well as authenticate sign-ins, and who know what more.
Could the main issue be Google is shipping apps within apps?
- Mine is not 200MB on Android - the base apk is 67MB + 32MB for the ARM v8a specific libs. This is the code, the local caching and other data might make up the rest.
For Android, you can check [1] Download the apk, rename it as a zip and look inside to see the files.
A quick file analysis of the 67MB shows around 58MB of java code and some 32MB of ARM libs, 31MB of this is the libvideochat.
[1] https://www.apkmirror.com/apk/google-inc/gmail/gmail-2025-11...
- I’ve noticed most popular apps are pushing 500+MB. Most likely they are shipping debug builds, with loads of third party deps, so they can send crash reports from production with meaningful stack traces.
Until Apple penalizes app developers for app size, nothing will happen. Most consumers are not aware of the impact , until they go to clean up their phone.
There isn’t much usable free space on the device after the OS, and now having 50+gb of used space from apps, means your own content (photos, music, videos) doesn’t fit.
There isn’t much incentive regardless, since Apple merchandise’s iCloud storage. Bloated apps actually drive iCloud sales. A lose-lose for the consumer.
- The question why is almost all modern apps pushing around 1G.
It is dependencies, if you ever compiled almost any GUI application via prots/pkgsrc on a BSD, you will be shocked by the dependencies that application needs, it is obscene.

- The Facebook and Instagram iOS apps were/are enormous codebases. Absurd, sprawling monsters with tons of dead code, duplication, and old stuff.. like being written in mostly Objective-C.
I imagine the Gmail app also suffers from having zillions of engineers touch it without being incentivized to make it better or smaller, only to add features and impact for the all-important performance review.
Add zillions of instrumentation and third-party frameworks, each with piles of dependencies, and apps will grow without bounds like molecules of gas to fill the container.
- I believe it is because it includes a suite of enterprise management features in addition to Gmail-related features. (Search for "google basic mobile device management" for more info.)
- One of the reasons the Facebook app was large was that they were using Thrift or something and generating a tremendous amount of code for their API interop. Protobuf+GRPC is similarly heavyweight, so I wouldn't be surprised if some megabytes were dedicated to the generated code. But hundreds of megabytes is wild. It has to be one-package compatibility as opposed to specialized app packages for different form factors etc.
- People need to reread this classic piece from 2001 every so often: https://www.joelonsoftware.com/2001/03/23/strategy-letter-iv...
As a regular user, you are probably using 10% of all features available.

- I know that in some cases, apparent bloat like this is related to needing to support so many potential devices and versions of the underlying OS. Google has to support, on iOS, roughly 6 years of devices and their variations + OS variations on them. Each of these may require their own libraries compiled against it, for optimal performance or because it simply is less practical to engineer non-breaking updates against new SDK and HW versions in the same codebase without introducing complexity.
Apple, on the other hand, doesn't have to do this. They can integrate at lower levels and even with all else being equal can develop updates with perfect insight on the ecosystem and foresight on things to come.
Somewhat supporting this possible explanation is that, similar to Apple on iOS, Google's apps on android are significantly smaller.

- Google and others are putting 2FA notifications in their regular apps like gmail. I had to open my gmail app to get a 2FA code instead of my google authenticator app today... which is very weird and probably increases the needed security of the gmail app in addition to the size
- maybe because we need to be pushed to buy minimum the 256GB versions of phones.
it is a wintel deja vu
- I’m surprised so few comments have pointed out how this doesn’t matter at all to anybody. The “apps are too bloated” debate is a dessicated horse.
1. You don’t even have to use the Gmail app to use Gmail. Pick whatever flavor of client you want, they all support Gmail. Apple Mail, Outlook, or something else entirely.
2. If you buy the shittiest available new iPhone it has 128GB of storage. Used iPhone 15 on Swappa with 512GB is <$500. How many of you need hundreds of apps installed on your phone?
3. Nobody’s forcing you to use Gmail. Email is an open federated standard. Use something else.
- I maintain an app size inspection tool that runs locally on your macOS and added the file inspector (Sunburst chart) for Gmail if anyone is interested in exploring its contents.
As others have pointed out, the main executable is huge (~300MB) and there are a lot of localization files, but not too much traditional asset duplication.
You can click into different slices of the app and see what it's made of if interested: https://dotipa.app/?app=Gmail#examples
- For me, the most important takeaway from the article was that the Passwords app supports 2FA codes! I was not aware of this, that's nice and getting rid of Authenticator is one less Google thing to worry about.
- The real reason is Google has no incentive to make it smaller. In fact there is incentive to make it bigger. If your phone runs out of space you need to get a new phone with more memory, or move pictures and the like to the cloud, both of which are good news for Google. So why spend any effort keeping the size down.
- Incidentally, the last ssd i bought at the beginning of last year now costs double what i paid for it.
Ram is what, 3-4x?
It's a great time to ship more bloated apps, the suckers will enrich the hardware manufacturers, won't they?
- Until someone stops installing gmail because it's too big (and it's coming back as a signal), I doubt anything will be done about it. In the absence of constraints, things just keep growing... without constraints. The costs of pruning/shaking embedded frameworks, refactoring, optimization, etc. cannot be justified if it's not signaled as a problem by customers.
- This is why I use installable PWAs wherever possible. On my Android phone right now, the Outlook PWA uses 281kB. You still get notifications, but I haven't measured if data usage is higher.
- Maybe, just maybe should Apple vary the amount they charge by app size.
- > Also, can someone explain why Microsoft Authenticator is 150 MB to show 6-digit codes?
That one's on the author. Duo Mobile is 2MB and shows the same 6-digit codes just fine.
- Software has gotten out of control. A simple Gmail client is now larger than an entire operating system was just a few years ago. And their “web apps” like Google Cloud Console, are so slow that they’re practically unusable in Firefox. Pinnacle of software engineering at Google :/

- 1.15 GB for me - dear god.
There's a comment in the article with two helpful links:
https://news.ycombinator.com/item?id=30443570
https://www.emergetools.com/app/example/ios/com.google.Gmail
The bloat? Mostly "localization".
- For perspective, the entire iPhone OS 1.0.x ipsw image was around 100MB in 2007 (and there was a 4GB iPhone SKU for a brief period.)
- My guess: phone get more storage so we can build fatter apps. With RAM and storage getting more expensive maybe developers will face some pressure to deliver slimmer apps but I don't have many hopes for that. It's going to take at least a couple of device replacement cycles with lower and lower RAM and storage for that to happen.
- I just looked at Gmail on my Android phone and it is only 164 MB. That is a big difference.
Also, one thing that annoyed me when I used iPhones is that you can't remove an app's cache without reinstalling it and losing all your data. And most modern applications think cache is free so they use a lot of it. Many times it will exceed even your installed apps or data size.
- I haven’t made iPhone apps but my guess it that the size comes from bundling libraries and dependencies needed, sort of like how venv includes as snapshot of python and all dependencies into your project folder. Apple core apps probably uses iOS libraries (25GB) already on the device

- Of course it's self-hosted intelligence gathering or metadata auditing. This is Google we're talking about. They're "pushing compute to the edge," taking advantage of more powerful mobile processors to reduce their own infrastructure cost while still providing that sweet sweet Big Data, as they used to call it.

- Android seems to be a bit better in that regard: not in the sense that applications are smaller (though I think they are, slightly), but rather that you can easily unpack or decompile most of them and see what's inside.
There it tends to be mostly due to dependencies, including some native libraries in multiple copies for 2-3 CPU architecture.

- I’m just guessing but probably because it’s not just GMail, it’s likely chock full of all Google’s other walled garden nonsense. Hey, you installed GMail? Great, here’s a 2FA client for all federated Google logins everywhere too. hell i’m surprised it doesn’t contain the entire chrome browser as well.
- If you're interested in iOS app size analysis, I build and maintain this https://apps.apple.com/us/app/dotipa/id6742254881 ($4.99). Happy to share download codes, HMU at info [at] dotipa.app
- Maybe because it’s an Electron app?
Sure, Electron does not come natively for iOS. But with tools like Capacitor, you can take a web app (even an Electron one) and package it for iOS/Android, adding native features and running in a native WebView, allowing it to be an “Electron for Mobile”.

- Size should be a product metric so that it is tracked and optimized. Same goes for memory consumption. It's easy for product to come up with features and run the enxt cool experiment but your users don't care about any of that.

- Android is slightly less horrendous but still bad - probably because at least in some markets enough people have low end phones that size does somewhat matter. I suspect Uber made optimizing app size a priority once they realized that their 1 GB behemoth was hovering on the top of the "things you can delete instead of your wedding photos if you want to be able to continue to use your phone" list, and they were losing customers over it. But there are still apps that are hundreds of MB with no valid reason to be that fat.
Meanwhile, well-written browsers - which are essentially whole operating systems - are in the dozens, so this is 100% bloat.
There simply is little incentive to optimize apps for size, because someone else pays the price and there is little consequence for making it big. Slapping another data collection or ad SDK into the app is easy and free.
If the EU was serious about it, it would consider it part of the ecodesign rules since it forces people to buy new phones for more storage much earlier than needed.
If the app stores were serious about it, they'd either re-introduce the hard cap and stick to it, or at least show the size prominently. Or start charging fees for bloaty apps. At least on the mobile version of the Play store, I don't think you can even see the app size without starting an install - let alone search or filter by it. It's as if they want to encourage bloat.

- Because most phones have enough memory to handle all the bloat, and when they don't, Google can sell those people cloud space. Not to mention that adding more memory is how phone manufacturers earn money - out of my ass example just to illustrate the concept: 100GB phone costs $400, same phone but with 200GB memory costs $500, 100GB memory chip costs $20, manufacturer pockets the difference. Having bloated apps and no SD card (iOS doesn't support SD Cards, Android makes them work like shit on purpose) justifies in the eye of the consumer the necessity of extra memory. Most people have fast internet connection so download time is always acceptably small, no matter how much bloat you put, not to mention that updates are in the background anyway.
The economic pressure to keep apps small is literally negative.
- Why are such apps needed at all? The point of open standards like IMAP is precisely to avoid the need for multiple clients.

- It does do a lot of auth / security stuff for the entire Google Account... not 700 MB worth, but still thinking of the Gmail app as "just an email app" doesn't do it justice either.
- even though I have more data than I ever use on my plan, after 15yr's exclusivly on mobile data, I reflexivly look at the size of anything before I download something, 700mb is bonkers for email, and I have started to reject many other apps, based on there improbable sizes.
useing android my phone has gmail iremovably installed on my phone, but was disabled before I even put a sim in it, but in spite of this, having just checked, it has user data, something in cache, and has used some internet data.

- Not surprising, sadly. In 2022, a friend who did trekking, asked how to view files with national parks borders on a map. I recommended installing QGIS desktop (geospatial viewer/editor of files/database tables). He replied: "1 GB of download?! Seriously?!" I was surprised, because last time I had paid attention, maybe in 2016, it was ~200 megs. I checked, and indeed, it weighed 1 gig. I checked in 2025, and it's beyond 1,3 gig now. And it's FOSS, not commercial bloatware you might think. I have no idea what they stuff it with.
Just yesterday, I wanted to generate a GeoTiff on a macbook. To do it in a simple way, you need libGDAL, a geo-spatial abstraction library that exists since maybe the '90 and supports all thinkable formats. Under Linux, you just install it together with QGIS as a dependency. Mac is still unix, so you may think, a 3-decades old library, with few patches to support modern formats, should be just a couple of megs, right? Brew suggested downloading ~2 GB of ~100 packages!!!! Half of them were aws-* (yes, AWS tools), and 1 GB of LLVM!!! (is it their whole GIT repo with 10M SLOC?)
For geotiff, I ended just using standard Tiff library, inserting my 4 geospatial tags with a few lines of code.

(700 MB more is also an acceptable increase for this feature)
On second thought, I love looking at on-duty page emails in the middle of the night with 7 million lumens blasting my retinas.

- Hacker News is currently sitting at 130 MB. I simply do not understand how these things are calculated but I suspect the calculated amount that the Chrome tab diagnostic isn't a consistent way of comparing to other application memory usages, or at least a mental model that makes sense to most people (e.g. whats a lot of memory consumption? what should it be? is it too high, is it too low? etc.)

- >Gmail isn’t even the worst offender, it’s just a more popular one. The Tesla and Crypto.com apps are around 1 GB each.
One reason is those are typically apps which need to be heavily secured. So behind the seemingly "simple" user interface and functionalities, there's so much security related code to ensure their "safety".
More importantly, it's difficult to code without dependencies.
