Are you not getting a ton of spam from this form being open to public?

I've had similar ideas but I'd probably make it something easy to remember like myname.com/message and it quizzes the user or various things that only my family would know. Things like the color of the bedsheets, which specific IKEA kallax square the cat loves to hang out in, the location in the kitchen where the rice is stored

I've recently stopped or working on stopping the triple digits driving.

The topic at hand this would be a Twilio thing sending a message like "so and so might be in jail take care of the cat" which is messed up/funny but I do tell them in advance can you be on this list. But at least this phase of my life is over/I have something to look forward to/behave for.

Also, how do you prevent spam?

Sorry, you have been blocked You are unable to access delduca.org

I'm from Germany

I thought a solution might be some type of “check-in” service - especially for employees. Are you OK? How can we reach you? Are you available for work? Do you need assistance? Etc.

Things like slack, teams, etc. can fit the bill so it was not really monetizable.

I even created a generator so people can configure it with their Telegram/Pushover settings and have it generate a static app easy to host on Netlify or Clouflare Pages/Workers.

You forget your phone but how do you access a webpage in an emergency?

If this works for you and your personal use case, then everything is fine. But I see a lot of hurdles along the way here.

I would rather think of something like: If my phone hasen't been moved over an X amount of time (locations based or accelerometer) the phone drops a note to predfined receipients with "My phone hasen't moved in 60 minutes, maybe I forgot it somewhere". You can send a location point, but that is just where the phone is.

At least it would solve the point where you have to do something manually.

No matter what solution you choose you will need to remember something. I have two family members who always answer, so their phone numbers are the only two I know. By dialing them manually now and then I make sure my memory is working.

In the age of AI/voice generators I’ve also told them how I will identify myself. So if being mugged in Kiwiland, and they get a call where I ask them to transfer money they can do so knowing it would only be me making that request as I told them the secret phrase: ”yes, it was me who tipped over the Christmas tree”. Ofcourse not that, but something none of the inner family will ever forget.

Anyone will hopefully lend you a phone if you're in a pinch but I realized that I don't know very numbers to actually call and it's kinda weird to start using email/Whatsapp whatever on a strangers phone compared to asking to visit one site and make one call

The issue is verification - a password seems the most obvious. Something you can remember once your phone is gone.

The other issue from reading comments below - you need to be able to walk up to someone and tell them, "I've lost my phone, do you think I can use your phone briefly." Alternatively, you could walk into a box-store (or library) and use one of their PCs.

Also, a way to get transport quickly would be important - perhaps that is the first thing you do when on another computer.
