I built a hands free emergency app after my mom died alone. It can alert 911 silently without you speaking or touching your phone.

I'm the developer. Posting this here because I want real feedback from people who actually use Android every day, not just a download.

Three days before Christmas in 2022 my mom had a massive heart attack at home by herself. She had no way to call for help. By the time anyone knew, it was too late. That's why I built Safety Net.

Safety Net is a personal safety app for Android that works with your phone and optionally a smartwatch. The main idea is that you shouldn't have to unlock your phone, open an app, and dial 911 when you're scared, hurt, or in a situation where drawing attention to yourself could make things worse.

You can trigger an emergency hands free with a voice keyword, a gesture, or a physical button depending on how you set it up. When it goes off, it sends 911 your location and the type of emergency without you having to get on a phone call and talk to a dispatcher. For things like a break in, domestic violence, or any situation where speaking out loud isn't safe, that silent dispatch piece is the part I'm most focused on getting right.

It also monitors heart rate through a smartwatch and can act if it detects something dangerous, alerts your emergency contacts with your location, and has family monitoring so one account can cover parents, kids, or whoever you add.

The app is live on Google Play now with a 7 day free trial on single and family plans.

A few things I'm still wrestling with on Android specifically and would honestly love input on:

Background reliability on Samsung and Xiaomi has been the hardest part. Even with foreground service and battery optimization prompts, some OEMs still kill the app aggressively. If you've built or used anything that needs to stay alive in the background for safety or health, I'd love to hear what actually worked for you.

Wear OS heart rate integration and how much people trust automatic triggers vs manual ones.

How to explain permissions without scaring people off. Location, microphone for the keyword, notifications, background activity. People understand why a safety app needs them but the Play Store flow still makes a lot of folks nervous.

I'm going to be in this thread answering questions. If you try it and something breaks or feels wrong on your device, tell me. That's the kind of feedback I need most.
