Personal safety,
finally rebuilt for real life.
Real-time GPS, live video, trusted contacts, and 24/7 trained human advocates — one platform that works together so you're never alone in a crisis.
ByStander is live on Android.
Free to download — iPhone version coming soon.
A panic button isn't a plan.
Three reasons existing personal-safety tools let people down when it matters most.
An app alone can't save you
Most safety apps just send a notification and hope someone responds. They were never built to coordinate a real emergency — only to log one.
A button alone isn't enough
Wearable panic buttons beep into the void. No video, no context, no human on the other end. By the time someone notices, the moment has already passed.
Your contacts can't be on call 24/7
The people who love you want to help. But they're sleeping, working, on a plane, out of signal. You need a system that works even when they can't.
ByStander is what panic buttons should have been.
Real-time GPS + live video + your trusted circle + a 24/7 advocate — all working together the second you trigger an alert.
We built the safety net we wish existed.
“Every personal-safety tool I tried failed at the same thing: the moment that mattered. ByStander exists because the technology is finally there to do better — and because no one should have to face danger alone. We're not building a button. We're building a response system, with real humans behind it, that's there 24/7. That's the whole mission.”
One platform.
Four layers of protection.
Each layer covers the others. If signal drops, video keeps streaming locally. If contacts can't respond, an advocate is already on the line.
Real-time GPS
The moment something feels off, your live location streams to the people you trust. They see exactly where you are — updated every few seconds — not a stale pin from a hour ago.
Live video streaming
Your camera and microphone capture the moment as it unfolds. Streams are encrypted, time-stamped, and saved. Evidence doesn't depend on memory.
Trusted contacts
Your circle gets the alert before you can finish dialing 911. They see your location, hear what's happening, and can call for help on your behalf if you can't speak.
24/7 trained advocates
The piece no other app has. Real people — trained for de-escalation, medical, and police-encounter scenarios — watch your stream and respond. Even if your contacts can't, an advocate is always there.
“ByStander isn't another app with a panic button. It's the first time I've seen technology, trained humans, and the people you love work together as one system. That's what personal safety has always been missing.”— ByStander User, Chicago IL
