Mwangaza looks and works like a calculator. The moment you're in danger, a silent SOS goes out with your live GPS location and audio — to the people you trust. No one watching your phone will ever know.
Four ideas guide everything in Mwangaza — staying invisible, acting instantly, keeping your data to yourself, and costing next to nothing.
Mwangaza hides in plain sight on your home screen. Open it, and it's a fully working calculator — your safety dashboard is just a secret code away.
The app icon reads "Calculator" and behaves like one — addition, subtraction, percentages, all of it. There's no Mwangaza logo, name, or notification anywhere on the device.
Type your personal secret code on the calculator keypad and press = to slip into your real dashboard — no biometrics, no separate login, nothing for anyone else to notice.
Two silent triggers fire an alert that's impossible to miss on the other end — wherever your contacts are, whatever they're doing.
The moment SOS fires, your contacts' phones wake up with a loud, full-screen alert — like a clock alarm that won't be ignored — showing exactly where you are.
Press + three times quickly on the calculator, hold the floating SOS button, use the lock screen button, or let a missed safe check-in trigger it for you. A 5-second window lets you cancel before anything is sent.
Every alert leaves a trail — for you and for the people protecting you. Nothing is guessed after the fact.
The instant SOS fires, your GPS coordinates and a Google Maps link go straight to your contacts. Your location keeps updating for as long as the alert stays active — every 5 minutes on Standard, every 2 minutes on Premium.
Your dashboard keeps a clear log of every SOS — who sent it, when it was triggered, whether it was resolved or cancelled, and the full timeline in between. When you cancel or resolve an alert, your contacts get a follow-up SMS asking them to check in with you and confirm you're safe.
Premium unlocks a set of tools built for the moments before, during, and after a threat — not just the SOS itself.
Safe check-in lets you set a countdown before you walk somewhere uncertain — leave a note like a route or vehicle plate, and if you don't check back in, Mwangaza triggers SOS automatically. Fake call gives you a believable reason to step away.
Set up once. After that, every step is designed to take seconds and raise zero suspicion.
Everything people ask before they trust an app with their safety.
