Download the Mahsa Alert app
Mahsa Alert is available four ways: an iOS app, an Android app, an installable web app (PWA), and a Telegram channel. All of them are free, require no account, and show the same map and alerts.
Download for iPhone (iOS)
The Mahsa Alert app for iPhone and iPad is on the App Store: download from the App Store. If you cannot reach the App Store, the web version (below) offers the same features.
Download for Android
The Android version is on Google Play: download from Google Play. If Google Play is unavailable, install the web version instead; the experience is nearly identical.
Web version (no download needed)
The web version runs in your browser and can be installed to your home screen as a PWA: open mahsaalert.app and choose "Add to Home Screen" from the browser menu. Once installed it opens like a regular app with its own icon, receives notifications, and caches map data for weak connections.
The web version is the best option when app stores are unreachable, and it always runs the latest release without manual updates.
Telegram
If you prefer no app at all, alerts are also relayed on our Telegram channel: t.me/mahsa_alert. You can also submit reports from inside Telegram via the Mahsa Alert bot.
After installing
Enable notifications so urgent alerts reach you, and toggle the map layers you care about. See the how-to-use guide for details.
