Oksigenia SOS is an offline-first personal safety app for outdoor sports and high-risk environments. No account, no cloud, no Google Services required — everything runs on your device.

When something goes wrong, it sends an SMS alert with your GPS coordinates to your emergency contact. No internet connection needed.

Smart Fall Detection (Smart Sentinel)

The accelerometer monitors you continuously at high frequency. A sudden impact triggers an observation window. If sustained walking movement is detected during that window, the alarm is dismissed automatically — false positives from drops or normal jolts won't fire the SOS. If no rhythmic movement is detected, the SOS is sent.

Activity profiles

Pick the profile that matches what you're doing — Smart Sentinel adapts its sensitivity: - Trekking / Hiking: balanced default for walking outdoors. - Trail running / MTB: higher impact threshold for terrain with constant vibration. - Mountaineering: longer observation window for slow recoveries on technical ground. - Paragliding / Kayak / Watersports: automatic fall detection is disabled (the sensor cannot reliably interpret flight or water motion); inactivity monitor and manual SOS remain active. - Professional / Rescue: extended observation window for advanced operational use.

Inactivity Monitor (Dead Man's Switch)

Set a check-in timer. If you don't confirm you're OK before it expires, the alert is sent automatically. Essential for solo adventures where a fall might leave you conscious but unable to call for help.

Live Tracking

Send your GPS position by SMS every 30, 60 or 120 minutes. Pause, resume or check in manually at any time — without stopping the monitoring session.

Dying Gasp

When the battery drops below 5%, a final SMS with your last GPS position is sent automatically before the phone shuts down.

Privacy and Compatibility

No account or registration required
All data stays on your device — no cloud sync, no telemetry
No trackers, no analytics, no ads
Works on de-Googled phones (GrapheneOS, MicroG)
Open source under GPLv3

Available in 8 languages: English, Spanish, French, German, Portuguese, Italian, Dutch and Swedish.

IMPORTANT: Oksigenia SOS is a support tool and does not replace professional emergency services. Its operation depends on mobile coverage, GPS signal and battery level.

WhatsNew:

Reproducible Build hot-fix. The GitHub Actions release workflow now strips the build-id embedded by the linker into libdartjni.so (transitive jni dependency). Without this patch, each build produced a slightly different shared library and the APK failed IzzyOnDroid RB verification.

No app behaviour changes vs v4.1.0 — Smart Beacon, the Equitation profile and the three new languages (Polish, Russian, Norwegian Bokmål) all behave identically. This release exists to give IzzyOnDroid a bit-for-bit

Download Metadata Source Issues ChangeLog

While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device. Some clients have this repo enabled by default, e.g. Neo Store, Droid-ify, or, of course, the IzzyOnDroid client by Sunil. With others (like the official client) you'll have to add this repo manually (see the hint on top of the package list for how to do that).
