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:
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","categories":["Security"]}
