<p>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.</p><p>When something goes wrong, it sends an SMS alert with your GPS coordinates to your emergency contact. No internet connection needed.</p><p>Smart Fall Detection (Smart Sentinel)</p><p>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.</p><p>Activity profiles</p><p>Pick the profile that matches what you're doing — Smart Sentinel adapts its sensitivity: - Trekking / Hiking: balanced default for walking outdoors. - Running (road): tuned for the sustained high-G cadence of road running, with an adaptive rhythm detector. - 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.</p><p>Inactivity Monitor (Dead Man's Switch)</p><p>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.</p><p>Live Tracking</p><p>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.</p><p>Dying Gasp</p><p>When the battery drops below 5%, a final SMS with your last GPS position is sent automatically before the phone shuts
