Incident Detection

Automatic crash detection, check-ins, and emergency alerts for your rides, runs, hikes, and gym workouts.

Available now on Google Play

What it does

Session tracking

Bike, ride a motorcycle, run, walk, hike, drive, or kayak/canoe — GPS route on a map, distance, speed, duration, and elevation gain, plus heart rate and cadence from an optional paired Bluetooth sensor, saved to your session history.

Crash detection

A sudden spike in acceleration and rotation, confirmed by a sharp drop in GPS speed, triggers a countdown you can cancel if you're fine.

Emergency alerts

If the countdown runs out, your emergency contacts are notified automatically — by SMS and, for your primary contact, an automatic phone call.

Check-in mode

Skip activity tracking entirely — just answer "still OK?" at whatever interval you choose, with the same emergency alert if you don't respond.

Gym mode

For workouts where your phone stays on the bench, not on you — confirm "I'm OK" yourself with a tap any time, and pair a heart-rate sensor for automatic detection too, with the same emergency alert if 15 minutes pass unanswered.

Reminders

Predefined prompts like drink water, take vitamins, or stretch — or your own custom ones — running all day or just during a specific activity. Turn on escalation and an unanswered one triggers the same emergency alert as a crash.

Guardian mode

Pair with one or more people's phones over Bluetooth so each of you can tell the other is still nearby — with an automatic alert to your own emergency contacts if you lose contact. Turn it on for a single session too, whatever the activity — if something happens, whoever comes looking can use your phone's Bluetooth signal to search the exact area, e.g. off-trail.

Import & follow routes

Import a GPX file and get turn-by-turn navigation with off-route alerts, or race a past ride as a ghost. Save routes to a library for reuse anytime.

Plan a route

Choose "Plan a route" when picking a navigation route and plan one right in the app, on Google Maps or MapLibre. Set a start (or your location), up to ten stops and a destination for walking, running, cycling or driving, avoid ferries and toll roads if you like, and the route goes straight to turn-by-turn navigation. Switch on "Save to library" to keep it for later. Nothing is sent until you tap Calculate route.

Heart-rate alerts

With a paired heart-rate sensor, a sustained abnormal reading — based on your age and resting heart rate — triggers its own alert, escalating to the same emergency pipeline as a crash if you don't respond. Not limited to workouts: it runs the same way during a Car or Motorcycle session, Check-in, or Guardian mode, so it can catch a medical event even when you're not exercising.

Bike radar alerts

Pair an iGPSport SR Mini radar — the only model currently supported — for a live proximity bar showing traffic approaching from behind, and a close-pass alert that escalates to the same emergency pipeline as a crash if you don't respond.

Training

Follow a structured workout during a Bike or Run session — one of the app's built-in plans, or your own imported as a FIT file — with live targets for heart rate, cadence, power, or speed, and a summary of how you did afterward. Build your own plan right in the app, including repeating interval blocks.

Works without GPS too

Walking or running on a treadmill? Distance and pace are estimated from your phone's step counter — or read directly from a paired Bluetooth treadmill for real speed and distance.

Strava upload (optional)

Connect your own Strava account to upload a finished workout — one at a time, or automatically if you turn that on. GPS-free sessions (treadmill, Gym) upload too, with real speed/heart-rate data and no route needed. Off by default; nothing is sent until you connect an account.

Push notifications without Google (optional)

Guardian mode's remote location sharing can deliver its push notifications over UnifiedPush instead of Google/Firebase — pick any distributor app you like, or use Incident Detection's own built-in one, so no extra app install is required at all. Works fully even on phones with no Google Play Services at all, like GrapheneOS. See the Help & Guide for setup steps.

Maps without Google (optional)

Pick MapLibre as your map source in Settings — powered by OpenStreetMap, CyclOSM, OpenFreeMap, MapToolKit, or MapTiler tiles instead of Google Maps — or let the app choose it automatically on a phone with no Google Play Services at all, like GrapheneOS. No account needed for any of them; only MapTiler requires an API key (the app's own, not yours) — nothing else Google-related involved in showing the map.

Local-first & private

No account, no backend, no analytics, by default. Your routes, sessions, and contacts stay on your device — deleting a session or uninstalling removes them for good. Guardian mode only ever exchanges a random id and a display name directly over Bluetooth with each pairing partner — turning off broadcasting or removing a pairing always requires confirming it's you via your device's own screen lock, so no one else can silently disable it. The one opt-in exception is Strava upload, off unless you connect an account.

Also from us: ID Tools

A separate companion app of utilities for trips and testing: a compass, GNSS and satellite info, go-to-point navigation, an online route planner whose routes you can send straight to Incident Detection as a GPX file, a frequency generator with an SOS tone, and a Location simulator that replays a GPX track as mock location — handy for trying Incident Detection out without leaving the house.
