Map Telemetry
GPS & Road Sensor Data Logger
Free · Designed for iPad. Not verified for macOS.
Speed limits as a persistent map overlay, trip auto-stop summaries, voice picker with previews, and new traffic feeds for FR, NZ, AU, FI, and London TfL.
Maps Telemetry turns your iPhone into a professional-grade GPS and sensor telemetry unit that publishes live data over MQTT.
PRICING
Free to download and use. A subscription model is planned for a future update — Free, Standard ($4.99/mo · $39.99/yr), and Fleet ($14.99/mo) tiers. If you are using the app before subscriptions launch, all features you use today will remain free permanently.
BACKGROUND TELEMETRY
GPS, accelerometer, gyroscope, barometer, and noise data are published continuously via MQTT — even with the screen off. Every payload includes position, speed, altitude, heading, HAE, circular error (CE), and linear error (LE) for high-accuracy workflows.
ROAD MAPPING
Record GPS traces with per-point road grade (slope %) and roughness (m/s²) sampled at maximum sensor rate. Review results as a colour-coded 3D route in MapLibre — toggle between grade and roughness overlays. Choose from five transport modes: Driving, Walking, Cycling, Boat, or Train. Export to GPX, CSV, GeoJSON, or KML for any GIS tool.
LIVE TRAFFIC CAMERAS
Real-time 511 traffic cameras for Ontario, Quebec, Alberta, and British Columbia overlaid on the map. Tap a camera and swipe between multiple angles at the same intersection. Quebec streams live MP4 video; other provinces show refreshing JPEG stills.
ROAD ALERTS
Real-time 511 road conditions for ON, QC, BC, and AB overlaid on the map. National NAAD emergency alerts included. Speed camera, red-light camera, school zone, and playground zone warnings as you approach.
NAVIGATION
Turn-by-turn with auto-advancing steps, live distance countdown, automatic off-route detection and rerouting. Live speed-limit display in the nav panel. Long-press any road to preview a re-route through it. Reorder, optimise, and add stops mid-route.
VEHICLE PROFILES
Save multiple vehicles (car, van, truck, motorcycle, EV, EV truck). Per-vehicle dimensions: length, height, width, weight, trailer, fuel type, icon. Active vehicle drives height- and weight-aware routing — avoid restricted roads and get warned when a route exceeds your vehicle's limits.
CARPLAY
Dedicated CarPlay dashboard with live telemetry, navigation, and quick actions: drop a Waypoint, Report an incident (Pothole / Hazard / Police / Accident), End route. During navigation, three upcoming directions are visible at once (NOW · NEXT · AFTER) plus a Steps button for the full list.
2D & 3D MAPS
MapLibre 2D and Apple Maps 3D with live position tracking, heading-follow, and terrain. Long-press the map for Go Here, Add a Stop, or Report an Event. Light, Dark, or System theme.
ROAD EVENT DETECTION
Automatic detection of potholes, hard braking, hard acceleration, and swerve events using the IMU. Trip report and drive score after each session. Events are timestamped and geotagged.
EXPORT
Share sessions as GPX, CSV, GeoJSON, or KML via AirDrop, Mail, or Files. Import GPX routes from Files or AirDrop.
PRIVACY
By default, telemetry is published to a secure MQTT service operated by the developer in Canada (AWS IoT). No data is sold or shared with third parties. Data is retained for up to 90 days and then deleted automatically. You can request immediate deletion or a copy of your data at any time by emailing support@mapgeometrics.com.

Ratings & Reviews
Version 1.2.1 is a major update built around full turn-by-turn navigation, with CarPlay improvements, smarter traffic alerts, and a long list of refinements.
TURN-BY-TURN NAVIGATION
- Full turn-by-turn navigation with spoken voice guidance.
- A Go Here preview shows driving distance, heading, and ETA before you commit to a route.
- Search with saved Places — Home, Work, favorites, and recent searches — and results now favor your area.
- Lane guidance and exit numbers in the turn banner.
- A live turn banner with remaining distance and ETA that updates as you drive, plus a lock-screen banner and an in-app heads-up about 15 seconds before each maneuver.
- Step tracking reworked for reliability through wide intersections, off-ramps, missed turns, red lights, and stop-and-go traffic.
- Choose any iOS system voice and audition it before selecting.
CARPLAY
- An upcoming-maneuver NEXT row on the CarPlay screen.
- A scrollable Report incident list with Cancel always reachable — and the list now stays on screen reliably.
- Distance to the next step stays accurate through wide intersections and off-ramps.
- Music resumes faster after each spoken instruction.
SMARTER TRAFFIC ALERTS
- Incidents anywhere along a planned route surface immediately, sorted by distance ahead.
- Distant accidents are hidden because they usually clear before you arrive; construction, closures, and hazards are always shown.
ACCURATE SPEED LIMITS
- The speed-limit badge uses your heading to pick the correct road, so it stays accurate on overpasses, at intersections, and on roads running parallel to a highway.
- A flashing speed-limit alert with a threshold you can set.
TRIPS AND RECORDING
- A Past Trips archive keeps every recording you finish, browseable any time.
- Choose Cloud plus local or Local only when you start a recording.
- Auto-stop after the vehicle has been stationary, with Off, 1, 2, and 4 hour options.
- An end-of-trip summary with distance, duration, speeds, climb, and a driving score.
MAPS AND CUSTOMIZATION
- Apple Maps photoreal Flyover with 3D buildings and terrain on iOS 16 and later.
- An automatic dark and light theme that follows sunset and sunrise.
- Adjustable road-map color thresholds, elevation profiles for traced routes, and saved routes.
- Many new international traffic feeds covering the UK, Australia, New Zealand, Finland, Norway, the Netherlands, and more.
RELIABILITY AND PRIVACY
- Publish only while recording now reliably stops all background data sharing when it is turned off.
- Community hazard and pothole reports again reach other devices in your group.
- Trips are preserved completely, with no lost final seconds when you start fresh.
- Broad security and stability hardening across data feeds, file imports, and background services.
