A powerful GPS speedometer, mileage tracker, and trip-cost monitor with dash-cam and action-cam video. See your speed at a glance, receive clear speed-limit alerts, record detailed routes, and understand the real cost of each trip. Features: ■ Speed Limits & Alerts Set speed limits with 4 or 8 one-tap presets. Large digits change from green to red and a sound alerts you when you exceed the selected limit. The app can remember where limits were used and reapply them automatically. ■ Cost, Fuel & EV Monitor See driving costs in real time for combustion and electric vehicles. For fuel, enter price and efficiency (US/UK MPG or L/100 km). For an EV, enter electricity price per kWh, usable battery capacity, full-charge driving range, and charging efficiency—the app accounts for charging losses. Add optional charges per mile or kilometer, split costs between passengers, and monitor estimated remaining range with configurable alerts. ■ GPS Tracking Record detailed mileage and routes, review speed, altitude, and statistics, or add a previous track back to the map to retrace it. Import and export GPX, KML, and KMZ files. ■ GPS Dash Cam & Action Cam Video Record the road or the action with synchronized speed, location, heading, and map data. Choose engaging overlays such as speed, map, Pitch & Roll, and G-Cross for live view, replay, or stamped exports. Keep a clean original, export a full video or selected range, and turn an exact replay frame into a georeferenced photo and waypoint. Loop recording can retain the latest part of a drive without filling storage with one endless recording. Because of iOS privacy restrictions, video can be recorded only while the camera recording screen is visible. Recording stops if you leave that screen or the app moves to the background. The app does not provide parking surveillance or automatic vehicle-power startup. ■ Mileage Calculator & PDF Reports Calculate distance, fuel costs, and mileage between addresses. Fill gaps in a mileage log, categorize trips, and create customizable professional reports for reimbursement or tax records. ■ Maps Choose Apple, Google, blank, or offline road, satellite, and topographic maps. Import MBTiles or SQLiteDB maps, download maps in the app, and create or share KMZ ground overlays. ■ Driving and Navigation Modes Use a full-screen speed display, mirrored HUD, rally computer, G-Force monitor, taximeter, map, water-sports mode, idle timer, paragliding instruments, or directional navigation for land, air, and marine use. ■ Waypoints & Camera Alerts Create waypoints with optional photos or audio notes. Receive approach alerts, apply speed limits, and import or export CSV, GPX, KML, and KMZ data. Import red-light and speed-camera data or use the built-in library. ■ Voice Coach & Siri Shortcuts Hear distance, duration, speed, and altitude at chosen intervals. Start or stop GPS tracking and set speed limits with Siri. ■ Barometric Instruments View real-time vertical speed and altitude with QFE/QNH support on compatible devices. ■ Background Mileage Tracking The speedometer and GPS track recorder can run in the background when enabled. Optional auto-recording logs driving without manual start or stop, ideal for tax or reimbursement mileage. It includes 50 free auto-tracks per month, with an upgrade available for unlimited use. ■ Speed & Distance Displays 0–999 in MPH, km/h, or knots, plus maximum and average speed, distance, altitude, and sunrise/sunset times. ■ Privacy & Compatibility Location data is used for speed monitoring and trip recording within the app and is not shared with third parties. Requires an iPhone or cellular iPad with GPS; Wi-Fi-only iPads and iPods need an external GPS source. Continued GPS use can reduce battery life.
