Get clearer speed, route and driving feedback in a couple of taps with GPS Speedometer: MPH Tracker. Use live mph, HUD alerts and trip records when your dashboard is not enough. GPS Speedometer: MPH Tracker helps you check speed, follow limits and review each journey without extra hardware. It is built for everyday driving, motorbike rides, cycling, running, boating and other movement where a simple spd readout, timer, distance view and route log can be useful. SMART DRIVING INSIGHTS · Speeding heatmap for repeated risk areas · Hard braking heatmap after each route · Driving smoothness and safety score · G-force meter for braking and cornering · Peak G-force and sharp movement notes · Weather-aware road condition advice · Wet road, ice, fog and wind prompts · Route replay with speed-coloured track · Stops, peak speed and route scrubber · Attempt history for 0-60 and 0-100 · Speed-time graph with auto start · Best run saved for later comparison LIVE SPEED TOOLS · Large GPS speedometer for quick reading · Smart speed limit alerts on the road · Voice warnings before you drift over limit · Speed camera alerts where available · HUD windshield mode for night driving · Picture-in-Picture speed overlay · Car, motorcycle, bicycle and running modes · Boat and airplane speed layouts · Custom dashboard skins for clear viewing · Odometer, mileage log and tripmeter · Live map with compass and distance · Background tracking with power-saving mode · Apple Watch speed, distance and trip time · Over-limit alerts on your wrist With GPS Speedometer: MPH Tracker, you can keep the important numbers visible without switching between several screens. The app combines live speed, limit warnings, route history and driving behaviour notes in one place, so you can decide what to check now and what to review later. Use the big mph display for a clean current reading. Switch to heads-up mode when you want the speed reflected on the windscreen. Keep Picture-in-Picture active if you need a small speed panel while using another navigation view. Trip recording is useful when you want more than a momentary number. GPS Speedometer: MPH Tracker can save duration, distance, stops, peak speed and route details. After the journey, route replay lets you move through the drive with a scrubber and see where speed changed along the road. The acceleration tools are made for measured runs, not guesswork. Start a 0-60 or 0-100 attempt, let auto start handle the launch, then review the timer, speed-time graph, previous attempts and your best run. It also helps when comparing a-speed changes after maintenance or different conditions. How it works Open GPS Speedometer: MPH Tracker, choose the movement mode and allow location access. The app uses GPS data to calculate live speed, distance and route information. Accuracy may vary with signal quality, tunnels, tall buildings, device placement and local road data. Turn on the alerts you want before you set off. You can use voice speed warnings, limit prompts, camera notices, HUD mode, live map tracking or Apple Watch companion views. For longer journeys, background trip tracking and power-saving mode help keep the essentials running. Premium access unlocks the extended set of tracking, dashboard, alert and history tools inside GPS Speedometer: MPH Tracker. If you choose a subscription, it renews on its own unless auto-renewal is turned off at least 24 hours before the current period ends; you can manage or cancel it from your account settings.
