SpeedWatch: GPS Speedometer

Now with a full dashcam, a night HUD and landscape support. Your speed burned straight into the footage — and nothing ever leaves your phone.

SpeedWatch turns your iPhone into a precise GPS speedometer — and now into a dashcam that burns your speed straight into the video.

No account. No sign-up. No servers. Everything stays on your device.

THE SPEEDOMETER

• Large, glanceable gauge that changes colour as you approach your limit • Works from GPS — no adapter, no pairing, nothing to install in the car • km/h or mph, °C or °F • Compass heading, street name and live weather at a glance • Map preview with street, satellite and hybrid views • Portrait and landscape — turn the phone in its mount and the whole dashboard rearranges itself

DASHCAM (Pro)

Record the road ahead while you drive, with your speed permanently in the picture.

• Continuous loop recording in 3-minute clips • Speed, date and time, GPS coordinates, street name and temperature burned into the video — each one switchable • Automatically deletes the oldest clip when it reaches its 2 GB limit • Optional audio, off by default • Built-in library: watch, share or delete any clip • Tap the preview to dim the screen and keep the phone cooler • Clips are stored on your device only. Nothing is uploaded, ever.

Please note: iOS does not allow any app to use the camera in the background, so recording runs while the dashcam screen is open and pauses if you switch apps or lock the phone.

NIGHT HUD (Plus)

Swipe in from the right edge for a pure black driving display: the gauge at full size, your heading and the street you are on. Flip on mirror mode, lay the phone flat on the dashboard, and read your speed in the reflection of the windshield.

SPEED ALERTS (Plus)

• Three presets — City, Outside city, Highway — each with its own limit • Pick a different sound and haptic per preset • Set a minimum quiet time between alerts so long drives stay calm • Dark mode and app themes

TRIP LOGGING (Pro)

• Sessions start and stop on their own when you begin and end driving • Duration, distance, maximum and average speed for every trip • Full history with filters and per-trip detail • Export to CSV and share

SECTION CONTROL

Measuring your own average over a stretch of road is one tap on the gauge. Watch your running average and keep it where it should be.

LOCK SCREEN, DYNAMIC ISLAND AND APPLE WATCH

Your speed follows you: a Live Activity on the Lock Screen and in the Dynamic Island while a trip is running, and a companion app on Apple Watch.

A WORD ON SAFETY

Mount your phone before you set off and keep your eyes on the road. SpeedWatch is a driving aid, not a substitute for your car's speedometer or for paying attention. GPS speed can differ from your dashboard reading, and it needs a clear view of the sky.

Recording audio alongside video is subject to local law, and the rules differ by country and by region. Audio is off unless you turn it on.

Requires iOS 26. Plus and Pro are one-time purchases — no subscription.
