SpeedWatch
Read full descriptionHide full description
SpeedWatch turns your iPhone into a speedometer you can actually read at a glance. One huge number. Colours that tell you instantly whether you are inside your limit. And alerts that speak up before a camera does. WHY DRIVERS USE IT Your car's dial is small, awkwardly placed and never tells you how close you are to the limit. SpeedWatch gives you a full-screen GPS gauge that turns green, yellow, orange or red based on the limits YOU set for city, out-of-town and highway driving. One look and you know. BUILT FOR THE ROAD • Large live GPS speedometer in km/h or mph • Four-zone colour coding driven by your own limits • Quick presets for City, Outside city and Highway — tap to switch • Live Activity on the Lock Screen and in the Dynamic Island • Apple Watch app so your speed is on your wrist • Night HUD: swipe in for a pure-black heads-up display that can mirror onto your windshield • Section Control: measure your true average speed over a stretch of road • Live map with your street name, compass heading, temperature and conditions • Drives start and stop by themselves, and end about a minute after you park AFTER EVERY DRIVE The moment a drive ends you get a summary: distance, duration, top and average speed, and how much of it you spent over your own limit. If your phone was in your pocket it arrives as a notification and waits for you. Share any drive as a card, whatever you paid. KNOW EVERY DRIVE Every drive records duration, distance, top speed and average speed, and is labelled as a car trip or a bike ride. Open one to see the route on a map with the speed chart beside it. Filter your history, export it all to CSV, or clear it out in bulk. Statistics add totals, trends per week, month or year, and how much of your driving time sits over the limit. MILEAGE FOR WORK Mark a drive business or private the moment it ends, or with one swipe in the list. SpeedWatch then exports a mileage report as a PDF: distance totalled per purpose, then one line per trip with date, start, end and distance — ready for your employer or your accountant. DASHCAM Record the road ahead with your speed burned into the clip. A hard jolt marks that clip so the storage limit will not delete it later. Clips are kept in a library on your device, ready to review, share or delete. ON YOUR HOME SCREEN Two widgets show your last drive and the distance you covered this week. "Start a drive" and "Stop the drive" work through Siri and Shortcuts, and starting one is a Control Center button away. OFFLINE SPEED LIMITS • Offline speed limits: download your country once, then see the limit of the road you are on • Warnings for fixed speed cameras, only where the law allows them Limits are approximate: the sign on the road always wins. PRIVACY FIRST No account and no sign-up. SpeedWatch has no server of its own: your drives, clips and settings are kept on your iPhone, and with Plus your drives are also backed up to your own iCloud. Weather and maps come from Apple. PRICING — BUY ONCE, KEEP FOREVER SpeedWatch is free to use. Two one-time unlocks, no subscription: • SpeedWatch Plus — offline speed limits, over-speed alerts with sound and haptics, the night HUD, dark mode and eight accent colours, 30 days of statistics, the Home Screen widgets, and your ten newest drives with their routes • SpeedWatch Pro — the whole drive history, the mileage log as a PDF, CSV export, bulk clean-up, your own trip labels and the dashcam. Everything you can turn into money or evidence. Includes everything in Plus. Not sure? Run Pro free for seven days, once, straight from the upgrade screen. No card, no account, nothing to cancel. IMPORTANT SpeedWatch measures speed from GPS. Accuracy depends on satellite reception and it is not a legal replacement for your car's speedometer. The mileage report is a record of what you drove, not tax advice. Always keep your eyes on the road and follow local law — never operate your iPhone while driving.
Speedometer One
Read full descriptionHide full description
Speedometer One shows how fast you’re going in big, clear numbers on iPhone and Apple Watch. When GPS can’t give a reliable reading, it shows -- and tells you why, instead of a made-up 0 or an old speed. Features Big Numbers Your speed fills the middle of the screen, and the arc of the gauge fills as you go faster. Tap the number to switch between mph, km/h, and knots. The screen stays on while Speedometer One is open. Honest Readings Until there’s a reliable GPS fix, the speed shows -- with a status such as Locating… or Low GPS accuracy. If the signal is lost, for example in a tunnel, your last speed stays on screen, dimmed, with the time since the last fix, then clears. Apple Watch See your speed in big numbers on your wrist, and tap the screen to switch units. The Apple Watch app is included, with no purchase needed. Readable at Every Size The speed, labels, and buttons grow with your text size, up to the largest accessibility sizes. VoiceOver reads your speed in full and tells you when the GPS signal changes. Speedometer One Pro A one-time in-app purchase adds: • Map Background — A map sits behind your speed and turns with your direction of travel. The map is built into the app, so it works without a cellular or Wi-Fi connection. • Lock Screen and Dynamic Island — A Live Activity keeps your speed and max in view without opening the app. Turn on Start Automatically to start it when you leave the app while you’re moving. • Max Speed — Your top speed, from accurate GPS readings only, kept until you reset it. • Elevation — Your altitude below your speed, in feet or meters. • Heading — The direction you’re going, as an arrow and as a compass point with degrees. • Night Mode — The display turns red on black to protect your night vision, and the map and status bar are hidden. • Haptics — Feel a tap when you set a new max speed, and a tick when you change units. Privacy Speedometer One has no accounts, ads, or tracking. Your speed is worked out on your iPhone, and your location history isn’t saved. With the map on and an internet connection, Speedometer One asks Apple’s location services for the name of the nearest town or city to show on screen. Requirements: • Speedometer One Pro is a one-time purchase, with no subscription. The Apple Watch app doesn’t need Pro. • Dynamic Island is available on supported iPhone models. • Place names require an internet connection. The map shows where you are. It doesn’t give directions.
