Speedometer HUD GPS
Read full descriptionHide full description
Speedometer shows your speed clearly and accurately straight from GPS: in your car, on your bike, on a boat or on foot. WHY THIS ONE Most speedometer apps show you a number and hope you trust it. This one shows the number and the GPS accuracy behind it, so you always know whether the fix is good to 3 metres or only to 40. Weak fixes are weighted down instead of being drawn as spikes, and your trip's top speed is only updated from a reading the app considers reliable. One bad GPS jump will not become a record you never drove. And it stays out of the way: no ads, no analytics, no account, no cloud. Nothing is uploaded, because there is nowhere to upload it to. FREE - Accurate real-time GPS speed with a live accuracy readout - Clear display styles: digital LED readout and car-style gauge - Distance, average speed, top speed and trip time - Units: km/h, mph, m/s, knots, ft/s - HUD mode: mirrored display for windshield reflection - Dark and light themes, selectable LED colors - Tracking continues in the background even with the screen locked - Speed limit alert: set your own limit and get sound, vibration and a flashing warning - Trip summary right after every trip: distance, time, moving time, average and top speed PREMIUM - Extra display styles: KITT arc, 7-segment display, bar meter and minimal dial - Cycling and walking modes with fitting gauge scales - Trip history with route maps and statistics - Map view with real-time route drawing - Export any trip as GPX or CSV and share it anywhere TWO WAYS TO GET PREMIUM - Yearly subscription, cancel anytime in your App Store account - One-time purchase: pay once and keep Premium forever, no renewals, no subscription PRIVACY - No ads, no analytics, no account - Measurements and trip history are stored only on your own device NOTE: This app is not a navigation device. Always obey traffic rules and speed limits, and keep your eyes on the road. GPS accuracy depends on your device and conditions. Continuous GPS use may increase battery consumption.

Verdict
The clearest difference is in-app purchases: Speedometer HUD GPS at none against G's 1. Speedometer HUD GPS also leads on ads (none vs shown). G's advantage is update cadence (every 5 days vs every 6 weeks) and iOS requirement (13.0 vs 15.0). On price and device support there is nothing between them.
