Digital
A plain numeric readout. The fastest thing to read, and the one that survives a glance.
IPHONE · NAVIGATION
Your speed, read at a glance.
Speedometer turns your iPhone into a GPS instrument cluster. Digital, analog or HUD - pick the face you can read fastest, set your limit, and every trip is logged with its own route map.

THREE FACES
Read your speed the way you think about it.
The same GPS reading, three instruments. Switch between them with one tap at the top of the screen.
Analog
A full gauge dial with a sweeping needle and a configurable scale up to 0-210, for drivers who read position faster than digits.
HUD
A mirrored head-up display you can lay on the dashboard so the windscreen reflects your speed back at you.
WHAT IT DOES
Everything a trip needs, nothing it does not.
Speed-limit alerts
Set a limit and the app tells you the moment you cross it, so you can keep your eyes up instead of on the number.
Live map with speed overlay
Your position on the map with the current speed shown on a seven-segment readout underneath, plus distance and average speed for the session.
Trip recording
Start, pause and stop a session. Elapsed time, distance, average speed and top speed are tracked while it runs.
0-100 acceleration test
Pick a start and a stop speed, hit Start Test, and the app times the run. Results are kept in their own Speed Test History.
Trip history with routes
Every session is saved with distance, total time, moving duration, stop time, average and maximum speed, the route drawn on a map, and the start and finish locations.
Units and transport modes
Switch between KMH, MPH and knots, pick your transport type, and set the gauge scale to match how you actually travel.
IN THE APP
Seven screens, no surprises.
DISPLAY MODES
Live trip
Press Start and the session runs: the timer counts, distance and average speed build, and the top speed of the drive is held. Pause whenever you stop.
- Trip recording with distance, average and maximum speed
- Route map for every recorded trip
Map with speed overlay
Your route as you drive, with the seven-segment speed readout, distance and average speed docked at the bottom.
Acceleration test
Choose a starting speed and a stop speed, then time the run. The result lands in Speed Test History.
Trip history
Every recorded session in one list - distance, total time and average speed - split between trips and speed tests. Distance, total time, moving duration, stop time, average and max speed, the route on a map, and where the trip started and finished.
Settings
Units, transport type, gauge scale, speed limit and theme - plus restore purchases and the legal documents.
HOW IT WORKS
Three taps from install to first trip.
01
Allow location
Speedometer reads GPS to calculate speed, so iOS asks for location permission on first launch. Without it there is no reading to show.
02
Pick your face
Choose Digital, Analog or HUD at the top of the screen, set your units to KMH, MPH or knots, and set a speed limit if you want alerts.
03
Press Start
The timer runs, distance and average speed accumulate, and when you stop, the trip is filed in History with its route.
Accuracy depends on your GPS signal. In tunnels, underground car parks and dense city cores the reading can drift or drop out until the signal returns.

FAQ
Questions people actually ask.
How accurate is a GPS speedometer?
Under an open sky a modern iPhone GPS is typically accurate to within a few km/h, and it measures your true speed over the ground rather than wheel rotation. Accuracy falls where the signal does: tunnels, underground car parks, multi-storey garages and streets hemmed in by tall buildings.
Does it match the speedometer in my car?
Not exactly, and that is expected. Car speedometers are legally allowed to read high and usually do by a few percent, while a GPS reading is based on your actual movement. A small gap between the two is normal.
Does it work without an internet connection?
Speed, trip recording and the acceleration test use GPS, which works without a data connection. The map needs data to fetch new map tiles, so the map view is limited when you are offline.
Does it drain the battery?
Continuous GPS and a screen that stays awake use power, as they do in any navigation app. On a long drive, keep the phone on a charger.
What is the HUD mode for?
HUD mirrors the readout so you can lay the phone flat on the dashboard and read the reflection in the windscreen at night. Only use it where it is legal and where it does not obstruct your view.
How do I cancel the subscription?
Subscriptions are handled by Apple, not by us. Open the Settings app, tap your name, then Subscriptions, and cancel Speedometer there. Cancel at least 24 hours before the period ends to avoid the next renewal.
I bought Premium on another iPhone. How do I get it back?
Open the profile tab and tap Restore Purchases while signed in with the same Apple ID you used to buy it.
Where are my trips stored?
In the app on your iPhone. They are listed under History, where you can open any trip to see its route and delete it whenever you want.

Why GPS Speed Wanders in Cities and Dies in Tunnels
Tall buildings do not block the signal so much as confuse it. Here is what multipath and urban canyon actually do to your reading, and what the app does when the signal disappears entirely.

Analog or Digital Speed Display — Which One Do You Read Faster
Instrument designers have argued about this for a century. The answer depends on whether you need the exact number or the trend, and the app gives you both plus a third option.

Why GPS Apps Drain Your Battery and What Actually Helps
Continuous positioning and an awake screen are the two costs. Here is roughly what each one takes, which fixes are real, and which popular advice does nothing.
