What people complain about
In the one- to three-star reviews of speedometer apps, the same problems come up again and again:
| Complaint | Share of low reviews |
|---|---|
| Shows 0, freezes or "doesn't work", often on trains | About 1 in 4 |
| Ads, including ads covering the reading while driving | About 1 in 5 |
| Paywalls, weekly subscriptions and trials that turn into charges | About 1 in 6 |
| Wrong readings, such as speed while sitting still | Common |
From our analysis of 7,688 reviews of 14 speedometer, compass and altimeter apps in the US, UK, Australian, Canadian and German App Stores, October 2026. Shares are approximate.
And in the five-star reviews, people praise the opposite: accurate, simple, readable, free, no ads, works offline. So that is the checklist.
1. Nothing in front of the number
A speedometer is read in a glance, often while driving. An ad that covers the reading, or a pop-up that asks for a rating at 70 mph, is not just annoying; it is the moment you look at the phone longest. Vane has no ads at all, in the free version or anywhere else.
2. Honest readings
Every phone loses the satellites sometimes: tunnels, car parks, train carriages. What matters is what the app does then. Showing the last speed frozen, or a confident 0, looks right and is wrong. Vane labels every reading with the sensor it came from, says in plain words how good the satellite fix is, and shows dashes instead of a guess when there is no fix. See why GPS stops in tunnels.
3. Big, clear and calm
Large numbers, high contrast, nothing blinking. Vane's dash is one large speed on a dark instrument face, with heading, altitude and top speed below it, and it follows the text size you set on your iPhone.
4. A head-up display that reads the right way round
At night, a phone lying under the windscreen can project the speed onto the glass. That only works if the app mirrors the display, so the reflection reads correctly. Vane's head-up display is mirrored and shows the speed very large on black.
5. Works with no signal bars
GPS needs no mobile data, but most apps' maps do. Vane's map of roads, railways, borders and towns is built in, so your track, your parked car and your saved places show up in the mountains, at sea or abroad with roaming off. See does GPS work without internet?
6. More than a speedometer
The people who use speedometer apps are drivers checking their car, cyclists, sailors, pilots in the back of a plane and hikers. One app can serve all of them. Vane is a speedometer, compass, barometric altimeter, spirit level and position readout in one, with trip recording, a mileage log, GPX import and an anchor alarm.
7. On your wrist
A watch is the easiest place to glance at speed on a bike or a boat. Vane has an Apple Watch app with speed, heading and altitude, and it saves walks, hikes, runs and rides to the Health app with their route.
8. Fair pricing
The angriest reviews are about weekly subscriptions and free trials that quietly turn into charges. Vane's instruments are free and stay free. Vane Pro is optional, has no weekly plan and no free trial that bills you later, and can be bought once instead of as a subscription.
9. Private
A speedometer has no reason to know who you are. Vane has no account, no ads and no tracking. Your trips stay on your iPhone, or in your own iCloud if you turn on sync.
Try it before you install anything
Our free online speedometer runs in your phone's browser and shows your GPS speed in seconds. When you want it with the screen off, on your watch, with a head-up display and a map, that is Vane.
Common questions
What is the best speedometer app for iPhone?
Look for an app with no ads over the reading, a large clear display, honest readings that say when the signal is weak, an offline map, an Apple Watch app and a mirrored head-up display, with no weekly subscription. Vane was built around exactly that list: it is free with no ads, adds a compass, barometric altimeter and spirit level, and offers Pro as a subscription or a one-time purchase.
Is there a free speedometer app without ads?
Yes. Vane's speedometer, compass, altimeter, level, head-up display, offline map and trip recording are free, with no ads and no account.
Are iPhone speedometer apps accurate?
In open sky they read speed from the phone's satellite receiver, typically to within about 1 km/h, which is usually closer than a car's own speedometer. They are less reliable among tall buildings and have no signal in tunnels, where a good app shows no reading rather than a frozen or zero one.
Does a speedometer app work without internet?
GPS speed needs no mobile data. The map is the part that usually needs data, unless it is built into the app, as Vane's is.
