Question 1

Does Speedometer work on Apple CarPlay?

Accepted Answer

Yes. Speedometer is a native CarPlay app, which means it runs on your car's built-in screen alongside Apple Maps, Music, and your other CarPlay apps. When you connect your iPhone to CarPlay, you'll see Speedometer's icon on the CarPlay home screen — tap it to view your real-time GPS speed, current trip stats, and route on the dashboard. The iPhone display can show something different (or stay locked) while CarPlay handles the in-car view.

Question 2

Does Speedometer support wired and wireless CarPlay?

Accepted Answer

Speedometer supports every type of CarPlay your car offers: wired (USB Lightning or USB-C cable) and wireless. It's a standard CarPlay app, so however your iPhone connects to your car — plugging in a cable or connecting over Bluetooth + Wi-Fi for wireless CarPlay — Speedometer is available on the CarPlay home screen as soon as the connection is up.

Question 3

What does Speedometer show on the CarPlay screen?

Accepted Answer

Speedometer's CarPlay view is designed for one job: glanceable driving data, optimized for the car. You'll see your real-time GPS speed in large, high-contrast type, plus current trip stats (distance, duration, average and max speed) when a trip is active. Layouts follow Apple's CarPlay design system so everything stays readable at speed and switches between day and night modes automatically with the rest of CarPlay.

Question 4

How do I add Speedometer to my CarPlay home screen?

Accepted Answer

If Speedometer isn't already showing on your CarPlay home screen, you can pin it manually:

1. On your iPhone, open Settings → General → CarPlay.
2. Tap your car from the list.
3. Tap "Customize" (or the edit/grid icon).
4. Find Speedometer in the lower section and tap the green plus to move it to the visible apps section.
5. Drag to reorder — apps near the top appear first on the CarPlay home screen.

Disconnect and reconnect to see the change. You can also rearrange directly on your CarPlay screen by long-pressing any icon.

Question 5

Can I use Speedometer alongside Apple Maps, Google Maps, or Waze on CarPlay?

Accepted Answer

Speedometer doesn't replace your navigation app — it complements it. On modern CarPlay layouts (iOS 16+), the dashboard view can show Apple Maps turn-by-turn navigation alongside other live data, and you can switch between Speedometer and Maps as full-screen views with a single tap. Trip recording continues in the background regardless of which app is currently visible. Live Activities and Dynamic Island also surface Speedometer's trip stats on your iPhone's lock screen at the same time.

Question 6

Does Speedometer's CarPlay view support day and night modes?

Accepted Answer

Yes. Speedometer's CarPlay UI uses Apple's standard appearance system, so it automatically follows CarPlay's day and night modes — lighter colors and brighter contrast in the daytime, darker low-glare interface after sunset (or whenever your car switches to night mode). You don't need to configure anything.

Question 7

Which cars work with Speedometer on CarPlay?

Accepted Answer

Speedometer works with every car that supports Apple CarPlay. Apple maintains an official list of CarPlay-compatible vehicles at apple.com/ios/carplay/available-models — but in practice, almost every new car sold since 2018 supports it, plus aftermarket head units from Pioneer, Sony, Kenwood, Alpine, and others. If your car shows the CarPlay home screen when you connect your iPhone, Speedometer will appear there.

Question 8

Why isn't Speedometer showing on my CarPlay home screen?

Accepted Answer

If Speedometer doesn't appear on your CarPlay home screen after installing or updating the app, the most common reasons are:

1. **Customize layout hides it.** Open iPhone Settings → General → CarPlay → tap your car → Customize. Speedometer may be in the lower (hidden) section — tap the green plus to move it up.
2. **App needs an update.** Make sure you have the latest version of Speedometer from the App Store. CarPlay support requires the version that shipped with the entitlement.
3. **iPhone or iOS too old.** Speedometer requires iOS 17 or later. Check Settings → General → Software Update.
4. **CarPlay connection issue.** Disconnect and reconnect (unplug the cable, or toggle Bluetooth for wireless CarPlay). Restart your iPhone if needed.
5. **Restrictions enabled.** If you have Screen Time content restrictions, Settings → Screen Time → Content & Privacy Restrictions → Allowed Apps → make sure CarPlay apps aren't restricted.
