How do I start, and which throttle controls can I use?
On iPhone, choose an engine in the garage, tap Start Engine, then choose rotation or touch throttle. On Apple Watch, start an engine and use wrist rotation, the Digital Crown, or the touch slider. Pro engines and gauges prompt you to unlock when used.
What does Calibrate do?
Calibration sets the current device position as the reference for motion throttle. Hold your phone or wear your Watch in a comfortable, relaxed position, tap Calibrate, then rotate to try the throttle. Recalibrate if the throttle is not where you expect at rest. Touch sliders and the Digital Crown do not rely on calibration.
Why is there no sound on Apple Watch or iPhone?
Start the engine, check the output device shown in the app, and check system volume and Bluetooth connections. Some Apple Watch models require Bluetooth headphones or a speaker. If sound goes to an unwanted device, change the system audio output, return to the app, and try again.
Do I pay for each engine separately?
No. One Air Moto Pro purchase unlocks the other seven engines and two extra gauges. Every Pro label refers to the same purchase. There is no subscription. The App Store purchase screen shows your local price and currency.
How do I restore Pro after reinstalling or changing devices?
Choose Restore Purchases on the Pro screen or in Settings, using the Apple Account that originally bought Pro. Restoring a valid purchase does not require buying the same Pro product again. An internet connection is needed to verify access.
I bought Pro on iPhone. Why is my Watch still locked?
Keep your iPhone and paired Watch connected and open Air Moto on both. Restore Purchases on iPhone, then return to Watch and allow time for access to sync. If needed, try Restore Purchases on Watch, check the purchasing App Store account on both devices, and update both apps to the same version. Contact support if it still does not unlock.
What if the purchase screen says unavailable or asks me to retry?
Check your connection, App Store account, and whether in-app purchases are allowed. Close and reopen the unlock screen. Send the exact message or error code to support with your device, OS, and app version. A canceled purchase can be retried later; an unfinished purchase does not unlock Pro.
How do I change gauges, and what is different?
On the engine screen, tap Gauge Style to choose Digital Duo, Classic Dual Ring, or Race Dash. All three put simulated speed first and RPM second. The last two require Pro. iPhone and Watch share the same gauge styles.
Are speed and RPM real measurements?
No. They are calculated from the virtual engine state, without GPS or a connection to a real motorcycle. Engine sounds are original synthesized interpretations, not recordings of particular models. These features are for entertainment.
Which devices do I need? Is an account or internet required?
The current version requires iOS 18.0 or later, or watchOS 11.0 or later. iPhone and Watch can run independently. No developer account is required. Purchases, restoration, and app updates use Apple services and need an internet connection.
