How can we help?
How do I record a drive?
Open Kerbmile and press Start. Put the phone away and press End when you arrive. The route and numbers are saved on your phone.
Why does the screen only show big numbers while I drive?
For safety. While the car moves you see kilometers, time and one large End button. There is no map and nothing social, so a quick glance is enough.
How does Auto-record work, and what does it do to battery?
Auto-record (Pro) uses the low power location the system already runs between drives. A drive starts when your iPhone notices you are driving and ends after 5 minutes parked. GPS recording runs only while a drive is recording.
How do crews work, and how do I leave one?
Join a crew with an invite code. The board ranks the crew by weekly kilometers, curvy kilometers or streak, and only weekly totals are shared. To leave, use the Leave crew button at the bottom of the Crew tab. Your record is deleted.
How do I move my drives to a new iPhone?
On the old iPhone, open Settings and choose Export backup, then GPX. Send the file to the new iPhone, open Kerbmile there and choose Import backup.
I paid for Pro on another device.
Open Settings and tap Restore purchase. Use the same Apple account you bought with.
How are curvy kilometers counted?
Curvy km is the distance on road stretches where the heading keeps turning. It is measured on your device from the GPS route.
