Features
Everything a ride needs, nothing in the way
The map fills the screen. Only what you need while moving sits on top, and everything else is a swipe away.
Auto-saved rides
Finish a ride and it lands in your logbook with a score, top speed, lean and elevation, even with the screen off.
Group rides
Create a ride, share the code, and see everyone's position, role and speed live. Quick calls are spoken on every phone.
Crash detection and SOS
A loud countdown you can cancel, then your emergency contacts get your location. A drill mode lets you rehearse safely.
Lean angle you can trust
Measured with the gyroscope, so it stays honest through a long corner. Your best left and right lean are logged for every ride.
Pothole alerts for the pack
The lead's hits warn the riders behind. Solo rides stay quiet, and old hazards never clutter a new ride.
A garage that knows your bike
Petrol and electric, with photos. Reminders adapt: no chain lube on a belt drive, a battery check and charging log on an EV.
Route planner
Fastest or twisty roads, alternatives side by side, weather on the way, and a fuel or charging stop check.
Sunlight theme
A high-contrast light look for bright sun, a dark look for night, or follow your phone.
Live voice room New
One voice room for the whole pack with noise suppression. Keep your mic on or hold to talk, and the rider who is speaking pulses on everyone's map.
Group rides
Ride as a pack, stay as a pack
Start a group ride, share the code, and everyone appears on one map with a role. You get warned when the lead and the sweep drift apart.

Install
Up and running in three steps
RevCrank is shared directly as an app file, so Android will ask you to confirm a couple of things. It takes about a minute.
Download
Open this page on your Android phone and tap Download. Wait until it says the file is ready.
Open the file
Tap RevCrank.apk in your notifications or Downloads. If asked, allow your browser to install unknown apps.
Install anyway
If Play Protect says the app is unrecognised, choose More details, then Install anyway. Then allow location, set to Allow all the time.
FAQ
Questions, answered
Why does Android warn me during install?
The app is shared directly instead of through the Play Store, so Android and Play Protect cannot recognise the publisher. That is expected for this build. Tap More details, then Install anyway.
Does it work without internet?
Yes for recording: your position, speed and lean are logged offline. Map tiles, route planning, group rides and the voice room need a connection.
What does it share during a group ride?
Your name, bike, role, live position, speed and heading, plus messages and hazards, and only while you are in that ride. Emergency contacts and your medical details are never sent. Voice is not recorded or stored.
Will it drain my battery?
Recording uses GPS and motion sensors, as any ride tracker does. Keep the phone charging on long rides and exclude RevCrank from battery optimisation so it can run with the screen off.
Is crash detection a guarantee?
No. It is an aid that can fail or give false alarms. Always ride with proper gear, keep your emergency contacts up to date, and try the drill mode in Settings to see how it behaves.
Is there an iPhone version?
Not yet. This preview is Android only (Android 7 or newer).
