Lean Angle Calculation on the EatSleepRIDE App
Lean and Mean Angle Calculation
The EatSleepRIDE App is as diverse as the motorcycle community that it serves; many people say it's like five apps in one, and everyone is bound to use it differently. The data nerds among us tend to be most interested in getting their ride analytics.
EatSleepRIDE Mobile provides a highly secure platform for riders to record a wide range of data relating to bike performance, fuel economy, personal riding style, routes and locations, including calculating a rider's lean angle.
Lean Angle Calculation
We use internal iOS sensors to calculate a rider's position in relation to the road, which provides the lean angle calculation. Your lean angle is presented on a 180 degree scale: 0 to -90 degrees is your left lean angle. 0 to 90 degrees is your right lean angle.
Calculating Your Lean Angle
If you see a wonky lean angle reading i.e. greater than 90° degrees or -90°, it may be due to an adjustment in the device's position when you're holding it in your hand just before or after your ride. Or maybe you're doing cartwheels on your bike, which we would be very interested in hearing more about.
Where should you keep the iPhone, iPad or iPod Touch to collect accurate readings?
Readings may differ based on where you keep your device; it's important to make sure the device is snug in a spot where it won't be moving around.
Ride Data - EatSleepRIDE Motorcycles App
The most accurate readings have been taken when the device is oriented screen- facing-upwards, lying flat towards the sky in a tank bag. We also achieved some very accurate readings with the device mounted on the handlebars - just make sure you're watching the road.
Riders who subscribe to CrashLight can do either but it's best to keep the device in a breast pocket in the event the rider is separated from the bike in a crash.
How have you been using the lean angle, and what kind of readings are you getting? Let us know in the comment section below.

Thanks for your feedback! We've made improvements to the lean angle in the last few releases to take advantage of Apple's improvements to the compass. Your lean angle is calculated using Apple's built in compass. Apple is working through issues with the compass and it is always improving with every OS, as a result so will the lean angle collection. To allow for maximum reliability, you'll need to cary the iPhone in your pocket, in the vertical position to collect lean angle.
Before you ride, remember to calibrate your compass. To learn more about calibrating the iPhone compass check out this knowledge base post:

I have similar problem with this app. (iPhone 5s) The lean angle calculation dosn't work. Any idea? THX
Lean angle part of GoRide doesn't work. Tried phone both longitudinally and laterally with screen level and face up. Phone (i5s) rigidly mounted with steering stem RAM iphone case kit. Multiple passes same set of curves. Bogus lean angle recording. Tried walking while tilting phone in all combinations of phone orientations. Bogus lean angle in GoRide mode. Any advice? Thanks. Dave
