Note: Current app version uses English locale (i.e. it uses a dot as a decimal separator) even if you choose a non-English locale (i.e. one that uses a comma as a decimal separator).

Tablet-capable! App tested on Nexus 7 and Android 4.4.2 Kit Kat.

Great app....easy to use. The adjustable slider in the cadence window is so useful. Great tool overall with a clean UI. Highly recommended to any fixed wheel enthusiast and/or high performance athlete.

Arguably the best, but it has lost the ability to provide roll-out (development) in metres, making it unusable without additional conversion.

What's new

v.1.27 Bug-fix on v.1.25. Thanks to Rhysiart. Apologies for the frequent updates today.

v.1.26 Ensured app can run on Android Donut 1.6 instead of just Honeycomb 3.0.

v.1.25 Increased max. cadence to 200rpm after seeing proof it could be done!

v.1.24 Updated to provide content rating. Fixed force-close bug when using non-English locale. Successfully tested under Android 3.0 Honeycomb emulator (one issue: skid patches image is upside down).
