Road Bike Power Meter – Test Ride West of Oshkosh, Wisconsin

Road bike power meter app test ride for Cykelstrom version 1.30 which is available to the public on the Google Play Store. Version 1.30 changes the app displayed averages at the end of the ride for moving time only. To make better use of the limited resources on some smartphones, improvements were made to GPS data collection threads and fine tuning of the power estimate calculations.

I made some updates to the power calculation algorithm, in addition I made the averages displayed at the end of the ride to represent only moving time. If you take a long water break, your down time is not represented in the averages.
