WattDr

WattDr connects to multiple bike power meters and provides an easy way to compare the current and average watts. You can record the data and export it in JSON format. 

Existing health and fitness apps were designed for regular workouts. WattDr is designed for cyclist that want to know how their power meters compare to each other and have a desire to understand the differences in detail. The data export includes accurate millisecond timestamps for each power meter reading.
