WaoStats

A desktop application to analyse and archive your Wahoo ELEMNT bike computer tracks. It runs on macOS, Windows and Linux.

view your Wahoo computer firmware versions, used sensors and their battery status (when track ended)
plot the recorded values (altitude, speed, cadence, temperature, grade, heartrate, power, battery, calories, L/R balance, gears, gear ratio, gps accuracy) from your FIT files, over time or over distance
link your tracks to your used devices (bikes) and see total kilometers per device
dropbox sync your FIT files
ADB (USB) sync your FIT files directly from your Wahoo bike computer
display your track on 16 different maps (google, openstreetmap, bing and more)
load GPX tracks into the application with reduced statistics (compared to FIT)
log service activities and get service reminders

Enter app key and app secret to WaoStats dropbox menu.
