To log activities, you can either:-
sync a wearable (Garmin, Fitbit, Apple Watch, Peloton (via Apple Health), Nike Run Club (via Apple Health), Suunto, Polar, Samsung, Coros, Wahoo), which will then pull across future workouts to GoJoe. Press More > Settings > Applications and devices;
use GoJoe's in-app GPS tracker - press the + button > Record activity; or
manually add the workout - press the + button > Manual activity.
Remember this is about activities, not everyday steps. This means you'll usually have to press start/ stop and save if using a wearable.
