Buggy and frustrating.
Fails to open most of the time even after reboots (cold and hard). Lots of ads even in the pro version. Annoyingly small buttons are hard to press with gloves on. If you dont click done after your run your day is forgotten. No statistics about your running pace or encouragement to maintain a pace.
