User Reviews

Most reviews report reliability problems: GPS/distance tracking often fails or is inconsistent; workouts stop or log multiple times when switching apps or after calls, and timing can drop mid-workout. A smaller set of reviews express positive sentiment about the app overall and its gamified badges, but premium subscription controls and limited customization also frustrate users. Overall, the app shows promise but reliability and quality issues are the primary concern across repeat complaints.

Pros

Overall positive sentiment about the app (multiple reviewers say they love it or that it’s a great app).
Gamification elements like badges and challenges that some users appreciate.

Cons

GPS/distance tracking is unreliable or not working, leading to missing distance data.
The app frequently pauses or stops when switching to other apps, answering calls, or playing music.
Workout timing can stop or logs get reset unexpectedly, making logs inaccurate.
Premium/subscription issues, including inability to change training level and difficulty canceling, with slow support.
UI/settings limitations and lack of customization, such as race-date options and settings not scrollable.
