## Review summary

The app is praised for its well-made, progressive training and effectiveness in building pull-up strength, plus the overall quality of Zen Labs apps. However, multiple reviews highlight a forced subscription after updates, loss of previously purchased content, frequent bugs, and a poor beginner onboarding experience that makes starting the program confusing.

- Adaptive/customizable workouts that fit your fitness level.
- Proven effectiveness at increasing pull-ups and achieving milestones.
- Quality Zen Labs ecosystem with consistent app quality across the suite.

### Cons

- Forced subscription after updates and lockout of features with poor grandfathering.
- Loss of access to previously purchased content after updates.
- Technical bugs: crashes, timer issues, and timers not running in the background as needed.
- Difficult beginner onboarding: initial week too hard and unclear where to start.
