User Reviews

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.

Pros

Well-made, progressive, and easy-to-follow training programs.
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.

Recent reviews

I purchased this app years ago as part of a paid bundle and had full access to the features I paid for. After the latest update, the app no longer recognizes my previous purchases and is now prompting me to subscribe to access content I’ve already bought. I contacted customer support about this issue and never received a reply. I’ve tried restoring my purchases, but the app still fails to acknowledge them. It’s extremely disappointing to see loyal customers treated this way after supporting the app financially from the beginning. Existing customers should not lose access to their legitimate purchases or be pushed into a recurring subscription model to regain what they already paid for. Until previous purchases are honored and support actually responds to customers, I cannot recommend this app. 1 star.

Used to be a free app on the last platform I used now they want you to sign up for premium after 2 weeks and lock the rest.

What I love about all of your other apps is that I feel successful right from the beginning. This one is too difficult from the start and I need to cheat.
