Clash after IOS 17
The app was good but started clashing after latest IOS 17 update
Great app all around
Love all these 30 day challenge apps. They are good at progressing you slowly enough that as a beginner I can keep up. You can set reminders to keep you motivated and the REST days are every four days which is perfect.
Great free app with lots of options
Love that it has different levels, and each starts out slow but builds, increasing strength and stamina. Would give it 5 stars if had more options at higher levels, but still a great challenge.
Very good
Just downloaded the app. Seems very easy to use. I will update this review once I get through the challenge
What level?
Difficult to know which level to start at when you are a novice. Slow and steady build up in plank duration which hopefully leads to a good core strength and toned muscles.
