Does the app work reliably on Android? low
Some recent users report significant technical issues on Android, including the app not starting, freezing on the loading screen, and missing audio/video for exercises. However, this is based on a small sample of negative reviews and may not represent the experience of all Android users.
Source: user_reviews
Can I cancel my subscription without being charged? low
Reviews from late 2025 and early 2026 report that automatic renewals resulted in charges even when users believed they had canceled, particularly when the app was not working. It is advisable to cancel through the app store (Google Play) and confirm cancellation, rather than relying solely on in-app options.
Source: user_reviews
Does the app work for gym workouts with full equipment? low
The app description says you can create custom plans based on your equipment, including free weights and machines. However, one recent user reported that even with a 'full gym' selected, the app gave too many bodyweight exercises with no way to adjust this.
Source: user_reviews, app_metadata
What age groups is the app suitable for? low
The app is rated 'Everyone' on Google Play. One positive recent review from a 72-year-old user praised it for creating age-appropriate mobility and weight workouts. The app's customization allows users to enter their age, fitness level, and health conditions.

How this content was created
Content type: pattern_analysis_of_user_reviews_and_metadata
AI generated: Yes
- Google Play user reviews (5 out of a preferred 12-20. The sample is significantly smaller than optimal. per app), November 2025 to March 2026
- Google Play ratings distribution
- App Store listing metadata
- Review samples are not statistically representative of all user sentiment.
- All claims are based on a single bucket (recent_reviews) with only 5 reviews, as the other sampling buckets were empty. This significantly limits confidence in all findings.
- Claims labeled 'low confidence' are based on single-review observations and should be treated with caution.
- No real-world app testing was conducted.
- Feature availability may vary by region, device, and app version.
- The ratings_distribution was null, so sentiment balance could not be verified against lifetime data.

5★I am a 72yo man who needed to transition to a workout routine that was more appropriate for my age. This app has helped tremendously with that; by providing very specific mobility and weight workouts consistent with my new age appropriate goals. The app is easy to use, is very specific and keeps track of your progress. It also allows feedback for exercise routines, which can then adjust your routine for difficulty, pain etc. The routines are also very time efficient, making schedules easier.

1★STOP!! Won't work on my Android. Before you subscribe review the many other fitness apps. Even though you can cancel monthly renewals, they intend to KEEP whatever you initially pay, even if the app doesn't work on your device. chair tai chi shows elapsed time & no audio or video. waste of money and time. I'm got junk email subscriptions I never requested immediately after confirming my account. They did reach out and offer help but nothing they suggested worked. I don't recommend this app.

2★Originally got this app because tired of unavailable machines at gym and needed new motivation. Had it for ~1 year, used 3-4 times / month. Got rid of it due to technical issues in past month that wouldn't be corrected: for new-to-me exercises, sound files that announce the exercise and number of repetitions would not annunciate -- worked fine for exercises I'd done since the beginning but not the newer exercises. Support wants screenshot/video even if told "LOOK HERE!" so not worth it

3★I really wanted to like this app, and I do! But I canceled within days of purchasing because of two serious flaws: 1) there is no bicep selection, which is crazy, and 2) you can put in that you have a full gym and it still gives you more body weight exercises than anything and there is no way to turn it off. It is cool how quickly and easily the app makes a workout for you, but it's not worth anything if it consistently gives you something you aren't interested in.

1★The app wont work. At all. I had forgotten about the subscription because I never got to use the app in the first place and got charged $96 when it did an automatic renewal I thought I had canceled because the app is useless. Stuck on the very first loading screen. And it's been like that since I first downloaded it. Complete waste of my money. I could have just saved that total of $130ish dollars for something that either actually worked or something more important.
