Great workouts, but some malfunctioning features

There a great number of workouts available for all muscle groups. Recording the activities within the app works well. Instructions are reliable for each workout. There are also exercises for resistance bands and dumbbells.

Automatic sync has never worked with Argus, which is a sister app that records steps, and syncs with other fitness applications. I have to manually sync every time or the activity is not recorded within Argus.

I have tried their premium plans which must be paid for, but they continually get stuck on an individual days workout and do not progress. I have changed phones, deleted and reinstalled the app, reset the workout schedule and contacted customer service to no avail.

They had offered to extend my subscription, but I just received an email from Apple saying that it was about to end at its original expiration. Im sure its just a mixup between the two companies, but what is the point on continuing a subscription plan that is stuck on day 7? I am trying a new app, but will keep the more basic version of Instant Fitness for the workouts.
