The best exercise app

Hi onyx team
I am Amirhomayoon , from Iran.
I use your app for about a week and that is fabulous! Perfect! Its just like a trainer train you. The ranking and voice motivate me so much! I wants to thank you due to making this perfect app in this hard situation in corona that we cant go to gym and workouts outside . The only thing that is not good for us is the price of pro version, in Iran this prices are very high because of bad economical situations here. Also if we have money we can’t pay for it , because there isn’t any visa or master card here.. only local banks. So please help me so i can enjoy and use your app more and more in this corona pandemic.
Thank you so much

I really wanted to love this app

I really wanted to love this app! While we’re isolating in the midst of COVID, it seems like a dream to have a trainer give you real-time feedback about your form. I did a couple of workouts during the one-week trial and then signed up for the annual subscription. Unfortunately as I started using the app more, I found the tracking functionality to be poor. It would simply not track my movements and when you are physically pushing yourself to the limits, it’s beyond frustrating to not have your exercises tracked. I contacted customer service, who replied promptly and was very nice, but he gave me like six different things I had to do to make the tracking feature work (be inside, not too close, not too far, pull up your hair, don’t let other people in and out of the frame, etc), all of which are not super easy to do when you are trapped in a house with your family and pets. I tried again with all the guidance and still, app wasn’t tracking my movements. Sooo frustrating.
I was less than a month into my subscription and requested to cancel my subscription and get a pro-rated discount for the remaining 11 months. Sadly for me, the very nice customer service rep says that’s an apple thing and out of his control. Bummer, I’m out the money for an entire year.
I love the concept of this app, but am super disappointed that I have paid a full year for essentially a beta product.

The app has tons of potential but lacks workouts

This app is exactly what I was looking for. The ability to track my movements, the fact that it tells you when your form needs adjustment, the reminders and ability to track workouts including how well you do them is awesome. HOWEVER, the amount of workouts and programs available is very limited. I’m the kind of person that gets bored of workouts aren’t continually changing. I would go through all of them in about 4 months. Half that if I wants starting from beginning level. And even less than that if I wanted to workout for more than 10/15 minutes per workout. I wish there was a monthly membership or the promise that the company was going to keep adding workouts to make the yearly or lifetime membership worth it. It’s a good option for people who don’t mind doing the same thing over and over over again.

Developer Response ,

Thank you for your review.

We plan to release 50+ new exercises in the fall including a larger number of ab, upper body, and cardio exercises, as well as dozens of new workouts from our trainers.

We hope this answers your concern.
