Regular work out apps are laggy or hard to use but this app is very “Apple” with its lay out

App is not showing December 2024. I’ve been using the app to track my workouts and days that I go to the gym but it for some reason stops showing the days after December. What’s going on?

This was by far the most simple,aesthetic,cleanest and best workout app I have ever downloaded and I did not regret it and belive me I have tried over 30 workout apps and this was the best

Gone are the days of Apple notes

Inzzain on

Canada

No more notes app to track my sets reps and weights. Also cool to add people and see friends workouts. It’s not very popular but I hope it catches on so they can add even more workouts to their library. I also hope it catches so they can add a one time purchase instead of a subscription for people who want premium features but don’t care for workout routines and other features that are changing. These were the only things stopping me from giving it 5 stars. I wish they had more body weight exercises and Pilates / callisthenics moves for those of us who like to combine agility, strength, control and flexibility. Great app overall, ◡̈

Exactly what I was looking for

JVeldez on

Canada

I’ve been on a hunt for an app like flex for a while. As a newbie in the gym, I feel so much better using flex as a guide for what to do and how to do it. It’s so easy to use, I love how customizable everything is. The price is very reasonable in my opinion also, highly recommend!

Bad pricing model

scdean on

Canada

The app may be good but I’ll never know. This is advertised in the App Store as Free Lifetime Premium. I downloaded the app and my only choices after a free two week trial were $59.99/year or $4.99/mnth. I decided to try it at $4.99/mnth and when I went to my subscriptions in iOS, I was set up to be billed $59.99 after two weeks. I had the option to change that to $9.99/mnth if I wanted. I have several subscription apps I happily pay for, as long as I’m not being duped. No thanks.
