Really slow

XxVadxX01 on

Australia

I was in the middle of a timer and it just crashed on me. Was working perfectly fine before, other than that it’s a great app.

Awesome app

JackyBoio on

Australia

Needed a new app to record my burnt calories, easy and adjustable to aid me in mu weight loss

Changed the app

Gabe2480 on

Australia

It was a good app before they changed it. Now so glitchy and terrible to use. Wasted of $90

set up workouts from a computer

The Flex app is a great application, I use it daily. It would be a really great addition if there was a way for a user to set up your workouts and training schedule using an online browser or using an M1 M2 Mac to allow is ease of use

I KEEP GETTING CHARGED

I cancelled my subscription yesterday was due to expire today, yet I was charged $90 this is a joke.

Not a free app

MissieSk on

United States

The app promotes that it’s free but much of the content is available only through a paid subscription. You can search online for workout routines and create your own workout which is rather handy

I 🩵 It

didiacorn on

United States

I admire the widget because it allows me to see what I have planned for the day without opening the app, I recently just updated the app and found a whole new adjustments and changes that I immediately heavily fell in love with. • I like how I can add a certain workout to any day, whether its biweekly, weekly, etc. • I love the gym community so this is pretty much my comfort spot, and I love how much people are sharing their progress! • And I like when I'm done creating a workout for some other day, It's based on an estimate on how many calories I burn, and how long it'll take for me to finish that workout. I love this Workout overall, it's helped me watch my calorie burning, steps taking, and shows me how to correctly do a couple of workouts that I haven't done before.

Very fun

ianl212 on

Very easy to use. My favorite workout tracker. I love the 1 rep max calculator and rankings against other users. Super fun

Almost great

Brinkmanc on

United States

I was so excited to use this app but after a few weeks, I canceled my subscription. It has a beautiful design and I love that you can create custom exercises but the plate calculator and AI progression are very glitchy and not working properly. This app may be great if they fix glitches but for now, I’ll stick with Alpha Progression.

Good for detailed tracking

wakeup2 on

United States

Great for saving workouts whether these are cardio, calisthenics, or strength training. The app has a bank of exercises to choose from and if needed, you can create custom ones. You can group exercises into supersets and set rest times between reps. Also, if competition and point systems motivate you to exercise, then this app is for you! You earn points for every workout and can unlock achievements for more points. If you really want to unleash your competitiveness, view the rankings. It’ll really humble you. I left off a star because it’d be more convenient if I could add workouts anytime like the MyFitness App, which allows you to manually fill out the date and time for any previous day. I like this because sometimes I forget to track workouts and this app (at least the free version) doesn’t allow you to add a workout to a previous day.
