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

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

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.

I like it

United States

This is really my first experience with an app like this, but I find it is really easy to use and it keeps me motivated and focused. Highly recommend.

Great App, Some drawbacks

Susaybaka on

United States

I love this app so far and it is very convenient. The best parts by far are the timer and rest time features. They help so much with staying on track. The app is very functional without premium to get an idea of how it works without having to get a free trial. But after using it premium is such a great luxury. The one gripe I have with the app is the fact that the social and achievement aspects are so hard to navigate. One thing they could do to really finish this app is to add the muscle group body from arrow, and implement a similar pr focused social and achievement aspect. Love you Flex Fitness!
