I can’t use the app, because my iOS is 15.7 and flex requires iOS 16 or higher

O melhor

cnandalima on

Brazil

Não tem como, esse aqui é 10/10! Completo demais, e a versão premium é PERFEITA!

Parece ser bom

Feelliipe on

Brazil

O aplicativo parecer ser bom, o motivo de 3 estrela é porque ele poderia ser melhor tem muitos exercícios bons premium que poderia ser de graça e o pior é que ele é todo em inglês poderia ter versão em português porque nem todos sabem falar inglês ou tem uma base do inglês, fora isso o aplicativo em bom

I’ve been using it for over a month and it’s the best

Torres, Pedro H. on

Brazil

As title says, I’ve been using it for over a month now and it is truly the best free workout app that I’ve ever tried. The paid option is also very good but if you won’t feel scammed into using the paid version unless you want to. The free version has everything you will ever need.

Opções de idioma

Brazil

o app é muito bom, mas totalmente em inglês é isso dificulta bastante para quem não é fluente (eu sou uma delas)

Aplicativo ótimo

Sarah Gonzaga on

Brazil

Um ótimo aplicativo, mas poderia haver a opção de escolher o idioma, o aplicativo é todo em inglês e eu por exemplo que não sou fluente tenho muita dificuldade!!!

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
