  1. [R5] ProFit 4/5 · US Options: Wouldn’t be nice if you can include options and we’re doing sets of four. I just hit an add which would repeat the set automatically adding the same weight and reps so I do not have to do independently for everyone. It also would be nice if there’s a place where you could keep notes to see if it was a difficult or easy set and if you had a substitute because not all the gyms have the same
  2. [R12] ProFit 3/5 · US Not a personal app: I downloaded this and went through the setup. The exercises look descent but the major issue is that they have the one size fits all mentality. During the setup I was hoping it asks me my age, sex, height, current weight and target weight, etc.… so that it can provide me with a “personalized” plan. But it didn’t. I understand all the arguments about the privacy issues and al
  3. [R14] ProFit 5/5 · US Excelente: Súper!!!! Para principiante hasta avanzado paso a paso, la mejor app 💪🏻
  4. [R21] ProFit 3/5 · US Bro what: It expects me to be a full on body builder day one bro i’m 12 and 60 pounds HOW DO I DO A REVERSE PUSH UP
  5. [R10] ProFit 1/5 · US Username Not Found: When I go to sign in, I’m met with “Username Not Found.” The app was able to accept my payment information, yet not load my username. Can’t get in touch with anyone for help.
  6. [R18] ProFit 3/5 · US The app is not working: The app is amazing but now it’s not working now. It pops up the plan modal when I click any buttons and I’m unable to access the free pages.
  7. [R32] ProFit 4/5 · US Good Plans, Easy to Use: This app is a good start for people who are looking to get into working out or back into it. It takes all the hard work of putting together good workout plans and just lets you get straight to business! For the developers, you should make each days workout accessible from the locked screen to update weight and reps and each workout for that day. It would make things easi
  8. [R34] ProFit 5/5 · US I’m married to this app!: I’ve been using it for two years. It tells you exactly which part of the muscle you’re training, and HOW to do it correctly, on video. The best!

  10. [R6] ProFit 3/5 · US Bru: I literally have to pay $20 just to work out and 50 dollars for 3 months 🤦
  11. [R7] ProFit 1/5 · US No free trial: Atleast give one month free trial so we can check if you plan is working or not so we can pay for next month. Without testing why would we pay for subscription. Also why would be pay you 20$ per month if physical trainer on gym in Pakistan is charging only 5$
  12. [R9] ProFit 3/5 · US Price: Price I’d too high for a basic workout plan, everybody’s in this to get rich

  14. [R22] ProFit 1/5 · US No la recomiendo: Esta app es una estafa , cobra la subscripcion y entras creyendo que tendrás acceso a todo por 29.99 y no al entrar te das cuenta que para ver los entrenamientos debes pagar otra cuota anual , en pocas palabras de nada te sirve pagar la subscripcion, para mí esto es una estafa .

  19. [R89] Muscle Booster Workout Tracker 5/5 · US Get this app!!!: I absolutely love this app and the workouts it builds for me. I’m giving it five stars but if there’s one thing that I would want to change, it would only be that I’d be able to track the weights amount I’m lifting on each workout to track how much stronger I’m getting overtime. I’m 10 weeks in and I can’t wait to see the improvements I make over the next year.
