  1. [R2] Hevy 5/5 · US Easy peasy: I love how you can easily add exercises and sets to track in the log. It’s very user intuitive. The interface can be mastered by a child. This is important on workout day because the last thing I wanna do is spend time on my phone and not get my pump on!
  2. [R3] Hevy 5/5 · US Great app: Been using it for over a year. Really love it! Easy to build workouts and track them.

  4. [R18] Hevy 5/5 · US Simple: Most apps try to sell you all those stupid gimmicks… Hevy just does what you need it to do and that’s that. Could use some more recognized exercises but besides that 3 dollars a month is sweet.
  5. [R4] Hevy 5/5 · US Sick App: If I can make a comparison, it is the Strava of workout apps. Super easy to use and enables me to track everything I need (weight, reps, exercises) all for free. I’m sure the subscription has great perks but I’m content with the basic free version!

  12. [R55] Hevy 4/5 · US Great app, kills your battery: This app is great and has the perfect amount of free features. You can have 4 plans, which is perfect for my 4 day split. You can easily add sets and change your weights. It is easy to reorder or switch out an exercise as well. With that being said, it kills my battery. I had a 1 hour workout and my battery was drained 19% from this app, yet it was only on the screen
  13. [R5] Hevy 5/5 · US BEST APP EVER!!: I love this app, is the perfect free app to organize your workouts.

I use it with my boyfriend and we are constantly checking what each of use worked out and the pics we posted with it!! The free
  14. [R20] Hevy 5/5 · US Best workout partner: Whether just starting out or a fitness expert, this app is the best workout tool ever. So easy to use and the social aspect is a fun plus but not necessary if you’d rather not partake. Was using free version which is great, but upgraded to add workouts and because it’s that awesome.
  15. [R21] Hevy 5/5 · US Hevy Review: Just hit my 400th workout on HEVY! Highly recommend this app, it makes tracking weight a lot easier. It’s also a nice way to see what your friends are up to in the gym. Go HEVY or go home!

  17. [R16] Hevy 5/5 · US Amazing workout app: Very clean UI and tracks metrics with your Apple Watch. Best part is the huge library of workouts AND how to do them! Also being able to track your sets and put notes! Likely going to upgrade to premium.
  18. [R22] Hevy 5/5 · US Game changing app: Excellent 3d demonstration combined with an easy and comprehensive way to track progress will completely transform your workout.
  19. [R32] Hevy 5/5 · US Best Weightlifting App: I have been trying to get back in the gym and take care of my health. This app has helped me do that. Other apps weren’t helpful enough and trying to keep track of stuff on my own was cumbersome. This app is beginner friendly and gives some helpful advanced metrics. I highly recommend this app!
  20. [R61] Muscle Booster Workout Tracker 1/5 · US Workout: I like some of the workouts but there seems to be a lot of repetition. I don’t like how you can’t go back and see a workout if you missed it. I also don’t want to pay $20 a month.
  21. [R63] Muscle Booster Workout Tracker 3/5 · US Questionable Billing practices: This app avoids the Apple subscription service and bills you directly through a website. We canceled this and we’re still billed for a month service. We were told that we were. ‘Eligible’ for a refund even though we canceled. It’s clear why they are avoiding Apple subscription service. My bank even flagged this as fraudulent. I would consider strongly before subscr
  22. [R94] Muscle Booster Workout Tracker 1/5 · US SCAM: Never signed up for monthly membership. Downloaded app only and it charged me. I've been charged $40 for a monthly fee and have never used it. Contacted them and they WILL NOT ISSUE A REFUND. Never had a company do this. BUYER BEWARE. Plenty of other fitness apps out there, choose one with better customer service.
  23. [R103] Muscle Booster Workout Tracker 1/5 · US Don’t purchase a one week trial they will charge you after the week for a full subscription: Do not purchase
  24. [R19] Hevy 5/5 · US A must for growth: Used to not track my lifts , using this app has shown me my actual gains , and areas of improvement , very motivating to see your numbers increase !
  25. [R76] Muscle Booster Workout Tracker 1/5 · US Shady auto renew scam out of Cyprus.: If you were interested in trying the program for a month to see if it gets results, be aware they automatically charge even if you cancel and do not sign up for auto renew then make refunds very difficult. Shady company out of Cyprus. Do not purchase without being aware/
  26. [R85] Muscle Booster Workout Tracker 1/5 · US Tricky and not good: I tried the app, and didn’t meet my expectations- forgot to cancel, the got charged $38.95 euro which felt abusive since initially it say it’s 14.99 month….be careful
  27. [R91] Muscle Booster Workout Tracker 1/5 · US SCAMMERS: While they may indeed offer some exercises etc they offer zero accountability and make canceling very difficult. Take a photo of when you cancel because you will likely receive another charge the next cycle. And when you cancel that again and contact them the same day as the charge they will refuse a refund, refuse to acknowledge your previous cancellation. Had to get credit card co i
