Can someone provide a fix, this is a great workout program but I’d like to track things through this app it just doesn’t even open up ### 3/5 — Great programming, App needs UI/UX help *2021-01-25* Love the workouts, but the app has some interactive aspects that could be improved. No way to lock and finish and workout, so often the app will switch to the previous day in my pocket and then I’m accidentally recording stats over the wrong day. Would be great to finish and record a workout so that to edit it later you have to unlock it or something like other tracking apps. ### 3/5 — Love App and Workout..minor issue *2020-03-27* Hey I love the workout and the availability of the app. It is one of the best workouts I have done, and I’ve done a lot. It is easier to stay motivated with it and it gives measurable results. App Issue: I often need to switch up the workouts in my home gym. When switching the workouts to new ones from the exercise bank, sometimes it replaces everything with the selected workout. This happens to anything highlighted yellow (not sure why they are yellow). So I’ll go through and switch it up before I workout, then I’ll almost be done and I’ll put another workout in and it’ll replace everything with that workout making me have to start over. Hope that makes sense. ### 3/5 — Reps not being submitted *2019-01-06* Love the workouts on the app, but it has an annoying problem when entering the number of reps for each set. The numbers just disappear and it stays blank for some of them. It doesn’t even notify you that you left it blank and then it assumes you entered 0. Would be awesome to get this fixed **Developer response:** I'm sorry to hear about this issue - thank you for making it known to me! I am working on a fix right now and will publish it as soon as possible. Could you please email me at musclehackdeveloper@gmail.com with your iPhone model and any more info you can provide? Then once I publish the fix, I will email you and make sure things are working 100%. ### 4/5 — Good App, but minor issues. *2020-07-02* Been following MuscleHack for several years, and have always enjoyed the information, so decided to switch over to this app from my previous one. I love how simple it is to use, but there are two flaws in my opinion. First, the exercise bank is very limited, however it is nice to be able to write my own in. Second, I always have music playing from my phone via Bluetooth while I workout, and upon opening the app, it lowers the volume quite a bit until after I start and complete the rest timer. Once the timer completes its countdown, the volume returns to normal. Aside from those two issues, I love the app. ### 4/5 — no bs *2018-08-30* This is the best fitness app I’ve seen/used. Very informative and simple to use. ### 5/5 — Changed my life *2021-01-06* As a poor college student, I can’t afford expensive trainers or fitness programs. Mark and MuscleHack have truly changed my life, and I am so grateful for the work that went into this. I will continue to use this app as long as it is free and functional! Thanks again, Mark and Juanito! I donated on your website, hopefully you can continue to maintain the app. ### 5/5 — Dank Workout App *2019-05-14* I absolutely love this dank workout app 💕 ### 5/5 — Perfect! *2019-05-13* Does everything you could want...and it has great default workouts. THT 3-day and 5-day workouts are the best! Easily customizable Still learning new features Been using it every day since December 1 ### 5/5 — Came *2019-04-20* It made me came ## Most praised reviews (4 highest-rated) ### 5/5 — This app is awesome!!! *2019-01-03* I’ve been a fan of Muscle Hack for years, but this app is a game changer!!! ### 5/5 — Developer fixes immediately *2018-12-23* App is phenomenal. Great trainer and great developer. I noticed on the 5 day routine, Mark has dips as chest workouts but the app does not. Is this an oversight or has Mark decided to remove it? **Developer response:** Hello! Thanks for continuing to use MuscleHack on your new phone. I will get on this bug very soon - planning on releasing an update within one week. Thanks for the feedback! EDIT: Would you kindly email me at musclehackdeveloper@gmail.com and let me know what kind of iPhone you have and what version of iOS you are running? I'm running an iPhone 7 on iOS 12.1 and the timer seems to be working fine. ~ Juanito ### 5/5 — It shouldn’t be free *2018-09-03* Great app. Good work son. **Developer response:** Thanks for your awesome review! ~ Juanito ### 5/5 — Good app *2018-08-31* I already work out every day, but still found this app very useful and informative. Can’t beat the price either. **Developer response:** Woohoo! Thanks a bunch! ~ Juanito (developer) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
