This app seems very informative and looked like a good tool to help me along. Love the detail it provides on the major and minor muscles. Was really looking forward to diving into a more detailed and concentrated work out. Unfortunately, the app crashes when I try to scroll workout suggestions. Frustrating. ### 2/5 — App used to work *2026-02-16, version 4.0* App was great when it worked but it now will only stay open 20 seconds before it shuts down. Do not pay for this app, waste of $$ ### 2/5 — Amazing app! But now it’s glitching… *2026-02-15, version 4.0* Recently when I find a muscle and start to scroll through the stretches or exercises, the app closes completely. I can spin the body, subtract or add layers but once I slide through the actions - it kicks me out. IOS. iPhone 15. PLEASE fix this!!! I really… LOVE this app so much. Not only does it give me a deeper knowledge of my muscular structure, it gives me ways to strengthen and relax areas in pain or that are weak. This is a resource that everyone should have access to. I hope the developers maintain care to this app that provides so much to others. Thank you for creating it! I hope it becomes functional soon or another app becomes available. ### 2/5 — Keeps crashing *2026-02-13, version 4.0* App looks good but keeps crashing so can’t use it properly ### 2/5 — Crashes no longer able to use *2026-02-12, version 4.0* I really loved this app until I recently updated it in December. Now it constantly crashes. I am so disappointed. I spoke to the company. I’m still waiting for them to fix the app. I would really appreciate if they could fix the app for all the people who already purchased it. Thank you ### 4/5 — Hasn’t been update for a while, crashes with latest IOS *2026-02-12, version 4.0* Really miss this app. Cant use, crashes with latest iOS.

Hugely disappointing ### 1/5 — BUG *2026-02-19, version 4.0* The app keep kicking me out !!!! ### 1/5 — App crashing *2026-02-19, version 4.0* Recently have noticed the app keep crashing, is there a resolution for the same by the developer? ### 1/5 — App closes out *2026-02-18, version 4.0* Why does this app close out anytime you try to scroll across and see the exercises for a specific muscle? I just paid $4.00 and this is what I get? Pathetic!!! ### 1/5 — Unusable *2026-02-16, version 4.0* This app keeps closing on its own. Literally closes within seconds of opening. So frustrating! ### 1/5 — Keeps crashing *2026-02-16, version 4.0* Willing to change rating if issue is fixed, but I’m a bit miffed that I paid for a useless app ### 1/5 — Keeps Crashing *2026-02-16, version 4.0* *****NEEDS BUG FIX for specific muscle group when clicking on it for exercise ### 1/5 — Can’t explore the app without crashing *2026-02-13, version 4.0* I’ve had this app on my previous iPhone 8 and loved this app. I’ve since upgraded to an iPhone 13 and when I try to target specific muscle groups to learn what exercises are most effective, the app crashes, without fail, every time. Pretty much paid to look at a human muscle model lol. If there’s any way to fix or update this please let me know. ### 1/5 — App Crashes After Five Seconds *2026-02-12, version 4.0* App keeps crashing when I use the model feature. Cool app otherwise. I hope it gets fixed. ### 1/5 — My imucle 2 is failing! It open but it is closing after 3 seconds *2026-02-11, version 4.0* What is happening?? I paid to have this app for ever!! But now it is closing after 3 seconds after I open.. I can’t reach the exercises! I’m so disappointed ## Most praised reviews (10 highest-rated) ### 5/5 — Stopped working! *2026-02-20, version 4.0* It was great for a few years! But then it just closes randomly these days. What a loss. ### 5/5 — Still having bug issues *2026-02-11, version 4.0* It’s a great app when it doesn’t shutdown 30second after opening ### 5/5 — Great, wish there was more deep muscles *2026-02-03, version 4.0* So the app is really really good. I just wish that they were more like deep small muscles, especially in the buttocks, like the obturators, the gemellus. Those are abstracted away; you see a hollow space in the buttocks. It would have been amazing for people that have injuries there to have also access to those exercises. Same for facial muscles; it would be great if we could also click on them so we could get granularity. I'd be willing to pay extra for those. ### 5/5 — Glitch in app *2026-01-31, version 4.0* As mentioned by others, the app is great but lately it has been closing on its own every time I across across to exercise choices. It obviously needs attention. ### 5/5 — Great app *2026-01-11, version 4.0* As a massage therapist, I use this app frequently to send my clients stretches or strengthening exercises to target specific muscles as a part of their treatment plan. The moving muscle man is extremely helpful so my clients know they are executing the stretches/exercises properly. Update 1.10.2026 Keeps crashing, more than usual. iPhone 15 ### 5/5 — Imuscle2 *2025-12-12, version 4.0* A great App ### 5/5 — Workout *2025-12-10, version 4.0* When I'm stuck on an exercise the app helps me to break through the fog. ### 5/5 — User friendly *2025-08-21, version 4.0* As a personal trainer it is the best tool easy to use and rasure to tech to use ### 5/5 — Great app *2025-07-10, version 4.0* Love this app it helps me get to where the problem is fantastic ### 5/5 — Gives view into how muscles are structured *2025-06-09, version 4.0* And provides exercises to help keep them in shape --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
