Why does it keep on crashing? Deleted and re installed, now lost years of history. Have used app for years but now just unusable, please fix 😡😡 ### 3/5 — 2026 IPAD AIR M3 isses *2026-02-21, version 4.0* It’s been awhile since I’ve used this app. It’s one of my favorites. I just tried adding workouts and when I add the 3rd exercise it closes and will not save. I hope an update comes soon. Normally I would give it a 5 star. ### 3/5 — Not bad at all *2026-02-16, version 4.0* Can someone help me with the app, it always colapse in my IPad and IPhone once I tryed to swipe right more exercies mi racha group ### 1/5 — Crashing app *2026-02-08, version 4.0* I really liked this app and have used it often. Recently I tried using the app and it keeps crashing and I’ve tried everything to get it to work and it keeps crashing. It’s lame cause I paid for the app and now it doesn’t work. ### 1/5 — App keeps crashing and now unusable *2026-02-06, version 4.0* This app used to be great but for some reason it now keeps crashing after a minute or so of use on my ipad. Uninstalled, re-installed - same problem. Unable to contact ‘App support’ as safari can’t open the webpage (‘the URL doesn’t exist”). Having paid for this app I’ll be asking for a refund unless it’s sorted very soon. ### 3/5 — App crashes *2026-01-30, version 4.0* Great app in principle but too many crashes. Scrolling through exercises via model generates a crash every single time - why has this not been addressed? ### 1/5 — crash *2026-01-18, version 4.0* unusable ### 2/5 — Crashes! Constantly *2026-01-05, version 4.0* My workout will cause it to crash. ### 2/5 — Still Maintained?? Crashes *2025-12-16* This is actually an outstanding app that I've used for more than 10 years. Sadly, ever since iOS 26.1 and 26.2 (iPad), it crashes every time I try to edit or create a new workout. Some of the old features are also missing. I'm now looking for a replacement, but I'm not sure this can be replaced. I would gladly pay a fee to keep it going. ## Frequently asked questions about iMuscle 2 ### What does iMuscle 2 do? iMuscle 2 is a 3D-based health and fitness application designed to help users plan and track their fitness programs.
