I don’t normally buy apps but this is definitely recommended for value for money! I used this app in particular for my studies but I continue to use it daily, alongside the other apps, to enhance my knowledge.

In den letzten Jahren sind mehr und mehr Bugs aufgetreten. Neulich habe ich festgestellt, dass die kurzen Clips / Animationen unter „Media“ nicht mehr abrufbar sind - das ist wirklich sehr schade. Ich hoffe auf baldigen Fix - dann gibts auch 5 Sterne ### 3/5 — Не работает видео *2021-02-21* На iPhone 8+ не работает видео! ### 2/5 — Media video missing *2021-02-06* The media for seeing rotations is missing. Can you fix this please ### 4/5 — 아이폰에서 머슬 액션이 안나오네요 *2021-01-08* 잘되다가 머슬 액션 자채가 구동이 되질 안되네요 3년전 업데이트 이후에 업데이트가 이루어지질 않네요 ### 3/5 — Видео *2020-10-15* Скажите пожалуйста,почему не работает видео? Это приложение было на iPhone 8 все прекрасно работала,сменил на iPhone 8+ не работает. ### 2/5 — Useful but annoying *2020-05-07* I have used the title of another review as I completely agree. This app is useful; the muscle diagrams are clear enough. However, you can’t move the diagrams all that much. For anyone who has used Essential Anatomy or Complete Anatomy the range of movement that is possible is subpar. Spend the extra money on Essential Anatomy 5; much more bang for your buck. I deleted this app shortly after purchasing it and bought essential anatomy instead. ### 2/5 — Needs improvement *2019-12-26* I thought it would give you better access to the muscles. You actually need to look up on a list the muscle to see it. It would be nice to touch the muscle on the full body view, have it zoom in to it and give you the pin to click for information. When you look for the muscle on the list it does this cool effect that removes the layers of muscles covering the one you want to see. But as soon as you move it you lose the information pin that shows up at first. I think there should be a way to turn it on or off. Like the hints on how to zoom in or out. I like the graphics and the information of the muscles, but it would be nice to have more control of what you want to see. Thank you. ### 3/5 — 不能360旋转 *2018-11-07* 不能旋转 白买了 ### 3/5 — Space 🐷 *2018-06-17* Pros: detail info for every muscle including O/I, nervation, action (with video); clear graphics; able to add your own notes Cons: can be slow to load; takes a huge amount of space on the iPhone, only updated every couple years - I feel with more development/updates it could be more efficient. ### 3/5 — Great app but *2018-04-09* I’ve bought an iPad so I can see it bigger on the screen but it’s asking me to spend £9.99. I already own the app so can’t understand why I would need to but it again. Could anyone help? Many thanks. ### 5/5 — I can’t say enough good things *2017-09-26* I am a Physical Therapist. I have been using the muscle and skeletal app since my iPhone4 to explain to my patients what is going on in their body. I literally use these two apps every day and have gotten more complements from patients on their greater understanding of their condition due to these. I have been stressing the last two days without it due to the IOS update. Thank you for getting this out. It is my life line at work!!! ## Most critical reviews (10 lowest-rated) ### 1/5 — The media comes up as black on my phone *2021-03-28* I invested in this specifically to see the functions of each of the muscles and really liked that this app apparently had a demonstration portion. But when I click on Media, it just comes up as a black picture and no demonstration. I just paid money for this and I’m not happy about it ### 1/5 — Ужасно *2021-03-07* Не функциональное, видео не работают, приложение не удобно в использовании. За что я заплатил Деньги ? Отмените покупку, хочу вернуть деньги. Смысл этого приложения ? ### 1/5 — Not working *2021-02-09, version 3.8.1* The 3D media screen is not working!! ### 1/5 — Is this thing on? *2021-02-02, version 3.8.1* I’m a PTA. I’ve loved this app for years and recommend it frequently to other professionals. However it has started crashing before it opens and I can’t reach tech support. What’s going on? ### 1/5 — Error *2020-12-25* video does not load as muscles contract ### 1/5 — Student *2018-09-26, version 3.8.1* I did not like it the display is not HD and it loads slow hard to pinpoint muscles ### 1/5 — Not supported by iOS update!!! *2017-09-22, version 3.8* I updated my iPhone and now can’t use this app. PLEASE UPDATE THE APP TO BE COMPATIBLE WITH THE CURRENT iOS VERSION!!! ### 1/5 — IOS 11??? *2017-09-19* Where is the update??? ### 1/5 — Incompatible with iOS 11 *2017-08-01, version 3.8* Purchased the app just to find out that it is not compatible with the up-to-date iOS. A total waste of money... Folks, we need an update! Your app is being recommended for those who are taking a personal trainer certification course... ### 1/5 — Do not buy if you have an updated iOS! *2017-07-28* I was happy with essential anatomy but this app is junk and shouldn't be sold if it's not compatible with newer iOS. Waste of money and makes me weary of making future purchases ## Most praised reviews (10 highest-rated) ### 5/5 — Very detailed and helpful app *2026-03-15* Great resource for studying anatomy. I’ve had this app for years and still refer to it for help with identifying muscles, bony prominences, etc. It’s definitely worth checking it out. ### 5/5 — Outstanding app *2023-01-30* This is so easy to use with great information. When I was in massage school it was my to go app. I didn’t have to use my textbook all the time when I need quick information. I recommend this app to everyone. ### 5/5 — Great reference *2023-01-26* Outstanding ### 5/5 — If People Like This Why Stop? *2021-05-14* The developer says this will be the last update to reassess where to assign resources. Are they assessing correctly? I argue they could use professional input! ### 5/5 — The App Media doesn’t work *2021-05-02* This App has been fantastic for a long time. But now suddenly the media section where it shows the movement of the muscles no longer work. Disappointed... ### 5/5 — Update *2021-01-27* Please update this app. I cannot see the media for what the muscles do!! Help!! ### 5/5 — Fantastic *2021-01-25* An absolute life saver in my anatomy studies when I’m struggling to find something that the text books just don’t depict well enough ### 5/5 — Update... *2020-11-24* Now Can’t open App in IOS 14. Plz update.. ### 5/5 — PT Tool *2019-07-19* The app is a great tool as a PT working with clients doing rehab. I love it. ### 5/5 — Brilliant app. Loved it. *2018-11-02* I have been using this app since 2012 (UK store) on iPhone 4. Then on 5s, now on 6s. Looks and works perfect. Loads faster compared to other anatomy apps. You need to be more precise in clicking to get the right response. Keep up. Planning on iPad as well so that it’s easy for my patients to understand while explaining the muscle involvement during pain management. Good work guys. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
