Malheureusement depuis la mise à jour iOS, impossible de sauvegarder quoique ce soit. ### 4/5 — Infinity instruments *2020-08-16* I like the app, but i think i would like it more, if you could have infinity instruments. And everytime, i try to record a song, the app crashes ### 1/5 — What the hell doesn’t work?? *2019-12-06* Guess I gotta report as fraud. Dont work ### 1/5 — Crashing upon opening!! *2019-11-20* This app is broken on the iPad, it will immediately close down after opening it. It seems to work fine on the iPhone, but it needs an update to prevent it crashing on the iPad. I’m using an iPad Pro 2 11” ### 1/5 — Do not buy for iPad Pro 2018 unsupported *2019-11-10* Well I was stupid reading reviews after I installed Rotor.(sigh)I was just ready to play. I realized there have been no updates in a year, fails to load. No response from the developer after several emails. ### 1/5 — Won’t Open ???? *2019-10-26* Won’t open on my tablet ? I’ve sent you several messages, but you won’t reply ? I’ve tried deleting and reinstalling it, but with no luck. I wanted to buy the contraptions that go with it but there’s no point now. What a shame ! Either reply and help me or give me a refund? I am so disappointed ! ### 1/5 — Not updated for iOS 13... last update > 1 year ago *2019-10-03* ... but when it worked, it was great ### 1/5 — Incompatible avec iOS 13 *2019-10-01* Payé plein pot et incompatible sur mon iPad Pro iOS 13 .... Vite une mise à jour Merci ### 1/5 — Not working on iPad Pro 2 - ios13.1 *2019-09-29* Can you please fix ASAP ### 1/5 — Does Not Start on iPAD Air (2019) *2019-06-28* Instantly Crashes on iPAD AIR (2019) with iOS 12.3.1 ### 1/5 — Crashes on start *2019-05-10* Just purchased. iPad Pro 11 inch. Current operating system. Crashes immediately after opening. Tried restarting. No luck. Help. ### 1/5 — Crashes on iOS 12 *2019-02-10* Duuuude I spent 12 bucks and it doesn’t run on iPad Pro iOS 12 Please fix this! Can I get a refund? ### 1/5 — Никакого юзабилити и глюки *2019-01-19* Уйма бесполезных кнопок и функций. Пользоваться совершенно неудобно. В ютубе и на сайте сплошная реклама, ничего не поймешь. Вылетает без сохранения. Отсутствуют настройки midi out. Модули, как выяснилось, все-таки удаляются перемещением за экран. Но количество модулей ограничено (не мудрено, потому что система в принципе нерациональная). Деньги не возвращают. ### 1/5 — Stürzt sofort ab!!! *2019-01-03* Habe die se App für das iPad Pro gekauft, Doch leider lässt sie sich nicht mal öffnen. Das ist dann doch etwas viel Geld für ein Icon auf dem Display. Bitte updaten !!!!!! ### 2/5 — Absturz nach Start *2018-12-17* Konnte die App nicht testen, da diese sofort nach dem Start abstürzt. Selbst nach Neusinstallation. Verwende ein iPad Pro 2018 und das neuste iOS. ## Most critical reviews (10 lowest-rated) ### 1/5 — why are you still selling this? *2022-09-15* its a brilliant app that is useless now: crashes upon saving, a problem its had for years. **Developer response:** Hi, we are working on a new version that will fix it. You will get it very soon. ### 1/5 — Can not save! *2021-01-24* Please fix the bug. I can not save a session. I think it is sorry. ### 1/5 — 終わってた。 *2020-12-14* 見かけほど可能性を感じず放って置いたが、 久々に触ってみたら、保存すらできなくなってた。 コントローラも買ったのになぁ。 盛り上がってた自分、反省… iPad Pro 10.5-inch ios13.5 ### 1/5 — 无法进入 *2020-10-10* 刚下载才看到不能用，开发商赶快更新呀 ### 1/5 — Just crashes *2020-09-16* desperately need update, or you just lost all your works! **Developer response:** Thank you for noticing. We will update and fix the app as soon as possible. ### 1/5 — Incompatible *2020-08-26* Ne fonctionne pas sur iPad Pro .pourquoi ?mise à jour obligatoire.12eur pour rien. ### 1/5 — 更新了系统，软件不能用了哎 *2020-08-25* 系统。。。 ### 1/5 — New iPad Pro doesn’t work *2020-07-13* I’ve used reactable’s earlier app on an old iPad 2 for years. I held off on rotor until I had a more powerful device. Now that I have an new iPad Pro I have this $19 dollar app that doesn’t work. Or only that no tangible knobs available. Don’t get it. I want my money back. ### 1/5 — I love this app, but now it only crashes when trying to access my projects *2020-02-13* This app was great in the beginning, I would build patches on the go. Now however, when I open, it only loads the last project, if I try to save or navigate to my other projects, it crashes. Disappointed because I have songs built on here that I hadn’t exported yet. Be careful when creating in this app, be sure to export any patches you make to something outside the app. ### 1/5 — Crashes on startup (iPad Pro) *2020-01-11* Downloaded Rotor for my iPad Pro and it crashes on startup. Hard restarts/delete & reinstalls —nothing’s worked. Not a good start for the app intended for iPad Pro! Fix this or refund me ASAP! ## Most praised reviews (10 highest-rated) ### 5/5 — Keep working on it *2025-10-16* Amazing idea, please keep working on it and have tutorials for dummies. Also fix the saving part. ### 5/5 — It's been 2 years *2020-09-07* Very cool app that obviously took a ton of hard work to develop. Why did you go to sleep for 2 years? I guess you gave up. Too bad because you could have evolved it or created a new version that had different controls if people didn't like this one. You guys are great developers. Why give up. ### 5/5 — Nice tool *2019-06-07* I enjoy this app really. It is quite easy to control and almost better than playing stupid games!!! ### 5/5 — Great Music Creation Tool *2019-04-01* I have been with this app from the beginning and in this version it’s massive it has it all a very creative way of creating your music a must have if you love to experiment with your creative process. ### 5/5 — Still crashes on iPhone 8 :-/ *2018-08-10* Last update told issue was fixed. Again: Update please. Update: works just fine now. So 5 Stars for iPhone Version too. 5 Stars for iPad Version. **Developer response:** Sorry for the inconvenience, since we don't have these devices we only tested in the iPhone simulator supplied by Apple, but seems that the bug can only be replicated in the actual devices. We are working on a fix and will submit an update as soon as we can identify the problem. ### 5/5 — Fun Creative Quality *2018-06-02* This is a long term app for making music and sketching ideas. And it is fun. Super creative idea that most iOS music makers should enjoy. I love it! ### 5/5 — Great modular DAW *2018-04-27* Very creative tool ... I use it for generative Ambient and Glitch Sound. A lot of fun to use Rotor. You can get deep in it and create unusual sounds. ### 5/5 — Music Synthesis Playground *2018-02-25* I love this app. I’ve bought countless synth and sequencer apps over the years, but this one really stands out. The developers have produced an app which is hugely flexible, is fun to use, looks impressive and sounds great. I hope they will continue to develop it, because it has great potential. More parameters for the synths and please increase the number of modules! The manual and tutorials are excellent. ### 5/5 — Update *2018-01-05* Well that update fixed it and I love the response time and update notes! **Developer response:** Have you tested our new version? this should fix the issues in your iPhone 8 ### 5/5 — Great Music Making App *2017-03-18* Rotor is a terrific upgrade from Reactable Mobile. MIDI, IAA, Audiobus, Audiocopy/AudioShare and so many other features are available in Rotor. For example, you can record loops and then load the recorded audio into a different sample player. Moreover, you can load various beats, sequences and loops created from different projects and have them synchronized to the same tempo and playing back in the same key. Ableton Link allows Rotor to play nice with other music apps. Overall, just a great job by the developers of bringing to the masses an IOS experience that feels much closer to what it is like to play a real Reactable! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
