No useful documentation/manual. *2026-07-02* Do you like puzzles? Then you’ll love this app!🧩 The available documentation is perpetually out of date and inaccurate, and the in-app help is useless. Even if the documentation was accurate, it’s often not very forthcoming on details. Dev just keeps piling on more features and never documents. Just absolute negligence of a one-man shop. It’s really too bad, because it looks to offer a lot of great features that I would love to use in making music. But I am done guessing how to make it work. I truly don’t often give one-star reviews, but this has earned it 🏆 ### 5/5 — Phenomenal App. Sequencer🔥 *2026-05-03* While using the app I didn’t think I would love it as much as I do but it’s absolutely so good. I highly recommend it to anyone starting or trying to perfect their craft. Been using this app for a while now and decided to finally give a honest review how great this app is. Great Job 👏🏼 ### 3/5 — Requires deep dive *2026-02-13* Make it more clear what each thing can do. If it can’t be made clear, then take it out. RFM does not help. Make a lite version for idiots like me. ### 5/5 — Peerless *2025-12-30* Centerpiece-level powerhouse. This artful sequencer stands out for its combination of a near-perfect touch interface with the depth and control of a great hardware unit. Reading and watching the manual is mandatory because of Prism’s unintuitive (not counterintuitive) interface, but spending a few months coming to grips with the beautiful, visionary design language and the co-functionality of the individual modules will be rewarded with a sense of refined fluency and deliberate control which stands above the fiddly, bulging translations of PC workflows which are ubiquitous in this environment. No other app that I’ve used marries this level of harmonically cohesive compositional complexity to a total elimination of prickly, insufficient touch interactions. This production paradigm is especially unparalleled on iPhone, but the core concept is worthwhile in any MIDI sequencing context. Rare bugs and quirks typical of an app in relatively early development are not nearly enough to knock Prism out of first place. ### 5/5 — Auv3 *2025-12-03, version 2.01* Cubasis adaptive please! ### 5/5 — Amazing App, Erm Lots of Updates *2025-11-19* The sequencer is amazing, when it was released it was perfect, the new features are nice, but please remember you can do multiple apps. At this point I fear this thing is on the verge of getting bloated, it’s starting to take a little more tapping to get to where I want to be sometimes now ### 5/5 — From Eno To Aphex *2025-11-08* The new LFO, FX, and multi-seq extensions are awesome, and half the price of what you would pay for similar standalone apps. Prism was already inspiring and high-end. Now it’s the GOAT iOs sequencer too. Well done. ### 2/5 — Разочарован *2025-11-07, version 2.0* Покупал на старте в надежде на развитие, на улучшение, на дополнительные функции… Ну, встречайте, вот оно развитие - этот с виду добрый и миловидный разработчик вначале задрал цену на своё приложение (ну как бы в целом норм и когда уже есть, это вообще не важно), но и добавил кучу встроенных покупок, так же не дешевых причем уже на старте. Само приложение не интуитивное, хоть и симпатичное, нужно изучить кучу туториала на ютубе. Раз несколько пытался вникнуть, разобраться, но видимо не хватает усидчивости, постоянно злишься из-за того, что что-то не понимаешь и невозможно сразу найти ответ на свой вопрос, приходится терять кучу времени на просмотр видео. А теперь ещё и встроенные покупки…. Короче остается пожелать этому товарищу ничего хорошего от своей жадности, ну впрочем он скоро и сам это поймет. ### 5/5 — Inspired and brilliant *2025-09-23* Every time I use this app, I get great results, even with very limited abilities. It makes me feel very inspired and I’m fascinated with getting deeper into it - every time I level up it gets more fun. I have a *lot* of iOS sequencers and for whatever reason I keep coming back to Prism again and again, and I’m never bored or uncreative when I’m in it. Great support from the developer too - he fixed bugs quickly and answered all questions and was really energized. ### 5/5 — So good *2025-05-30, version 1.0709* I am really enjoying this Midi sequencer! I don’t think I’ve seen anything like this in hardware ever, some features are so inventive and inspiring. Took a little while to understand how the interface worked but so worth the effort, so much fun to be had on this thing. Both in AUM but also plug into your DAW of choice or hardware and this thing becomes even more. Well done and thank you to the developer 👏🙏🏻 ## Frequently asked questions about Prism MIDI Sequencer ### What does Prism MIDI Sequencer do?
