Please consider - this would be great to add some background to all sorts of music productions. Update: *Still* looking for Audiobus support, please. SYS would be great for adding organics to beats. There’s an entire Audiobus community that would enjoy this capability. ### 1/5 — This could be interesting-if it ran... *2019-08-21, version 1.08* It crashes on startup, even after a cold reboot of my phone. I’ll try it on my iPad Pro tomorrow, but not holding out too much hope at this stage. ### 1/5 — Open crash, open crash *2019-08-21, version 1.08* That’s all this app does. I open it and it crashes. Cool if you're into that sort of thing. ### 1/5 — One horse sound, then immediate crash. *2019-08-21, version 1.08* This is the sound of failure. ### 3/5 — “Activation failed” *2019-08-21, version 1.08* Update. I did get it to actually work a couple times but for barely a minute each time. And it was pretty awesome. Each time was completely different. Random tones and sound effects and some weird altered or layered speech... Hopefully they get the bugs worked out. ### 1/5 — No idea what this is *2019-08-21, version 1.08* I’m not sure this app is ready for prime time. A lot of wordy hype but not much delivery. It keeps having an authentication error and for an app that eludes to using my speakers and microphone as the input / output mechanism there was no confirmation to allow the app to use the microphone. If it is doing some type of processing what is it processing? Is this just all bells and whistles of randomness wrapped up in an elusive cover? Even the menu items and what actions does the user take are elusive. At this point it seems like a lot of words that don’t deliver anything. Make it friendly and fun and without so many authentication issues and try again. ### 1/5 — SYS Deinit - Shutting Down.::..••.::: *2019-08-20, version 1.08* That’s all this app does, for all its 800MB of glory. SYS(tm) Error - Activation Failed SYS(tm) Deinit - Shutting Down.::..••.::: And instead of developer responding “due to popularity of app, servers cannot handle requests,” just fix it, please. ### 1/5 — Error *2019-08-20, version 1.08* Downloaded app. Keep telling me that says error, activation failed. ### 1/5 — Crashes on opening *2019-08-20, version 1.08* App opens with only a big red logo on the screen sitting there doing nothing. Pressing that also does nothing. No settings menu to setup the app it just does nothing. I hear a short beep in the headphones then the app crashes and closes. Not for prime time only a few reviews almost all bad and from long ago. ### 1/5 — System Error *2019-08-20, version 1.08* Says "system error - shutting down" and closes. That's it. 800 mb download for $10 all for an instant and constant crash. I smell a scam. ### 2/5 — No clue. *2019-08-20, version 1.08* I just downloaded the app. I have no clue how to use it. Do the Headphones or Speakers have to be Bluetooth? Can you use this app with the TV? The app crashes. Please explain in better /simpler details. Thank you. ### 1/5 — Crash Bandicoot *2019-06-20, version 1.06* On boot. ### 1/5 — Sys *2019-06-19, version 1.06* The app exiting after open need to activation ## Most critical reviews (10 lowest-rated) ### 1/5 — Takes up a lot of space and does nothing *2024-05-03, version 2.05* This is one of the biggest wastes of space you can install on an iOS device. Takes up a lot of storage and does a lot of nothing. It has the intelligence of a two week old dead moose. ### 1/5 — Won’t start. *2019-08-28, version 1.08* Really disappointed. Won’t even start. Says activation failed then shuts down. iPhone 8 Plus iOS 12.4 Not sure if I’m missing the point of this app, but it’s noisy for no apparent reason. Can’t find how to turn the sound off. I don’t want that racket on all the time. ### 1/5 — Not working? *2019-08-24, version 1.08* I have not been able to use the app, every time I open it says sys error activation failed. What do I do? Update: developers response is b.s. almost everyone is having a problem, the decision to release this paid app before even getting it to work was bad karma and hopefully apple will address these scams for what they are. I cannot believe they make it sound like our fault that their own computers can not handle the traffic for the app that they created but its o.k. because everyone can tell from using the app to the reviews that they are idiots. ### 1/5 — Are we going backward? *2019-08-22, version 1.08* So let me get this straight: everyone says this is a great app and I guess maybe it was. Before Tuesday. But now that those of us who didn’t have it months ago want to get it, it doesn’t work? Notice that since this week all the comments are complaints? I haven’t been able to get in once. When do you anticipate that you’re going to be able to fix this? Because if this is the state of affairs, then all of us who downloaded it this week should just delete the app so that those people who think it’s “wonderful” can continue to be the only ones to use it. And we can save future prospective users the trouble. ### 1/5 — Started off cool and creepy... *2019-08-22, version 1.08* But since my first time using it, it crashes every time now. 👎👎👎 ### 1/5 — Activation failed *2019-08-21, version 1.08* Shuts down immediately ### 1/5 — Waste of time. *2019-08-21, version 1.08* No wonder it’s free, it doesn’t even start it just shuts down as soon as it runs. ### 1/5 — Let us know... *2019-08-21, version 1.08* Dear developers, Please let us, your would-be users, know when this app can actually be used. It fails to “activate” itself and exits (crashes) which I’m pretty sure is an App Store user experience violation? Thank you ### 1/5 — Crashes before it even starts *2019-08-21, version 1.08* Please could you put in a fix so that this app can be used as it doesn’t even start. Thanks ### 1/5 — Doesn’t work *2019-08-21, version 1.08* Whenever I turn the app on, it immediately shuts down. No wonder it was free. ## Most praised reviews (10 highest-rated) ### 5/5 — 🦢.🐌 *2024-12-09, version 2.05* 🐌❤️‍🔥🐒 ### 5/5 — W484881tm *2019-09-10, version 1.08* The app likes to spit out W484881tm...it’s an interesting phrase 🤣🤣. If you’ve ever heard it, you know what I’m talking about. Also it’s says 666 quite often. All good fun. Love the app ### 5/5 — Insanity *2019-07-01, version 1.06* I still don’t get exactly what if anything I can do to configure the app more than turning it on or if It learns as you go or just starts a fresh every time it’s opened, all in all it’s a great concept and a stepping stone into future tech. ### 5/5 — Cool app ! *2019-06-22, version 1.06* Idk what this app for. Although it quite fun to play with , and do some show-off to my friends too ### 5/5 — Systm is a lot of fun *2019-04-03, version 1.05* Mainvolume has provided a tool to change the world... how will you use it? ### 5/5 — Excellent App! *2019-01-20, version 1.05* A fun and excellent app that really works. Put on the the headphones and enjoy. The future starts right here right now! ### 5/5 — More than a good sys™️ *2018-11-04, version 1.0* How can you not give this a 5 star rating? Enjoy the strange D4T4 loop. ### 4/5 — 4 for now... *2019-08-29, version 1.08* I’d give it 5 if it was compatible with iOS music host apps alike AUM, AB3, Cubasis, etc,. I like to employ random note generators in my music experimenting, so this bizarre app finds a use in my sonic explorations 😑 If only I could... ☝🏽🤩 ### 4/5 — I don’t know what this is, but I love it! *2019-08-20, version 1.08* Ok, I admit that this app is a bit of a mystery for me still, but that’s part of the attraction for me, I think. I really just turn it on...that’s all it seems to do, but when you slip on some headphones and close your eyes, you go into a trippy universe of sounds and words. I’m not even sure if it does more than that? But I love it. I’m really intrigued by the app, and the synthetic sounds it makes are awesome! I can’t wait to see where this app goes in the future, but for now, this app IS the future! Doing research on the developers to see what they’re about. Pretty cool guys, thanks! 👍 ### 4/5 — Crashes *2019-06-24, version 1.06* I can’t get this to load on my iphoneX, crashes every time! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
