Only issue I have is that it doesn’t seem to support full screen on my iPad when it in landscape mode. Am I missing something? ### 3/5 — 아하… *2024-02-08* 마이크 소리에 따른 비주얼라이져인지 몰랐네요… ### 4/5 — Simple but *2019-11-08* How about a threshold adjustment? I don’t want to turn down mic but I want it to settle out between songs. I like it while music is playing but it’s still jumping all over between songs. Love the bars but I’d also like to adjust width. Keep up the good work. I’d love to see an Apple TV version. Currently I’m mirroring my iPad. Thanks ### 2/5 — iPad Pro 11 Update? *2019-05-09* Bitte iPad Pro 11 Display Unterstützung, dann gibts 5 Sterne. ### 4/5 — Does what it says *2019-04-28* This is a great example of a simple app that does exactly what it says it will. Brilliant. ### 4/5 — Unbelievably great... just 1 attachment! *2019-02-16* I really like how this app has different visualisers, but I was wondering if we could like... put a background, I rated it 4 stars at the moment but I’ll rate it 5 stars if you could just add backgrounds. Thank you for reading, have a good day! ### 3/5 — Cant use with Bluetooth *2019-01-21* Its a decent app very nice... but you cannot connect to Bluetooth items and use the led screen which defeats the whole purpose for my use, and this app cost money, so a waste for me unless this is fixed. That would be very helpful thank you ### 4/5 — Great app. *2018-02-09, version 2.9.1* Like how it moves with the beat of the music but noticed that the mic compressor kicks in and drops the level down when the music gets a little loud. Other than that great app! ### 3/5 — Fix it! *2017-08-19, version 2.9.1* Keeps crashing. ### 1/5 — Warning! Do Not Buy. *2017-07-31, version 2.9.1* This review is very simple. Doesn't work! Got Ripped Off! ### 4/5 — Good app, satisfied. *2017-01-27, version 2.9.1* To make it a 5 star it should IMO have more visualizer options. ## Most critical reviews (10 lowest-rated) ### 1/5 — Disappointed *2025-10-23* Not very many options or variations ### 1/5 — Cuts off airplay music when app is activated. *2022-12-31* Like the title says. Airplay music gets cut out when this app is activated. ### 1/5 — Need blue tooth connectivity *2021-01-10* App is great exactly what I am looking for but useless without connectivity. I would gladly bay $20 more if it had connectivity **Developer response:** Hi John,  This is a technical limitation and is out of our control.  As stated on the app store description and screenshots: "Currently Bluetooth is *not* supported. The app uses internal microphone and speakers only. Do not download if Bluetooth is required."  With any issues please contact us directly at apps@onyx3.com. You can also request a refund if the app is of no use for you. ### 1/5 — Doesn’t work *2018-11-18, version 2.9.1* This app looks cool, but all it does is immediately crash when I try to open it. Lame ### 1/5 — Crap *2018-11-18, version 2.9.1* AVOID!!!! Last update 3 years ago. Even then there was Bluetooth. That took my money, (me stupid). DO NOT GIVE THEM YOURS. Continue your day, I have it is great. ### 1/5 — Jordan *2018-10-09* Some of the apps are crashing and Kicking me off ### 1/5 — Bluetooth incompatible *2018-10-04, version 2.9.1* Disconnects Bluetooth speaker when open. ### 1/5 — No Bluetooth *2018-09-08* Bought this so I could use it in the car whilst Bluetoothing my music. Once the app is loaded the Bluetooth link goes off. So as far as I’m concerned this app is waste of money. ### 1/5 — 💥 *2018-06-14, version 2.9.1* Crashes right when I open it!!!!!!!!!!!!!!!!!!!!!!! ### 1/5 — Doesn't work with Bluetooth *2018-01-09, version 2.9.1* I wanted to download this app to give me an old-school feel in my car. I remember in the 90s I had a graphic equalizer with the display lights. For some reason this app disables Bluetooth when listening to music. Did not work for my purposes. ## Most praised reviews (10 highest-rated) ### 5/5 — Best app *2025-12-26* Unbeatable ### 5/5 — Love this app ! *2022-10-07* Time party ! In space and time to go boldly we’re no mind has gone. ### 5/5 — Loved it :) *2022-02-14, version 2.9.3* Just what I was looking for ! Worth £2.50 in my eyes ! I Would like to be able to change the colour of falling top bricks ( red ) ! Just like the old school spectrum. ! Love it & very impressed :) ### 5/5 — Works wonderfully with the new iPad Mini *2019-11-09* It’s a nice app, the graphics are elegant and very satisfying! An unique visual upgrade for any sound system. Works flawlessly with the new iPad Mini . Worth every penny! Recommend! ### 5/5 — Best Visualizer *2019-10-01* I have been looking for something simple that works with all my Music!! Finally found 1. This is Great and Inexpensive!! Thank You ### 5/5 — Very good visual app *2019-09-03* Looks great and very sensitive to microphone’s sounds. Please consider making this app bluetooth compatible! ### 5/5 — Отличное приложение *2018-11-21* Спасибо за обновление! Отличное приложение! Использую через повтор экрана и Apple TV на большом экране телевизора как цветомузыку из 90-х ### 5/5 — Brilliant *2018-09-20* Exactly what I wanted - an iPhone app displaying a vintage hifi style spectrum analyser I could cast on my tv via Apple TV. This works brilliantly and mic settings are sensitive enough to pick up most of the spectrum and fill the screen. Good job! ### 5/5 — Fun, visually interesting *2018-09-06* It’s curious as that as I show this to different people… Either they get it or they don’t 😳. If you like flashing lights and things that go beep and give you a visual feedback, this is a fun app and really mimics hardware-based visualizers that cost far more than this app cost to license. Check it out... 👍🏼😁 ### 5/5 — Awesome *2015-12-19, version 2.9.1* This is exactly what I was looking for. Great job... --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
