Too bad as I found it useful. ### 4/5 — iOS 26.0 ? *2025-09-20, version 2.2.2* Не працює з iOS 26.0 ### 3/5 — Doesn‘t work on iOS 18 *2025-09-18, version 2.2.2* Doesn‘t work on iOS 18 ### 1/5 — App crashing post purchase *2025-09-17* the app never opens and just crashes repeatedly. i did a 1 time purchase and this is happening post that. i need a refund or a working app ### 3/5 — Functionality *2025-06-12, version 2.2.2* Use very long.. apps so nice and very help during due configuration. But my old handphone is gone so the apps were gone. So right now I’m try to install again but need to purchase again. How to restore purchase for this apps with same account.?? Any help or solution to get the pro mode version?? ### 3/5 — Спектр *2025-04-14* Перестал работать после обновления ### 1/5 — Non funziona in altra truffa da pochi euro *2025-04-03, version 2.2.1* Scammer ### 1/5 — Bug sur Spectrum *2025-03-21, version 2.2.1* Once the app is active, it freezes the display. It is no longer possible to use the phone except by turning it off and then turning it back on. Disappointing ### 3/5 — Không dùng được *2025-03-02, version 2.2.1* Tôi mua ứng dụng này nhưng không dùng được. Tính năng RTA hoạt động kém, không nhạy, hiển thị không chính xác ### 1/5 — Not for the uninformed *2025-01-30, version 2.2.1* No guidelines in app, downloaded to make adjustments to my car stereo via the cars EQ settings and through my CarPlay settings. Immediately after the app opened the music coming through my car went completely flat, no explanations on how to use the app, half of the buttons I selected returned an error screen. Can only assume it’s been abandoned by devs or is only for people who know what they are doing already and have it as a third device so you can make tweaks while connected via CarPlay. This is really important in Subarus as non CarPlay music is muddy, tinny and overall terrible due to the OEM head unit. Hopefully I can find something else on the App Store but it was a pretty immediate uninstall ### 2/5 — Refund *2025-01-20, version 2.2.1* It effects the case audio so I can’t use to tune it. It’s been less than 10 minutes can I get a refund or fix my issue please ### 3/5 — No report function *2025-01-01, version 2.2.1* Seems to work fine for "live recording" but as I was planning to use it to demo & compare different Hi-Fi components, a report function (e.g. Showing the full readings across a track) would be necessary, so as to compare performance side by side. ### 1/5 — Funktioniert seit iOS 16 nicht mehr! *2024-12-29, version 2.2.1* Seit iOS 16 werden nur noch Phantasiespektrogramme angezeigt, die nichts mit der Realität zu tun haben. Die Abo Gebühren werden trotzdem abgebucht. Das geht so gar nicht! ### 1/5 — No longer functions. *2024-12-26, version 2.2.1* Dead weight. Paid version. Used to work fine. Doesn’t function at all and crashes now. ## Most critical reviews (10 lowest-rated) ### 1/5 — Не работает *2026-06-18, version 2.3* Не работает приложение, не показывается ни одна кнопка, только фон сиреневый. ### 1/5 — 爛透了 *2026-04-07, version 2.3* 拉 ### 1/5 — Nur kostenpflichtig! *2026-03-21* Laut AppStore angeblich keine InApp-Käufe aber ohne ein Kostenpflichtigen 3-Tages-Test oder Einmalkauf für 8,99 nicht verwendbar! ### 1/5 — Nicht seriös *2026-03-12, version 2.3* Im AppStore wird vorgegaukelt, dass es eine kostenlose Version gibt - totaler Unsinn, bis man die App das erste Mal öffnet: da habe ich die Wahl zwischen Pest und Cholera. Bei solchem Gebaren interessiert mich auch keine 3tägige Testdauer - gleich wieder deinstalliert und in der persönlichen „Blacklist“ notiert. ### 1/5 — >:( *2026-03-10, version 2.3* I, unlike the countless other people who reviewed this, have not liked this app. As far as I’m able to tell, I’m trying to look at waveforms from imported music and that’s impossible. Plus, the cover image? Why? WHY!? I’m a trypophobic person and that thumbnail disturbs me. ### 1/5 — Es de pago *2026-01-08, version 2.3* No pone nada al descargar pero apenas la abres tienes que pagar si quieres usarla. Ni siquiera dan una vez de prueba. Dudo que funcione si van así ### 1/5 — Не работает на iPhone 11. (iOS: 26.1.) *2025-11-29* Не работает на iPhone 11. (iOS: 26.1.) Последняя версия iOS. Пожалуйста решите ошибку. Куплена PRO версия. А приложение не грузится. Пробовал переустанавливать, но не помогло. Буду ждать рабочее приложение. С уважением, Александр. 🤝 ### 1/5 — Took over phone *2025-10-17, version 2.3* App took over phone and offered no way to close. Had to lock, and click on a notification from a different app to get access to anything other than this app. ### 1/5 — Ios26不能用！ *2025-09-29, version 2.2.2* 都付錢了卻在買了新手機以後不能用！ 可以改善嗎？ ### 1/5 — Stopped working *2025-09-28, version 2.2.2* App stopped working after newest iOS update. ## Most praised reviews (10 highest-rated) ### 5/5 — Very good app and free *2026-07-09, version 2.3* Perfect RTA for working out any audio/studio to mix/EQ/stage for the best quality of sound. It’s free, no ads besides a built-in popup every now and then. Very customizable and accurate readings based on multiple FFT size choices ### 5/5 — Fabulous *2025-09-30, version 2.3* Great app. Works a treat! ### 5/5 — Thanks for the iOS 26 fix *2025-09-30, version 2.3* Great app ### 5/5 — Wieder auf dem Stand der Dinge *2025-07-11* Vielen Dank dass ihr den Support für das aktuelle iOS weiter stellt 👍 ### 5/5 — Thank you *2023-06-12, version 2.2.1* This simple App is a nice and helpfull frequency analysator. You normally need to buy expensive software from companies like NI. It would be nice to have dual channel features and some recording functionalities. There is a Bug in cursor mode when you use the spectrogramm. The cursor position X should be time and Y should be frequency ### 5/5 — 卸载了不能再下载了 *2023-01-14* 你好我重新下载不了了要收费 ### 5/5 — Keine Funktion mehr ab iOS 16 *2023-01-01* Seit dem Update auf iOS16 funktioniert keine Messung mehr. Anfragen an den Support blieben unbeantwortet. Vor iOS16 hat die app gut funktioniert. ### 5/5 — 软件工作异常 *2022-11-30* 苹果系统更新后 目前软件出现异常了 ### 5/5 — Parou de funcionar *2022-11-21* Depois da atualizaçao do IOS esse app simplesmente parou de funcionar. ### 5/5 — Does not work in the new Apple iOS 16.1 *2022-10-30, version 2.2.1* Love the app. Purchased it too. Does not work with the latest apple iOS system. Ratz! Hopefully soon! So will rate it a 5 star in hopes it returns! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
