I’d welcome an update, but doubt it will come. ### 3/5 — Темный фон *2023-01-16, version 4.0* В Dark режиме, часть функций на экране не видна, белое пустое поле ### 3/5 — Great app what happened *2021-03-28, version 4.0* I used this app for years it’s great, I recently upgraded my phone and the app, now when I use the tone generator the box to enter the desired frequency is gone!! What happened that’s so greatly needed ### 5/5 — Update needed *2021-02-06, version 4.0* Great tool but calibration needs to be updated for newer iPads like iPad Air 4. ### 4/5 — Dark mode bugs *2020-12-31, version 4.0* Great app, useful tools but can’t use the wave tables or see text in parts of the app since updated to using dark mode on iOS. ### 1/5 — Calibration file not available for iPhone 12?? *2020-12-16, version 4.0* Was excited to try this sound app. However... Calibration file not available for iPhone 12?? ### 4/5 — Bit buggy *2020-11-28, version 4.0* Bit buggy with dark mode enabled in iPad system settings ### 3/5 — Dark mode *2020-10-20, version 4.0* I can't see anything on dark mode. ### 1/5 — сломали все ..... *2020-10-08, version 4.0* пропал доступ к настройкам ### 4/5 — Excellent Tool *2020-10-07, version 4.0* I use the Noise Generator app on my iPhone connected to the PA system in conjunction with the RTA app on my iPad to ring out a room (fine tune the Graphic EQ).
