Otherwise super useful for monitor setup in the studio as well as a decent FFT spectrum analyzer which is good for live. ### 1/5 — Needs Update *2024-12-11* Update please. ### 4/5 — It’s 2024 already update the Krk app *2024-04-01* The new Rokit 5th Gen, 3 voice mode should also be operated on the Krk phone app, instead of making use of the function button at the back of the monitors all the time. ### 5/5 — ***** *2024-01-30* Best of this type!!! Лучшее из подобных приложений. ### 1/5 — App abandoned? *2023-12-29, version 1.0* Looks like this app hasn’t seen any updates, several of the top UI elements are blocked or offscreen. Also would be nice to include some suggestions for connecting to the monitors since iPhones haven’t had a headphone jack in quite some time and since a headphone adapter and cables with either XLR or 1/4” TS are required. ### 1/5 — Complete trash *2023-12-11* Doesn’t even make a pink noise sound on the EQ screen, can only get a sound on the level meter. The test button for iOS audio doesn’t even work. Disappointed I spent this money on these monitors excited to use the EQ feature and it doesn’t even work! ### 1/5 — How stupid *2022-09-30* Anyone who would think the mic in an iPhone or iPad could accurately be used for ANY audio measurement shouldn’t be allowed to adjust anything without adult supervision! ### 1/5 — App not optimized for iPhone screen *2021-12-20, version 1.0* Embarrassing app, wouldn’t be able to use it if I didn’t have an iPad. The sound generator is not clickable on an iPhone 12. ### 1/5 — Don’t mine our phone data! *2021-10-09* I’m uninstalling this app until they do there next update and show they aren’t mining peoples data. ## Frequently asked questions about KRK Audio Tools ### What is KRK Audio Tools used for?
