It still looks like it does, but half of the functions don’t work at all like pink noise (very important), impulse, and white noise. The functions that kinda work have very choppy output (sin wave) making them completely useless. The link to the Google group is dead, so I assume this software is too. ### 2/5 — Please release March 2024: Versions 8.6 *2024-07-12* Please release March 2024: Versions 8.6 that reflects the calibration of Dayton Audio iMM-6C. ### 3/5 — 版本太老了，商店能更新吗？我安卓手机都7.2.3版本了。能不能联系一下我？？实在总不了，能退吗 *2021-02-12* 能退吗？版本太老了。我的安卓手机都7.2.3了，能退掉吗？不能退的得更新呀！！！ ### 3/5 — Display issue with iPhone 6s *2016-01-17* When rotating from portrait to landscape the menus below the graph become a blank grey box and stay that way. In order to get the menu bar to come back, you have to close the app and reopen. But, once you tilt the phone the problem starts all over again. **Developer response:** This problem, reported by some users, was fixed in the latest release, 5.6.16. ### 3/5 — Loved this app but. *2015-05-30* I have loved this app and use it a lot. But. Now when I turn my iPad sideways (landscape) the app still thinks it's upright (portrait). I lose several bars of frequency. And the bars are out of range high. Worked fine mid May 2015. Must have been an update? I think it was a downdate. **Developer response:** This problem, reported by some users, was fixed in the latest release, 5.6.16. ## Most critical reviews (10 lowest-rated) ### 1/5 — Signal generator is broken *2026-07-27* Pink noise does not work. ### 1/5 — RTA funciona porem Gerador pink e white não *2023-03-20* Muito a melhorar ainda ### 1/5 — No running Pink & White Noise *2022-12-13* Pink noise and white noise do not work on ipad and iphone. Please test properly. ### 1/5 — Why doesn't the function work after ios16? *2022-12-13* Why doesn't the function work after ios16? My MacBook is not recognizing my microphone. Only generators work. ### 1/5 — Unusable *2022-11-11* Does not work anymore!!! **Developer response:** Latest version fixes problems in iOS16. ### 1/5 — Problem Solving *2022-09-30* The app isn't working Please let the update fix the problem! ### 1/5 — 老版本 *2021-05-24* 能不能更新下，现在这个东西需求量挺大的 ### 1/5 — Ver 5.6.16 review *2019-07-17* I purchased this I hoped it would outperform a free Rt60 app I downloaded. Well not really. The file save function doesn’t work. Neither does the show/hide feature for rt60 results. I looked at the user manual online and the interface at the web site given doesn’t match what I got on the iPhone version. I am using it on iPhone 6s. Don’t expect it the menu options or file functionality to work as expected. ### 1/5 — Useless thus far *2016-09-29* Looks like an abandoned app see January review it's now approaching October Graybar no interface nowhere the tap Etc **Developer response:** This problem, reported by some users, was fixed in the latest release, 5.6.16. ### 1/5 — Broken Rip Off *2016-05-17* This app does not work - do not buy it. Give me my money back!!!!! Fraud! ## Most praised reviews (10 highest-rated) ### 5/5 — Working now! *2022-12-08* Thanks for the update. It’s now working on my iPhone (iOS 16.1.2) ### 5/5 — Good *2020-05-13* Used it when I was on Android. Was happy to find it when I moved to iOS. Still one of the most full featured audio apps. Great for a quick reference as a sound engineer or production manager. I recommend having pro grade tools, but this is a good quick reference tool. ### 5/5 — Peerless! "Quick and Dirty" Amatuer App *2015-09-26* This app stands head and shoulders above every other audio measurement suite in the App Store, and the fact that it is free ought to shame all other producers into "upping their game". Making no claims to be a professional grade app, it nonetheless delivers every tool and measurement needed to produce the "quick and dirty" audio measurements you need, and these can only be improved on with staggering investments in tools, in time (for measurements) and in expertise (for analysis). Anyone interested in seeing what audio analysis is capable of can produce outstanding results with this app ALONE! ### 5/5 — Best bang for buck *2015-08-11* Support is great. This app is a total bargain for everything it does. Does the same thing, if not more, than analyzer apps that cost much, much more. ### 5/5 — I almost blew $75 bucks. *2014-03-11* I am astonished at what a mere $2.99 buys you! You could charge ten times that or more! I am using this to A/B test some audio gear, very interesting so far. Keep up good work! ### 5/5 — Essential *2014-02-05* Comforting to have a tool like this close to hand, and an absolute steal at £1.99. I'd never expect perfect instrumentation from a mobile device but this app performs well and gives consistent results. A must have for any audio engineer out in the field ### 5/5 — Great tools *2014-01-02* I looked for and found a great spectrum analyser in iAudioTool. Fast, easy and intuitive it gives me a very useful readout of essential data for sound checks and shows. Also has weightings and averaging and all runs fluidly on my iPad next to my mixer control apps. There's also a good forum where the developer is involved and reacts to comments positively. An excellent purchase for a professional engineer. ### 4/5 — iPhone CarPlay audio issue, otherwise great app! *2021-10-22* On my 8 Plus using CarPlay (via Lightning connector), no sound from the app. When I manually change the output (using AirPlay routing icon in Control Center) it plays blips of sound and clicks but nothing steady. This sound anomaly continues when put back to “iPhone,” which routes audio to the earpiece, but it won’t act normal again until app is force quit. I was trying to use it to RTA my car stereo which only has CarPlay and BlueTooth (haven’t tried BT connection yet). Please advise? Thanks! ### 4/5 — RT60测试 *2015-06-17* 这个测试出来的表格显示的带宽响应是时间还是Q值 ### 3/5 — Change in 16. *2022-10-18* The app worked fine until I upgraded to iOS 16. Now the app does not give any indication that it is receiving any audio. **Developer response:** Latest version fixes problems in iOS16. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
