The output from this app said it is fine and no problem detected. I hoped to be able to compare results before and after i install acoustic panels. ### 1/5 — Was great: now broken? *2022-10-18, version 2.2.1* After working very well, I went to use it today and it plays static and then a high pitched tone, which means it then never has silence to measure the reverb. I deleted and uninstalled, and it still did it. :( ### 1/5 — Crashes every time I try to record *2022-06-08, version 2.2.1* Keeps crashing when I click record. I read the previous review and followed all the developer’s instructions about uninstalling and reinstalling the app. App doesn’t appear to have been updated in the last two years. Running iOS 15.5 on an iPhone 11 Pro ### 4/5 — Works for me but I don’t know if it is accurate *2022-05-09, version 2.2.1* Works for me but I don’t know if it is accurate ### 1/5 — Wow *2022-04-14, version 2.2.1* Bruh this won’t recognize me clapping ### 1/5 — Bug *2020-11-08, version 2.2.1* Bug, envoie des ultra sons et ne fonctionne pas correctement ### 3/5 — Upgrading to three stars. Showing promise but still broken. *2020-03-04, version 2.2* I had rated this 1 star, because it wouldn’t even run. The developer updated, and asked me to try it again. Now it runs, sort of. I tried it twice, and it ran once (with a bug in the keyboard), but the second time I ran it, it crashed. To the developer: showing promise! What I saw of it working, looks great! Measures background noise for baseline, then takes five samples, all autodetecting the noise event. Critical issue: my iOS alarm (apple alarm clock app) went off while using your app, and the app totally crashed. Non-critical (but highly annoying) issue: When trying to save data, the iOS keyboard was directly over the fields I needed to type in. I couldn’t see what I was typing. If it matters, I use a slightly “zoomed” iOS keyboard. Not hugely zoomed, but enough for my eyesight at age 45. ### 1/5 — Doesn’t work *2019-12-17, version 2.1* Crashes when I press Record (iOS 13, iPhone 8) ### 1/5 — Needs more testing *2019-12-03* Doesn’t work on iPhone 11 Pro Max **Developer response:** Hi JontyLP , Update 2022-12-13, the app works well now, would you consider change your note please? Thanks. Update 2021-10-09, the app works well now, would you consider change your note please? Thanks. The app crashed since iOS 13 release. It is now solved with the version 2.2! Would you consider testing the updated app and changing your review? Thank you very much. Alexis from Atelier 7hz ### 5/5 — Awesome! *2018-11-30, version 1.0* Very useful and promising app. Good to know that the app will be updated with new features! ## Most critical reviews (10 lowest-rated) ### 1/5 — Bug *2025-04-20, version 2.3.1* Téléchargé le 20/04/25 : iPhone 15, IOS 18.4 : l’application quitte presque à chaque essai lorsqu’on touche le bouton « calculer ». ### 1/5 — It's a shame. *2024-05-15, version 2.2.3* Good looking app, but it's not working. After the compute button is pressed it shuts down. ### 1/5 — Won’t work *2024-01-04, version 2.2.3* Won’t work on Apple ISO 17 ### 1/5 — Useless app *2023-07-29, version 2.2.3* Only thing I got from this is some sore hands from claping. Doesn’t work. Don’t waste your time on this one. Not even any troubleshooting options to try and figure out why it failed so miserably. ### 1/5 — Doesn’t wait for claps *2023-01-01, version 2.2.2* Creates distortion noise out of speaker, rendering app useless. Does not work. ### 1/5 — Bug *2022-11-23, version 2.2.1* Idem que le commentaire précédent. J’ai désinstallé et reinstallé, sur iPhone 12. Je lance la mesure de bruit de fond et plus rien ne se passe. J’ai également le même phénomène de Larsen avant de lancer la mesure de BdF. ### 1/5 — iOS 16 incompatibility *2022-11-13, version 2.2.1* Does not work with iOS 16 ### 1/5 — Doesn’t work with iOS16 *2022-11-05, version 2.2.1* Worked fine in iOS15 on a 13MaxPro. Stopped working after update to iOS16. Pity, it was a useful app. ### 1/5 — Just doesn’t work… *2022-11-03, version 2.2.1* Being stuck on background noise measurement… ### 1/5 — Crying shame *2022-10-21, version 2.2.1* Very simply, this was a great app, such a shame that it now crashes on slightly older devices and simply doesn't work (stays on measuring background noise) on latest OS. Any chance of a fix and update, please? ## Most praised reviews (10 highest-rated) ### 5/5 — Thanks for the update *2025-03-25, version 2.3.0* Ça fait plaisir de savoir que l'application est toujours développée! ### 5/5 — Great App ! *2025-03-17, version 2.2.3* Incredible results ### 5/5 — iP15P *2024-01-01, version 2.2.3* Very helpful app. ### 5/5 — Parfait ! *2023-12-31, version 2.2.3* Petite application facile à utiliser. Permet de se faire une idée plus précise et surtout plus convaincante vis à vis des tiers que ce qu’on obtient "à l’oreille" : étant musicien, j’ai parfois du mal à faire comprendre l’importance de la réverbération aux "profanes". Effectivement, on a un sifflement au départ, qu’on élimine facilement en baissant le volume. Bravo et merci ! ### 5/5 — Skittles fluff *2022-10-20, version 2.2.1* If you are getting high pitched feedback noise it is because your phones volume is too high. ### 5/5 — Only app that works *2020-07-23, version 2.2.1* I tried 10 apps to measure reverberation time. This was the only one which worked. ### 5/5 — Works for me! *2020-05-13, version 2.2* It does what it is supposed to do, with a clean, non-distracting UI. I like it! ### 5/5 — Très pratique *2020-03-10, version 2.2* Utile pour verifier l’acoustique des salles ### 5/5 — Useful to design reverberation time *2019-01-10, version 1.0* I used it several times and it helps me to quickly assess reverberation time in a room and tell if it’s adequate. ### 5/5 — Good job *2019-01-10, version 1.0* Une des seules applications étant capable de calculer une durée de réverbération proche de la réalité. Good job ! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
