Since the low noise rumble around 50 Hz is pretty loud in the old building, an optional low cut for a custom frequency often would be of help. Alternatively a custom frequency window with a from-to-Hz range would be another solution to just watch and record a pre-defined range within the spectrum. Dear developer, thank you very much for your great work. **Developer response:** Thank you for your nice comment😊 As you said, there are vibrations and hum noises caused by the AC power line and its harmonics. A long time ago, Japan first introduced AC generators from Germany, so Eastern Japan is 50Hz and Western Japan is 60Hz! ### 5/5 — Analyser *2024-12-08* Hallo, der Spektrum Analyser hat unsere Heinzungssgeräusche bestätigt. Das störende Geräusch ist wohl eine Pumpe 7 Etagen unter uns. Brummt mit Netzfrequenz 50 Hz. **Developer response:** Ich bin froh, dass die App hilfreich war！ ### 5/5 — Help *2024-12-05, version 2.1.12* My neighbour is using a scrambler / jammer on my camera, was told to get this to identify that what is true, any help will do, not technically savvy so would love to get some points on what to buy and do 👍🏻 ### 5/5 — Спасибо! *2024-12-04* Работает прекрасно! **Developer response:** пожалуйста!!!! ### 5/5 — Thanks *2024-11-18, version 2.1.12* Really was helpful in testing my Meditation Music Hz for Authenticity Thankful for all your time and all your efforts regarding our shared interest ### 5/5 — Honestly good *2024-11-06, version 2.1.12* Haven’t seen a single add. This tool even measures your current gravitational force in g’s. the number of tools on this app plus the add free nature and the straightforward design. A baby could use this thing and they measure up to 20000. That’s 4000 more than most and why I’m keeping this. ### 5/5 — Молодец *2024-10-14* Большое спасибо за столько полезное приложение! **Developer response:** пожалуйста☺️ ### 5/5 — Solved our feedback problem is minutes *2024-10-12, version 2.1.11* How good is this app?

Immense respect aux développeur. **Developer response:** Nous sommes vraiment désolés pour l'évaluation excessive ! Nous savons tous que ce n'est pas une application unique et parfaite. Le code source est publié sur github 😢 ### 5/5 — Great app! Great Developer *2024-10-07, version 2.1.9* I used this app frequently and I am appreciative that the developer is so responsive! ### 5/5 — thanks for making this *2024-10-07* Very handy app, thank you! **Developer response:** Thank you so much! ### 5/5 — Way better than the paid-only alternative *2024-10-03, version 2.1.8* I had a trial version of a paid app. The free version of this app is way better! ### 5/5 — Simple, easy, effective *2024-10-03, version 2.1.8* The app has a simple interface is easy to use and does what it is designed to do.

I have no idea how to make it work. ### 1/5 — Abandoned app *2025-06-12, version 2.1.12* A major problem is that due to the small size and close placement of the noise playback buttons, I can't easily work with the app. Additionally, there are no indicators next to the buttons to show, for example, if the color changes, so I can tell if my hand is correctly on the intended button and if the noise is playing or not. Another program that is abandoned and has bugs. ### 1/5 — No explain *2024-08-17, version 2.1.6* Other apps stop working when this app is turned on ### 1/5 — I hate this game *2023-09-23, version 2.1.6* This game has cmarshals and it is so not fun I Don’t know why ### 1/5 — Registers nothing *2023-08-27, version 2.1.6* Who knew it was so quiet in here ### 1/5 — Disappointed *2023-07-21, version 2.1.6* Stop begging for reviews. It’s pathetic. ### 1/5 — En Arabe *2022-05-01* Uniquement en Arabe, inutilisable **Developer response:** i haven’t received the error as such so far. please make sure the settings of Language and Region of your device. ### 1/5 — Can’t get it to measure my motorbike revs *2021-07-11, version 2.1.2* It may be me, but I’m struggling to get it to measure the revs of my single-cylinder motorbike. If developers see this, can you advise? Or is this not what it’s supposed to do? ### 1/5 — No vale *2019-04-27* Está en chino ### 2/5 — Frustrating *2023-12-04, version 2.1.6* Wish you could change scales ## Most praised reviews (10 highest-rated) ### 5/5 — The only one that worked (and free!) *2026-02-06, version 2.1.12* Thank you so much. Excellent app. I do wish it was easier to figure out how to catch the decimal point in frequency, but either way, literally the best of all of them after trying five or six. ### 5/5 — Je l'adore *2025-11-02, version 2.1.12* Cette application est vraiment pratique pour ce lui qui cherche une alternative au produits très dispendieux comme Smaart et pour un homme qui commence dans le domaine des ingénieurs en sono et en FOH !!! ### 5/5 — Amazing *2025-10-15, version 2.1.12* In trying to isolate a high-pitched hum in my home, this app helped me find the frequencies using the FFT and wave generator. Great app! ### 5/5 — Wow *2025-09-04, version 2.1.12* Franchement wow , très bonne App pour IPhone , sans publicité et fonctionnalités performantes. C’est très bien de voir cette App qui est une exception dans nôtre monde capitaliste commercial. Félicitations pour vôtre beau travail de création ne changer rien. Merci ### 5/5 — Amazing and free! *2025-08-10, version 2.1.12* I’ve used this in a variety of live sound environments, and it has been such a helpful tool for quick EQing and room correction. Is there a calibration tool for the mic or is it dependent on the factory calibration of the iPhone’s microphone? ### 5/5 — Amazing app! *2025-06-12* This letter of appreciation goes to the amazing Japanese developer who has made this app. I have no real use for this other than I am a curious person who finds such things interesting.
