I thought it might help me locate a high pitched sound. Not a chance! Totally confusing and a waste of money! **Developer response:** The app can detect high-frequency sounds (from 8 kHz to 23 kHz) using the iPhone's built-in microphone. In order for this app to work properly, it is necessary to make the microphone access permission settings related to the iOS system. If it is enabled, but it is not working properly, the built-in microphone may be damaged in some way. ### 1/5 — Terrible app *2023-10-04* I tried using it to identify a high pitch noice coming from a directional speaker but the readings were nonexistent. **Developer response:** In order for this app to work properly, it is necessary to make the microphone access permission settings related to the iOS system. If it is enabled, but it is not working properly, the built-in microphone may be damaged in some way. ### 1/5 — Funktioniert nicht! *2023-03-31* Da eine App Oszilloskop in meinem Haus Frequenzen erkennt bzw gefunden hat, die zwischen 50 Hertz und 100.000 Hertz hin und herspringen und gleichzeitig nebeneinander anwesend sind, war diese App meine Hoffnung, die Ursache dafür zu finden. Ich benutze das neueste iPad. Ich habe BEIDE Apps gekauft "Mosquitone" und HNMF - bei beiden Apps sehe ich keine Bewegung. Meine anderen Messungen belegen das Gegenteil. NUTZT bitte keine solchen Frequenzen, um Katzen, Maulwürfe, Hunde, Mücken etc zu vertreiben! Diese extremen Frequenzen machen euch psychische Probleme, ohne dass ihr darauf kommt, dass sie die Ursache dafür sind. Warum ist das so? Jede Frequenz ist ein Schall / ein Ton und würde zum Beispiel unter einem Mikroskop ganz feine "Bewegungsrillen" in einer Schale mit Wackelpudding zeigen. Unsere Zellen, das Körperwasser kann damit verglichen werden - gerade deshalb sind solche Frequenzen, die wir glauben, nicht zu hören, für unser Wohlbefinden gefährlich. Warum? Weil wir mit dem Gehirn nur etwas ignorieren oder uns daran gewöhnen können (oder übertönen), was wir bewusst wahrnehmen. Warum? Einen Gestank wie von zb Jauche riechst du nach einer gewissen "Konfrontation " nicht mehr so stark (Geruchsadaption). Einen Gestank, den du nicht riechst, wird aber trotzdem von feinen Zellen registriert. Bloß, dass Gerüche keine Schwingung erzeugen. ### 1/5 — No instructions or way to test. *2023-01-05* The app does not have clear instructions to interpret any of the numbers. And it isn’t possible to know if it works before you use it. I believe I should have a refund and plan to request one **Developer response:** Please refer to our support page for this app. You will find reference information on environmental standards for high-frequency noise. ### 1/5 — Doesent work *2020-09-27* Don’t buy **Developer response:** You may be having problems accessing your iPhone's built-in microphone. Please check if you have enabled the microphone input in the iOS settings. ### 1/5 — Zero product support *2020-04-07* I cannot make this app work. The instructions are a single paragraph per option but nothing makes sense. The email address for support is defunct. Highly recommend not paying for this app until they update instructions and support email. **Developer response:** There may be a problem accessing the microphone. Please check if you have enabled the microphone input in the iOS settings. In addition, our support desk email system is working properly.  Please check the email address information on our website again. ### 1/5 — Dose not work at all *2020-03-28* Do not buy. App dose not work at all. Also the email address on the website does not work 😡 **Developer response:** There may be a problem accessing the microphone. Please check if you have enabled the microphone input in the iOS settings. In addition, our support desk email system is working properly. Please check the email address information on our website again. ### 4/5 — シンプルで使いやすい *2021-11-03* 高周波音の探査・測定が目的でしたが、まさに必要な機能でした。測定中のグラフ（？）もとてもわかりやすくてグッドです。 コスパも適当と判断します。 残念な点は、測定できる上限が22kHz程度までで目的としていた測定が半分ほどしかできなかったことです。ハード的な限界だったのかもしれませんが、星一つ減らして星四つとさせていただきました。 ### 5/5 — 素晴らしい。可視化の重要性 *2026-08-05* 長年モス音に悩まされていました。発生源の方向と周波数、デシベルが明確に可視化され、問題解決に一役買ってくれました。アプリで課金したのは初めてでしたが、大満足です。 ## Most praised reviews (8 highest-rated) ### 5/5 — Works well *2026-08-04* It stopped working, I reported it, response was "allow access to microphone". That fixed it. I am used to apps that need access to the microphone asking for it at launch. Lesson learned. **Developer response:** Please check if the app has permission to access the iPhone's built-in microphone for iOS privacy settings. If it is enabled, but it is not working properly, the built-in microphone may be damaged in some way. ### 5/5 — Great little app *2023-12-26* Dog seemed upset. wondered if hf sound. App worked well though dog issue not resolved by this! Easy to use and effective. ### 5/5 — Works very well. *2021-07-15* Had an issue, fast response from dev, it was my phone settings blocking mic access. Helps me track down hf noise from computer and electronic kit. **Developer response:** Please check if the app has permission to access the iPhone's built-in microphone for iOS privacy settings. If it is enabled, but it is not working properly, the built-in microphone may be damaged in some way. ### 5/5 — Geniale App. *2021-07-11* Präzise Anzeige! Hilft, Katzenschreck-Anwender zu überführen. ### 5/5 — Excellent App *2021-04-24* Very good app does what it promises. One can see khz and decibels and one can do a good search and I love the snap feature ### 5/5 — Cyberstalking and torment *2020-01-11* Hi I’m James Beshears and I have been tormented and harassed by a few weman for three years with his or hers app or most app with a pitch up that I can hear but most people can’t. The whistle this or these cell phone are sending out causes all five of the human senses to go crazy pain , muscle ,spasms , nervousness , anger and hysteria. It is being used here in this county as a tool to sexually assault me my wife and several other of the county that know what it is. These weman torment me while I work while sleep I can’t eat without choking and there is a constant ringing if y’all can help me get this stopped I’d hug your neck I’m about to stress out from the harassment 24/7 . The weman doing this to use is locked in jail at the mcminn county justice center in Tennessee Michelle and christy richison or Richardson a a couple of the people doing this I tried tell the law and cos at the justice center they act like I’m crazy because that cand hear the pitch up or freqency they are using. Thank you and God Bless ### 5/5 — Prima ... *2019-02-07* ...- gute App. Ich hoffe, das Mikrofon am iPad ist sensibel genug. ### 5/5 — es funktioniert. *2018-07-26* habe zwei katzenschreckgeräte installiert. mit der app kann überprüft werden ob ultraschall gesendet wird. andere möglichkeiten zum nachweis von ultraschall waren z. t. erheblich teurer als diese app. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
