### 4/5 — Works flawlessly! But…

*2026-08-25*

…and the full paid version just needs one little tweak by the developers: if you could add one or two steps of higher resolution (32768, 65536) to get the lowest frequencies more accurate measured and displayed. Then this App could be used also to identify and locate standing waves pressure maxima more precise (higher latency due the higher sampling is not too relevant in this specific use-case).
Thank you for your work!

### 4/5 — Frequency picking from spectra

*2026-08-18*

Please add the ability to click on a point in the spectrum to see the frequency

**Developer response:** Thank you for your comment.
In the latest version, we have added a feature that allows users to tap on the spectrum to display the frequency at that location. 
Please check it out.

### 1/5 — Not reading frequency

*2026-06-12*

This does not read frequency like ai said and the app

**Developer response:** Thank you for your comment.
This app shows a frequency spectrum and also detects pitch (fundamental frequency).
If it felt like no frequencies were shown, what kind of sound were you testing with?

### 1/5 — Lost functionality

*2026-05-07*

Spectral analysis no longer available. App has worse interface and less information.

**Developer response:** Thank you for your comment.
This app is designed to be easy to use.
Please explain the specific points that concern you.

### 1/5 — Compromised?

*2026-02-25*

Used it a few times - great. Yesterday, after opening it, a “tool bar” along the bottom appeared with thumbnails showing “porn shots”!
This AM, after opening the App, another “tool bar” appeared at the bottom again, but this time it showed thumbnails of pipes etc. I deleted the App!

No averaging 
No peak hold
I’m a noise expert and this is not useful at all to me

### 1/5 — Security Concerns

*2025-04-04*

The app asks for a credit card number with no info about what if any charges you will be exposed to.  Fail!

**Developer response:** Thanks for your comment.
You didn't write it correctly, did you? This is misleading.
What did you do?

### 5/5 — The best!

*2026-06-19*

The best !!

### 5/5 — Cool

*2026-06-16*

I don’t know about the other reviews from other people, but I think this is fine

### 5/5 — 耳鳴り

*2026-06-12*

耳鳴りの音に同期できる電子音を探していました。専門家ではないので何を触ったらどうなるとかはわからないけど色々触ってみています。同じ周波数なのに左耳と右耳では聞こえ方が違うということを発見しました。個人的には興味深いアプリだと思います。
バックグラウンドで聴けるようになると尚嬉しいです。

### 5/5 — เสปรคตั้ม

*2026-04-25, version 2.2.2*

ดีมากก

### 5/5 — App non funzionante

*2026-04-22, version 2.2.2*

Collegando il cellulare all’amplificatore viene disattivato il microfono e quindi l’analisi di spettro non può avvenire.
È obbligatorio collegare il cellulare all’amplificatore che comanda il diffusore da controllare, per alimentare il diffusore acustico con il vostro emettitore di frequenze.
Ho aggiornato l’app alla versione 2.2.2 ho testato il nuovo selettore che avete aggiunto ma purtroppo non funziona, sia dettato alto che basso, appena si innesta il cavo usb-c il microfono del iPhone si scollega, lo si vede chiaramente dalla vostra analisi di spettro che diventa insensibile a qualunque suono o rumore.
Problema risolto, era la configurazione del microfono iPhone a disabilitarlo all’inserimento del cavo usb-c.
Adesso la vostra app funziona.

### 5/5 — ใช้ใด้

*2026-03-27, version 2.2.0*

ดีครับ

### 5/5 — Free

*2026-03-26, version 2.1.1*

Free

### 5/5 — Pretty good but needs one feature

*2026-03-21*

Everything works as intended with a lot of customization but what would be really nice is a way to change the sampling rate to make measurements more readable.

### 5/5 — Empfehlend

*2026-03-11*

Dieses app übernimmt alle basics. Wellenform, Oscillator, Diese säulendinger, viele coole einstellungen. Empfehlend für einen Spectrum analyzator.
