### 1/5 — No sound at all.

*2026-02-03*

Doesn’t work. Bogus. Do NOT download.

### 2/5 — Buggy, can’t seem to change frequency

*2023-06-01*

Can’t seem to change the frequency in direct mode.  Ads are also annoying since this app doesn’t really work well.

### 1/5 — Stopped work after first day

*2021-09-27*

Worked great when first downloaded. Tried on second day. No sound.

### 1/5 — No sound

*2021-06-23*

Can’t get any sound out of the app and on the last tab when you tap “sound on” it just loads forever.

### 3/5 — Loved app before updates

*2020-09-22*

This app has been very useful for me and I used it regularly. However since the recent updates in the last few weeks in the third tab function, the volume and frequency functions have switched, and the on button doesn’t switch to off. The other thing that would be helpful is a how to use section.

### 5/5 — 単音、和音生成など

*2019-10-24, version 1.3*

OSアップデート13.1.3に対応して下さい。

directでは任意の周波数、例えば741Hzなどを生成できます。複数セットして和音も鳴らせます。ヒーリング音源に良いかも。
touchでは、R2D2の声の様なものであそべます。左下角周辺でたっぷ又はワイプします。
ライブとかでもつかえそうです。
DTMFは俗に言うプッシュ音です。

凄く役立つかは別にして、
周波数を指定できて無料なのです。
何の問題がありましょう。
利用法は無限大とも言えます。

広告も控えめでありがたい。

### 3/5 — 何なんだろうこれ…

*2016-10-12, version 1.3*

正直このアプリの使い道全く分からないですw
波形が見れると少し面白くなるかも知れないって思いました。
デザインは一貫してなかなかかっこいいし、悪いアプリではないと思う。

でも何に使うのか…ww
