### 4/5 — Recording

*2022-10-21, version 1.11*

I wish my phone wouldn’t turn off when recording.

### 4/5 — Not a fake review - very easy to use

*2022-06-15, version 1.11*

Didn’t ask to sign up just went straight to using it with small catch of watching a short ad every 5 or so videos you record.

Only tiny downside was not being able to download the acapella video as a whole - individual vids only but thats fine w me

### 1/5 — 使い物にならない

*2022-03-10, version 1.10*

音がめちゃくちゃズレる上に編集出来ません。

さらに音が大きいとすぐ割れます。

どう頑張っても使い物になりません。

### 2/5 — ズレます

*2022-02-13, version 1.7*

簡単操作で分かりやすいのが良いですが、ひとりアンサンブルでは音がズレたり音質も悪くて現状では使えません。改善してもらえると嬉しいです。

### 1/5 — Fix more glitches

*2021-01-26*

Every time I try to turn the camera view it glitches me out of the app.

### 3/5 — It’s Okay

*2020-12-12*

It’s okay, but once you use it one time u either have to purchase unlimited or watch an ad every time.  The way it works is pretty cool tho
