Beautiful, calming, fun! Love Arpie.

### 3/5 — "fair", but 1 step away from being great

*2016-01-16*

A great, intuitive, entertaining app for building nice sounding ambient music and arpeggios. ******* BUT!   one HUGE element is lacking and if it was added, it would be a shining class-leading app.  And it would be extremely easy to modify:  instead of showing simplistic alternating adjacent notes ambiguously labeled, simply use the white/black key format of a standard piano so the user can actually select notes deliberately and compose with this app.

### 3/5 — 綺麗

*2015-03-08, version 1.0*

とても音がいいと思います。時々無性にやりたくなるアプリ。

### 5/5 — Arpie

*2015-02-24, version 1.0*

Love this app, but the sound has suddenly stopped working. Can anyone help? ( I have tried deleting and reloading). Have also tried loading orbita and no sound on that either. (They also don't appear on my app list in settings). Very puzzled.

### 4/5 — Great!!

*2014-12-27, version 1.0*

有料(っても100円とかね^^;)でも買っても良い位、音色やインターフェースが素晴らしい。

音色の種類や、エフェクトとかかけれたらもっと凄いのになーって思います。
