### 1/5 — Unable to handle larger panoramic images

*2016-09-06*

Could be good if it was able to handle larger 360 x 180 degree panoramic images, but unfortunately it currently just comes up with an error message: "The panorama image can't be loaded".

### 5/5 — Tremendous!

Love the app! Thank you so much for creating this simple viewer. Will come in very handy for anyone shooting in 360 format.

### 5/5 — リコーのThetaにも対応！

*2014-08-02, version 1.0*

リコーのThetaの全天球カメラを試してみたらとても良い！サンプルにあるパラレルがとても興味あるが、クリエイターはどこで買えるのかは不明。写真とCGの2画面は試してみたいかも。

### 5/5 — 使いやすい(^^)

*2014-08-02, version 1.0*

CINEMA４DやMAXでスフィアレンダリングした時に簡単に見れるアプリがないかなと探していました。
ジャイロ機能に対応しているのが他にないので、かなりいいです。
