### 5/5 — Small learning curve but easy to use

*2026-06-15*

Once you switch the language (basically common sense skill level to do) it’s pretty easy to use, no clue what that other review is yapping about. Def recommend for anyone who wants to get better at Othello/Reversi

### 2/5 — ????

*2024-12-13*

i’m not saying it doesnt work . i’m not saying it’s bad.  i’m saying i have no idea how to use this and can find no instructions

### 2/5 — 使いづらい

*2021-06-24*

下の評価値のグラフに触れても反応しないことが多い。
もう少し点を大きくして反応しやすくして欲しい

### 1/5 — 見辛い

*2021-01-07*

序盤は評価値プラスとマイナスで色分けしているのに、終盤は青一色の意味がわからない。

### 1/5 — カメラで取り込んだ

*2020-10-30*

カメラで取り込んだ盤面の評価がされるようにして欲しい

### 4/5 — 評価値が出ない時があります

*2020-09-10*

全ての評価値を表示に設定していても、評価値が出ないのはなぜでしょうか。

もし解決方法が有れば教えて頂ければ嬉しいです。

### 4/5 — 素晴らしい

*2019-08-05*

オセロクエストから棋譜をコピーして解析できるのがすごく便利。
…ただ他の方も言っているように、過去に撮影した写真から盤面を再現できる機能と、自由に盤面を作成できる機能は欲しい。
あと、一度、盤面の「打てない箇所」をタップして一手戻さないと全ての評価値が表示されないのは何故？

### 2/5 — 改善お願いします。

*2017-11-04*

フリーズしたりアプリが落ちたりします。

### 1/5 — これはひどい

*2017-04-16*

10〜15手目位には計算が追い付いてないです。
お金払ってでも買う価値はないと思われますので買うのは控えたほうがいいかと

### 5/5 — 買って損は無い

*2017-04-09*

360円でこれは最高っす。おかげでオセロ強くなっている気がする。
