### 2/5 — コンセプトは求めていたもの

*2026-01-15, version 1.0.1*

本当に、こんな物が欲しかった。ただ、赤い字すら見える。マジで。赤い字の周りが白っぽくなって余計目立つかも。光ってるみたい。
機能がまともになったら化ける。

### 4/5 — めちゃくちゃ消える‼️

*2025-12-07, version 1.0.1*

出先で赤シートがない！！ってなった時に使っています。
色も細かく変えることができるので、調整すれば緑シートにもなります！
結構使いやすいです！
ただ、本当に画面がずっと色シートのままなので、穴埋め問題に答えたい時などにいちいちスマホを外さないといけないのが少しめんどくさいと感じてしまいます。
画面をタップするとシート状態が外されて、もう一度タップするとシートに戻る、みたいな機能をつけてくださるとありがたいです。
ご検討よろしくお願いします🙇‍♀️

### 3/5 — 惜しい

*2025-11-13, version 1.0.1*

発想はとてもいいのにオレンジ見えちゃいます！青はわからないです！カメラに赤シート貼り付けるほうが見えません！

### 5/5 — シンプル

*2025-09-23, version 1.0.1*

他のごちゃごちゃしたのより断然いい。緑と相性がいい。設定で変えられるから赤シートの上位互換

### 3/5 — うーん、、、

*2025-09-03, version 1.0.1*

完全に文字は消せているわけではないが悪くはない

### 1/5 — これダメ

*2025-08-21, version 1.0.1*

全然見えるので意味ないです。
星1も押したくない。

### 4/5 — コンセプトはめちゃくちゃいい

*2024-12-24, version 1.0.1*

やることはシンプルでめちゃくちゃいいいいです。これを探してました…が、オレンジで書いたペンが消えない！黄色いマーカーも微妙にですがわかってしまいます。
ですがアプリの方向性はめちゃくちゃいいです。シンプルイズベストです。今後のアプデに期待しています。

### 1/5 — 見えるすぎる

*2024-11-26, version 1.0.1*

普通に開いたら全然見えるやんってなって色調節出来るとこあったからこれで行けんじゃね？ってなって調節色々したけど無理でした
普通に市販で売ってる勉強出来る問題集みたいなのでやって無理でしたん

### 1/5 — 意味なしです

*2024-11-07, version 1.0.1*

文字が普通に見えます

### 5/5 — かみ

*2024-10-25, version 1.0.1*
