### 5/5 — 反応機構

*2022-12-06, version 4.2.4*

このアプリのおかげで有機化学の勉強が捗り、大変お世話になっております。

### 5/5 — とても良い

*2022-03-29, version 4.2.4*

高専で有機化学を勉強しているので助かってます。

見たいものだけをリストに表示できるようにして頂けると助かるのですが可能でしょうか....

### 4/5 — 使いやすいです。

*2022-03-13, version 4.2.4*

大学で有機化学を専攻していた者です。今は有機とは全く異なる内容の仕事をしていますが、時々有機化学が懐かしくなって勉強し直すときにこのアプリが凄く役立っています！

### 5/5 — 学生の味方

*2021-07-25, version 4.1.1*

テスト前に分厚い有機の教科書を上下巻持って勉強する必要がなくなりました！
動画にも飛べるのが便利です

### 5/5 — とてもよい

*2021-07-09, version 4.1.1*

隙間時間の勉強にとてもいいです！似ている反応も同時に乗せてあるので、頭の整理がしやすいです。 これからもっと人名反応が追加されるとさらに嬉しいです。よろしくお願いします。😁
構造式の名前を良く忘れるので、その問題アプリを作って欲しいです！！！

### 4/5 — 院試対策で活用してます

*2021-05-29, version 4.0.2*

通学時にも気軽に反応機構が学べていいアプリです！

使いやすさとしては、ズーム機能が使えたり、お気に入り機能などがあればより勉強が捗るかなと思いました。これから色々な反応がさらに追加されるの楽しみにしてますね😄笑

### 5/5 — 全員ダウンロードすべき

*2021-05-16, version 4.0.1*

最終的には街ゆくJKが、LINEの次くらいにダウンロードするアプリになると思います！

### 5/5 — 良い

*2021-05-15, version 4.0.1*

検索しやすくて便利！

### 5/5 — 参考にさせていただいております

*2021-05-14, version 4.0.1*

勉強の際にYouTubeをいつも拝見しております。このアプリは、反応機構をちょっと忘れてしまった時などに重宝しております。最近リニューアルされたとのことで、これからにも期待です。

### 5/5 — 神アプリ！

*2021-05-14, version 4.0.1*

大学2回生の者です。
反応機構を調べようと思った時に、いちいち検索して探さなきゃいけなかったのがアプリで見れるようになったので、調べる時間が減りました。有機化学に関わる人なら是非ダウンロードしてみてください。(個人の感想です。)
