見終わったあとの「あのシーン、何話だっけ」を、ちゃんと残しておくための記録アプリです。 韓国ドラマ、海外ドラマ、映画、アニメ——見たものなら何でも1冊として並びます。 ■ 見た作品が、本棚に積まれていく 記録した作品は、見た年ごとの棚に背表紙として並びます。背表紙の下には蔵書番号のラベル。何度も見返した作品は、背表紙が少しずつ厚くなります。 ■ 何話の何分が良かったかを残せる 「7話 12:34 雨のバス停」のように、話数とタイムコードを添えて書き込めます。1つの作品に何度でも書き足せるので、見ながら気になったところをそのまま置いていけます。映画のように話数がないものは、時間だけ残せます。 ■ 見終わると、チケットの半券が残る 完走するとミシン目で半券がもぎれて、蔵書番号がひとつ繰り上がります。10冊、25冊、50冊……の節目は金色の半券になります。 ■ 種類ごとの書架から探せる 韓ドラ、海外ドラマ、映画、アニメ。棚を開くと、その種類の作品が並びます。見たい・視聴中・完走でも絞り込めます。 ■ 通信しません アカウント登録なし。広告なし。通信なし。書いた記録は、すべてあなたの端末の中だけに保存されます。 表紙は写真ライブラリから自分で選んで、好きな位置と大きさで切り抜けます。

Verdict
The clearest difference is in-app purchases: YOIN at none against OshaberiAI's 1. OshaberiAI's advantage is device support (3 vs 1) and iOS requirement (11.0 vs 17.0). On price and ads there is nothing between them.
