Oshi Check
Find your shared YouTube faves
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Oshi Check is a face-to-face "fave match" app.
When you meet a friend, find out how many of your favorite YouTube channels you have in common — right on the spot. Both of you just tap one button. Your phones connect directly to reveal your shared channels, shared genres, and a fun "overlap score," shown to both of you at the same time. Celebrate with the confetti-filled results screen.
■ Privacy first
Only the channels you BOTH follow are shown to each other. Channels that don't match, and the contents of your subscription list, are never revealed to the other person or to us — protected by a cryptographic technique called Private Set Intersection (PSI). Matching happens through a direct device-to-device connection, never through a server. You choose which channels are allowed to be shared. Keep the private ones off.
■ Three simple steps
1. Import your channels from YouTube and pick which ones you're happy to share
2. Tap "Connect" with the person in front of you (group mode for 3+ also available)
3. See your shared faves and compatibility score — together, at the same time!
■ Great for
- Breaking the ice with someone new
- Finding people with the same taste at meetups and events
- Confirming "wait, you follow them too?!" with friends
■ Oshi Check Pro
The free version allows one match per day. Want more? Watch a rewarded ad to get another, or upgrade to Pro (one-time purchase) for unlimited matches and no ads.
This app uses YouTube API Services. Use is subject to the YouTube Terms of Service and the Google Privacy Policy.

■ プライバシー第一の設計
一致した推しだけがお互いに表示されます。一致しなかった推しや、あなたの登録チャンネルの中身は、暗号技術（PSI）によって相手にも運営にも知られません。照合はその場の端末どうしの直接通信で行われ、サーバーを通しません。「見せてもいい推し」はあなた自身が選べます。秘密にしたい推しはオフのままでOK。
■ 使い方は3ステップ
1. YouTubeから推しを取り込み、共有していいチャンネルを選ぶ
2. 目の前の相手と「相手とつなぐ」（3人以上の「みんなでつなぐ」も）
3. 2人同時に、共通の推しと相性度を発表！
■ こんなときに
・初対面の人とのアイスブレイクに
・オフ会やイベントで趣味の合う人を見つけたいとき
・友達と「実は同じの推してた！」を確かめたいとき
■ 推しくらべ Pro
無料では1日1回まで。もっと使いたい方は、広告を見て回数を回復するか、Pro（買い切り）で回数無制限・広告なしにできます。

Fixed a bug where matches weren't counted correctly. If no ad is available, we now give you one free match back each day.
