TileSight
Point at the hand. Get the score.
TileSight reads a winning mahjong hand from one photo and counts it for you, in Hong Kong or Riichi rules. Everything runs on your iPhone.
Made for the real table
Scan and score
Lay the hand down and take one photo. TileSight finds every tile, splits the hand into sets the way that scores best, and shows the total.
Fix any tile in one tap
Tiles it isn't sure about are marked so you can check them. Tap any tile to change it, and the score updates as you go.
Hong Kong and Riichi
Hong Kong old style with flowers and your own house rules, or Japanese Riichi with han, fu, dora and red fives. Switch rules for a single hand.
Keeps score for the whole game
Four players, seats and rounds, with every payment worked out. Undo a hand, and look back at past games and saved hands.
Share the win
Turn a big hand into a card with the tiles and the score, or share how the night ended: standings, biggest hand and a line about the winner. Rare hands get a gold finish. Send it to the group chat as a picture or an animation.
Want your table's rules?
TileSight is growing, with more rulesets and features on the way. If your table plays a style we don't score yet, or you have an idea for the app, tell us. We read every message.
Nothing leaves your phone
Tile detection runs on your iPhone. There's no account, no ads and no tracking. Your hands and games stay on your device, or in your own iCloud if you turn on backup.
Support
Which rules does TileSight score?
Hong Kong old style (fan, with flowers and editable house rules) and Japanese Riichi (han and fu, dora, red fives and the standard payments).
Can you add the rules my table plays?
Yes, we plan to add more rulesets and features. If you'd like your rules in TileSight, email support@tilesight.com and tell us how your table scores.
Does it need an internet connection?
No. Reading the tiles and scoring both happen on your phone, so it works at any table.
A tile was read wrong. What do I do?
Tap the tile and pick the right one. Tiles the app is unsure about are marked, so check those first.
Is TileSight for gambling?
No. TileSight keeps score in points only. It does not handle or track money.

Privacy policy
Last updated 10 October 2026
TileSight Mahjong is built so your data stays with you. This policy explains what the app uses and why.
What we collect
Nothing. TileSight has no account and sends no personal data, photos or usage data to us or to anyone else.
Camera and photos
The camera, and any photo you choose from your library, is used only to read the tiles. This happens on your iPhone. Images are never uploaded.
Sharing
When you share a card, TileSight hands the picture or animation to the app you pick, such as Messages or WhatsApp. It goes only where you send it, and we never receive a copy.
Data stored on your device
- Saved hands, their photos and your game history are stored on your iPhone.
- If you turn on backup in Settings, this data is also saved to your own private iCloud account through Apple. We cannot see it.
- Settings such as your tile style and house rules are stored on your iPhone.
Tracking, ads and analytics
TileSight shows no ads and contains no third-party analytics or tracking code. Apple may provide us with anonymous, aggregated App Store statistics such as download counts.
Children
TileSight does not collect personal information from anyone, including children.
Changes
If this policy changes, the new version will be posted on this page with a new date.
