## What is JongBook?

The paper score sheet from the mahjong parlor, now on your phone.
Just enter the scores and JongBook calculates everyone's net results for you. No more pen, paper, or calculator for your Riichi mahjong nights.


[Enter scores, get results automatically]
- Enter each hanchan's score and net results are calculated automatically
- Chip and table fee rules are all included, so you know the net results the moment you finish
- Supports both 3-player (sanma) and 4-player mahjong
- Looks just like a paper score sheet, so it's easy to pick up


[Manage your regular players in groups]
- Add the people you play with to a group and create a score sheet with one tap
- Pick "same players as last time" and start right away
- Rules are saved per group, so you don't have to enter them every time

[Share score sheets with friends]
- Invite friends to a group with a link and share its score sheets
- Everyone sees the same stats on their own phone, anytime
- Export results as an image and send them through any messaging app

[Stats tallied automatically]
- Group stats are ranked automatically, so you can see who's winning at a glance
- My Stats brings together your results across all groups: totals, trend, placement, and how you do against each opponent
- Switch between net and score, and filter by period or 3-player / 4-player
- JongBook Pro unlocks even deeper analysis
