About this app
This is a discarding review tool designed specifically for mahjong enthusiasts. During a game, you can record every discarded tile round by round, automatically generating a clear timeline of the discard pile. After the game ends, enter review mode to examine each round's discard choices step by step, marking "missed moves" and writing down the reasons to identify blind spots that led to missed wins or low efficiency. The app supports saving multiple games, statistics on missed moves, and analysis of the most frequently discarded tile types, helping you to understand gameplay patterns from data. It's your personal training partner for improving your mahjong tile reading and discarding judgment.

What you can learn from RiverTurnLog
Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be. The 3 screenshots above are RiverTurnLog's answers to those questions — they're public, they're real, and they made it through Apple's review.
Notice the first screenshot in particular. It's the one users see in search results and on the product page, and it's where most apps spend their best caption and tightest design. Look at the proportion of background to phone, where the text sits, what one thing the image is trying to communicate.
