Apps I designed and shipped — built in SwiftUI, mostly solo. From orthodontic tracking to mahjong analysis to party and card games. All free.
Wear time, trays & smile diary
A companion for clear-aligner and retainer wearers. Track daily wear time toward a 22-hour goal with a live timer and progress ring, watch a color-coded calendar fill in, and keep a timestamped smile diary as your treatment progresses.
Photo recognition · tenpai analysis · discard advice
A Sichuan-mahjong analysis tool. Point your camera at a hand and it recognizes the tiles, tells you whether you're ready to win, lists every winning tile, and ranks your best discard by shanten distance.
Luck and decision
A fast, partnership trick-taking card game for four players. Bid, race to 50 points across six tricks a round, and outplay opponents with a 24-card deck — solo against a strong on-device AI, local over Wi-Fi/Bluetooth, or online in private rooms.
Pass the phone, beat the clock
A party game for people in the same room. Split into a red team and a blue team, spin the wheel to draw a round — describe the word out loud, sketch it, mouth it silently, or act it out — then pass the phone and keep the relay going. Land on Open Buzz and both teams can steal points that round. Fully bilingual in English and Simplified Chinese.
Android build (APK) — enable “Install from unknown sources” to sideload.
Experience the thrill of chance
A digital revolver probability simulator. Set the number of chambers and bullets, pull the trigger, and watch the real-time odds — a playful decision-maker and a hands-on way to feel how probability works.
