Crawly

Score RC rock-crawler competitions from your phone. Spectator and Multi-judge sync over local Wi-Fi, no internet or accounts needed. Free and ad-free.

Crawly is a scoring app for RC rock-crawling competitions. Run a comp from your phone, set up courses and classes, register drivers, score runs in real time, and export final standings. No cloud account, no internet required.

HOW IT WORKS One phone hosts the comp. Other phones at the same comp connect over your local Wi-Fi network. Judges score runs on their own phones; drivers see live standings on theirs. Everything syncs over Wi-Fi automatically — no setup beyond joining the same network.

FEATURES • Built-in SORRCA-style scoring with editable penalty buttons • Save your own scoring rule sets as presets • Per-comp custom courses, classes, and time limits • Multi-judge — assign one or more courses to each judge • Live standings on every phone • Penalty and bonus support for any custom rule set • PDF and PNG export of final standings • Offline-tolerant — judges keep scoring even if Wi-Fi briefly drops, then sync when it comes back • Works fine on a single phone too if you're scoring solo

PRIVACY Crawly doesn't collect data, doesn't track you, doesn't show ads, and doesn't talk to any server on the internet. All comp data stays on your phone. All sync traffic stays on your local Wi-Fi. Uninstall the app and every byte is gone.

REQUIREMENTS • Phones running the comp need to be on the same Wi-Fi network. Any home Wi-Fi or phone hotspot works. • The host phone should stay plugged in for long comps
