I’m a climber, and I got tired of logging routes in Notes or not logging them at all. Griplog is a private climbing logbook for iOS: track routes and sessions across bouldering, sport, trad, and deep water solo, group them by location, and mark the beta on your photos so you remember the crux next time.

I’d never written a line of Swift before this. It’s the project that taught me iOS development, built with Claude Code alongside me the whole way.

Griplog is heading into private beta soon. More on griplog.app. I’ve also built DuoTimer, a companion app focused on hangboard and finger training.
