Mobile App

Valuta is an iPhone currency converter with a calculator keypad built in, so you can convert a price and then split it, add tax, or multiply it without switching apps. It saves recent rates for offline reference, stores favorite currency pairs locally, and has a one-time purchase with no account.

Yore is a local-first iPhone app that replaces half a dozen single-purpose trackers with one library, log, and diary for movies, TV, anime, books, manga, games, music, podcasts, board games, and comics, with metadata pulled from public, no-key sources.

Provato is a local-first iPhone app for tracking restaurants and cafes you tried or want to try, with notes, ratings, photos, locations, history, and wishlist items. It is built for the specific problem of forgetting which coffee shop was worth returning to.

Baby Book Tracker is a simple, local-first iOS app for logging reading sessions with your baby, tracking progress toward goals like 1000 Books Before Kindergarten, and sharing the routine with caregivers. No account is required, and full access is a one-time unlock rather than a subscription.
