While Anki is powerful, it has a steep learning curve and a dated interface. Booklet provides the same scientific rigor (SM-2 algorithm) in a beautiful, modern app with zero configuration required.
A connection is required for initial sync and to keep your progress updated across devices, but your study sessions are optimized to be fast even on slower networks.
To keep the app accessible to everyone, the free version includes occasional ads. These can be completely removed with a Pro subscription.
Join 10,000+ learners building knowledge that lasts. Free to start. Designed for your long-term mastery.
