Mobilní aplikace pro učení prostřednictvím flash-karet

Abstract

This bachelor’s thesis presents the design and development of the iOS application SpacedCards, which supports effective learning through digital flashcards and spaced repetition. The key innova- tion is the „study to scroll“ mechanism that uses the ScreenTime API to temporarily limit selected distracting apps and grants a configurable amount of scrolltime minutes for each reviewed card. Users unlock entertainment time gradually, card by card, rather than after meeting a daily goal. The thesis surveys current approaches to mobile app development with an emphasis on cross- platform solutions and details an implementation in Flutter. It integrates the FSRS (Free Spaced Repetition Scheduler) algorithm to optimize review intervals, Gemini API for AI-assisted card con- tent generation, and an offline-first architecture with automatic synchronization via PowerSync. Native iOS integration is implemented through Platform Channels. The solution also employs Riverpod (state management), PostHog (analytics), Sentry (error tracking) and Superwall (mone- tization). The application was originally tested and published on the App Store under the name SpacedCards; the current production version is available as Study G. The resulting solution combines proven didactic principles with modern technologies and a „time-for-performance“ gamification logic, motivating regular study and the formation of consistent learning habits. Finally, the thesis outlines directions for future development and discusses the chosen monetization model.
