Flash Study Cards is a no-frills way to build your own decks and actually use them. Create a deck, add cards with a front and back, group them into folders if you're studying several subjects at once. When you're ready, start a study session and flip through cards one at a time, marking each one as known or needs review. The app keeps track of which cards you find difficult and surfaces them more often in later sessions, so you spend your time where it matters. A session summary shows how many cards you reviewed, how many were correct and how long the session lasted. The stats page keeps a running history, week by week, so you can see how consistently you're studying without any pressure to maintain streaks. Decks can be reordered, duplicated and archived. Cards can be shuffled before each session, sorted by difficulty, or filtered to show only the ones you haven't mastered yet. Long-press a card in the list to quickly edit or delete it without leaving the deck view. Import templates come with the app to get started — vocabulary, capitals, formulas — and every template is fully editable. Settings are minimal: dark theme, font size, view mode, haptic feedback and default sort. Everything is stored locally on the device. No cloud sync, no account, no advertising, no internet connection needed. Once you install it, it just works.
