FlashDB is a simple, focused flashcard study app. It does one thing well: lets you study cards you create or import, without ads, accounts, trackers, or cloud services. STUDY YOUR WAY • Quiz mode shows four answer choices for every question. • Flashcard mode flips cards to reveal the answer. • Pick the number of questions per session — 5, 10, 20, 50, All, or any custom count. • Shuffle questions so you don't memorize the order. BUILD YOUR DECK • Add questions one at a time from inside the app. • Import question sets from a JSON file in your Files app. • Attach images to questions for visual prompts. • Export the whole database to back it up or share it. ORGANIZE WITH TAGS • Tag any question with one or more labels. • Use the Filter by Tag button on the home screen to scope a session to just the tags you pick. • Tags travel with exported JSON. TRACK YOUR PROGRESS (OPTIONAL) • Show Live Score and an answer-confirmation haptic during quizzes. • Track Question Performance counts attempts and misses, then surfaces a Study Weak Only mode for the questions you keep getting wrong. • Show Study History gives you a daily streak and a 7-day session count on the home screen. • Every progress feature is off by default. Turn on only what you want. DESIGNED FOR EVERYONE • Full VoiceOver support, including custom rotor actions for flipping and moving between cards. • Honors Reduce Motion, Dynamic Type, and your color scheme. • iPad keyboard shortcuts: Space to flip, ← and → to navigate cards, ⌘N to add, ⌘S to save. • Optional "blind quiz" mode hides per-answer feedback so you only see your total when the session ends. PRIVACY YOU CAN VERIFY • No accounts, no sign-up, no tracking. • No third-party analytics or ad SDKs. • No internet access required after install. • All questions, images, and session history stay on your device. A small starter set of 25 sample Spanish-English questions is bundled with the app so you can start studying the moment you open it. Add your own, import sets you've found, or delete the starter cards and never look back — it's your library. FlashDB is intentionally simple. Every visible new feature is gated behind a setting that defaults to off, so the app stays focused unless you decide otherwise.
