FlashDB vs GenAI Lab

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.

GenAI Lab is an offline, hands-on course for understanding and prototyping generative AI systems, one experiment at a time. Learn how modern AI actually works by exploring it visually and interactively, right on your iPhone. No internet, no account, no tracking. A GUIDED CURRICULUM The course spans 8 tracks and 52 short missions covering: - GenAI foundations - Transformers and LLMs - Prompt engineering - Retrieval-augmented generation (RAG) - Image generation - Fine-tuning - Evaluation and safety - Multimodal AI and agents Every mission combines a concept check, a matching activity, and a guided Python code fragment so you learn by doing, not just reading. TRANSFORMER ARCADE Six short visual games and six boss challenges bring the internals of transformers to life: - Tokenization - Embeddings - Attention - Multi-head attention - Transformer blocks - Next-token generation Arcade rounds are untimed, offline, replayable, and use deterministic simulations so you can inspect exactly what is happening. LEARN BY EXPERIMENT The built-in simulators use deliberately small, deterministic examples so you can inspect attention weights, prompts, retrieval, diffusion controls, and agent loops step by step. Code activities validate guided fragments to build your intuition; the app does not execute arbitrary code. PRIVATE BY DESIGN Your progress is stored only on your device. GenAI Lab has no account, no ads, no analytics SDK, and makes no network requests. Learn anywhere, even completely offline. WHO IT IS FOR - Students and self-learners exploring how generative AI works - Engineers who want a clear mental model of transformers, LLMs, RAG, and agents - Anyone curious about the ideas behind modern AI, in a focused, no-pressure environment Questions or feedback?
