Equation & Expression Solver vs GenAI Lab

Equation & Expression Solver helps middle and high school students solve and simplify algebra — and actually understand it, by showing every step along the way. Type an equation or expression on the built-in math keypad — variables, fractions, exponents, and parentheses included — then tap Solve or Simplify. You get the answer AND the worked steps that lead to it, the way a teacher would write them on the board. What it does • Solves linear and simple polynomial equations • Gives square-root answers in exact, simplified form — x² = 20 is ±2√5 — with the decimal approximation on the line below, so you get the form to hand in and the number to sanity-check it against • Simplifies expressions, combines like terms, and distributes • Adds, subtracts, multiplies, and divides fractions — even with variables • Factors differences of squares, sums and differences of cubes, and trinomials • Shows the work, step by step, with a clear caption for each move Built for learning • A custom keypad made for math — no fighting the keyboard • Clean, readable notation for fractions, exponents, and roots • Honest answers: when a problem is beyond it, it says so rather than guessing No accounts, no ads, no data collection. Just you and the math.

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?
