GesMathPuzze vs Toukasane Lab

GesMathPuzze is a fun puzzle app built around mental math and logical reasoning, featuring two core modes. In Speed Limit, difficulty climbs level by level—from simple addition and subtraction up to three-digit mixed arithmetic. Each question gives you only a few seconds; running out of time or answering wrong ends the game instantly, testing your mental math under real pressure. Longer streaks and higher levels multiply your score. In Number Vault, the code is hidden behind overlapping clues—arithmetic sequences, differences, multiples, parity, and size relations stack together, and you must deduce each digit and crack the lock within a limited number of attempts. The app also includes beautiful animated gradient backgrounds, a personal stats center, a nine-badge achievement system, a daily challenge, and three difficulty tiers, plus built-in how-to-play guides and pro tips. The clean, modern interface is fully adapted for small screens like the iPhone SE and supports iOS 15. Whether you want to sharpen your speed or train your logic, Brain Arena is here to fire up your brain.

Toukasane Lab is an on-device craft assistant for translucent layered washi dyeing. It turns soak, stacking, and wet-press steps into adjustable parameters so you can compare formulas before you work, and review finished pieces afterward. What you can do: • Browse a built-in washi paper library (such as gampi, mitsumata, sugihara, Mino, and handmade thin translucent sheets), inspect absorbency, transmittance, and layer limits, and load defaults into the studio • Adjust moisture level, soak time, layer count, press strength, press duration, and dye strength; see live scores for clarity, evenness, texture, and integrity, plus risk tips • Compare two formulas side by side and get a style-based pick among Fresh / Antique / Deep • Preview multi-layer translucent dye results (Metal compute shading when available, otherwise on-device drawing); zoom, copy a parameter list, and save the simulation image • Choose a finished photo from your library for on-device preprocessing and feature-based analysis of eight dye-related defect types (dry spots, uneven layers, wet-press wrinkles, edge bleed, muddy color, fiber fuzz, layer shift, over-bleed), with cause and fix suggestions • Read a twelve-step process guide, use style samples and parameter templates • Save experiments to a log, archive formulas, search, pin, reuse, and check for duplicate parameter sets What makes it distinctive: • Built around translucent stacking and wet-press craft—not a general color mixer or paint app • Parameters, simulation, diagnosis, and logs stay in one workflow for iteration • No account or social features; craft data stays on your device. Defect review runs locally and does not call an online recognition API • Ambient humidity/temperature tips are in-app references, not sensor readings; photo quality affects diagnosis Made for makers who want measurable notes and fewer blind trials.
