Toolbox

Android app of small everyday tools and mini-games, styled after Google's search tools (Material You).

Categories Tiles are listed alphabetically within each category, and titles capitalise each word except small ones like "a" and "and". Games with a computer opponent offer Solo (against the computer) and 2-player modes.

Favourites: any tool or game starred, either from its tile's star on the home screen or the star in its top bar Decision Making: Flip a Coin (embossed 3D coin, streaks and history) · Coin Toss (physics: swipe or shake harder to throw higher) · Roll a Die (d4–d20, up to 6 dice) · Dice Toss (physics: 1–5 rigid-body dice thrown across a walled table) · Spinner (number wheel) · Random Number · Magic 8-Ball · Team Splitter (by number of teams or people per team, share as text) Measurements: Bubble Level · Compass (magnetic, with calibration and interference warnings, mark a bearing) · Sound Meter (dB gauge, min/avg/max, 30 s history, calibration) · Step Counter (counts from midnight, goal ring, distance and calories, 7-day chart) · Tally Counter · Unit Converter (10 categories, UK and US measures) · Calculator (brackets, %, live preview, exact decimals) · Tuner (chromatic, guitar, bass, ukulele, violin) Time: Date Calculator (days between, add/subtract, age) · Timer · Stopwatch · Metronome (tap tempo, accents) Fidget Toys (sound and vibration, with one shared vibration switch): Meditate (guided breathing; a steady vibration while breathing in) · Fidget Spinner · Bubble Wrap · Clicky Switches · Rotary Dial · Purring Cat · Rain Stick · Zip & Ratchet Solo Games: Snake · Block Breaker · Reaction Time · Simon · Memory Game · 2048 · Lights Out (with hints and par) · Stack Tower (tap to drop; overhangs are sliced off, perfect drops regrow the block) Duo Games: Snowman (Hangman with a melting snowman instead of a gallows; solo, or two players where one types the secret word) · Tic-Tac-Toe (Solo against the computer, or 2-player) · Connect Four (Solo against the computer, or 2-player) · Dots and Boxes (3×3 to 5×5; Solo against the computer, or 2-player) · Air Hockey (two players on one screen, multi-touch; or Solo against the computer) · Battleships (pass-and-play with a hand-off screen, or Solo against the computer) The coins and dice share one periwinkle palette (CoinColors in tools/coin/CoinArt.kt). Shake to decide works on the coins, dice, spinner, random number, 8-ball and team splitter. Each has a top-bar toggle, shared across all of them.

Home screen Every tile belongs to one category (Category and Tool in Tools.kt), shown as a heading on the home grid. Favourites appear in their own group at the top as well as in their usual category; they're stored as a comma-separated list of routes under the favourites pref. A row of filter chips under the search field narrows the grid to Favourites or one category; tap the selected chip again to go back to All. Search matches a tile's title, its category and its keywords, so "decibel" finds the sound meter and "north" finds the compass.
