A small toolbox
Six tools, built because I needed them. They work without a connection once the app is installed, and none of them sends anything anywhere.
The tools
The bench
Small exact tools: spelling on the phone, and more to come. Each gives a value and cites the standard it comes from.
5 calendarsThe calendars
Environment, health, cross-border tax, phrases, and a joke a day. One door at a time.
DailyA door a day
One door per day of the year: a word, a rule, a false friend. Everyone opens the same door - explained in your language.
PracticeWorkplace German
Office German, not textbook German. Leitner boxes: get it wrong and the word comes straight back.
CheckContrast checker
Two colours, one verdict - and the nearest fix that keeps your hue.
Cross-borderThe Cliff
Live a year of cross-border telework and watch two thresholds count you. One counts days, the other a share of time, and neither warns you. A Luxembourg payslip is decoded line by line.
The games
Same rules as the tools: everything runs offline, nothing is sent anywhere. They are here because a game is the shortest way to show that a rule has been thought through to the end - and because they were a pleasure to build.
Aya's Warehouse
A crate-pushing puzzle that tells you the moment a crate can no longer be saved. Eight levels, three languages, and a level editor that refuses to save the unsolvable.
AsideThe Firefly Round
A gentle garden game. Wake the sleeping fireflies and lead them home to the lantern. Nothing to defeat, nothing to lose.
Learn & playThe Last Stroke
The paper game of boxes, with questions inside. Close a box, then earn it: German, French, English, compliance, digital security. Hard questions weigh more, and points win - not boxes.
StrategyFour Seeds
Twelve pits, forty-eight seeds, nothing hidden. Sow, harvest, and read three moves ahead - against a computer that reads seven. A West African sowing game, Abapa tournament rules.
ReflexThe Shuttle
The cloth comes down and never stops. Every thread the shuttle frees pushes it back up and lengthens your band. Four threads of one colour in a row set that colour loose. Your band is your score.
Night driveThe Co-Driver
Your headlights reach a hundred metres. The corner is three hundred away. Your co-driver reads the book and calls what you cannot see. Every fork offers a shortcut he has never driven, and on it he goes quiet.
DuelThe Ember
The puck heats up. Every return without a goal moves it one step - cold it is worth one point, blazing five, and a goal conceded costs exactly the same. Pull your mallet back to cool it. Four opponents, four habits to take apart.
