Careful tools for people who make things.

An independent software studio in the Netherlands. Bracketworks runs your tournament in the browser today. Woodworking Designs draws your next build, and Nonobonanza draws pictures out of numbers, both heading for phones.

Woodworking Designs

Lay out parts in 3D, hang a door that actually swings, and walk into the timber yard with a list you can trust.

Available on the App Store and Google Play

Build it before you cut it

Add each board and panel, move them until they sit right, and let them snap flush against each other. Resize one and every measurement follows, so the sizes always match the picture.

A wall cabinet in the 3D canvas with every part named on it: door, top, back, bottom and both sides. The selected top reads 56.4 by 40 by 1.8 centimetres.

Hinges that move

Attach a hinge to an edge, set how far it opens, and swing the door. If the door bangs into the cabinet on screen, it will do the same in your workshop.

The same cabinet with its door, tinted teal, standing open on the red hinge line down the left edge of the cabinet.

Cut list and buy list

A list of every part at its finished size, and a shopping list of the boards to buy, in the sizes the shop actually sells, not sizes you have to work out yourself.

The app's cut diagram: two 360 centimetre lengths of 45 by 95 spruce, each drawn as a bar with the parts that come out of it (two long aprons and a leg on the first board, three legs on the second), the percentage used, and whether the offcut is worth keeping.

Open Bracketworks

The knockout stage of a tournament in Bracketworks: two semifinals feeding a final, each box carrying its kick-off time. Delftse Duikers past Leuven Lobsters 9 to 4 at 11:30, Gent Garnalen past Rotterdam Rays 7 to 6 at 11:55, and the final at 11 to 3, every team with its cap colour beside the score.

A whole match day in Bracketworks: Saturday 14 November 2026, fifteen matches from 09:00 to 12:20, two pools running side by side. Each row gives the pool, the group or knockout round, the white team, the score, the black team, and the club refereeing it. The last three rows are the two semifinals and the final. — One Saturday, two pools, fifteen matches. Every one of them has a time, a pool and a team refereeing it, and no club is ever in two places at once.

Group A's table in Bracketworks: Delftse Duikers first on nine points from three wins, 21 goals for and 9 against; Gent Garnalen second on six; Utrecht Otters and Eindhoven Eels level on one point each, split by goal difference. — Type a score and the table works itself out again: played, won, drawn, lost, goals either way, difference, points.

The export panel in Bracketworks: three buttons, for an Excel workbook, for print or save as PDF, and for the Bracketworks file, each with a line underneath saying what it gives you. — An Excel file built right in the page, a version laid out for paper, and the whole tournament as one file you can keep or email.

Four formats: Round robin, single and double elimination, or pools feeding a bracket, each laid out the way that format should look
Scores that carry forward: Enter a result and the next round fills in. Correct one and everything after it is worked out again
Courts, times, referees: No team is ever down for two matches at once, or refereeing while it plays
Paper and spreadsheets: CSV, a proper Excel workbook, and a schedule you can print or save as PDF

Nonobonanza

A nonogram for your phone. Fill in the squares the numbers describe and a picture turns up, and nobody tells you what it is until you have finished it.

Coming soon to iPhone and Android

See what it does

A twenty by twenty board part way through: the top nine rows are filled in and read as the ears and eyes of an animal, and every finished row has crossed off the squares that cannot be filled. — Fill or cross. A row whose numbers add up crosses off its own leftovers, so you never count it twice.

The reveal: a wolf's head in filled squares standing alone on the page with the word Wolf under it, and three ways on: Home, Play again, and Next. — Finish it and the clues clear out, the drawing slides over, and it finally gets its name.

The awards wall before anything has been earned: a locked chest drawn in filled squares with cobwebs in both top corners, under the words The chest is not budging. Fifty pictures and it opens. More awards after that, and more being made. Spiders included at no extra cost. — Every fifty drawings, a hand-made animation and a kind line under it. Neither is printed anywhere but in the app.

500 drawings: From six at five by five up to two hundred and three at twenty, and a daily that runs 344 days before it repeats
Proved solvable: Every one has exactly one solution and can be finished by logic alone. A test says so on both platforms before a build goes out
Nothing to buy past: No ads, no paid coins, no lives and no hint bundles. No account, no network calls, and a manifest that asks for zero permissions
Ink and Paper, both ways: A real light and dark pair, where the dark half is printed on dark stock rather than inverted
