The apps
One app per craft, so each one speaks its craft’s language and none becomes a junk drawer. They share the same arithmetic, the same habits about rounding, and the same promises: it works offline, there is no account, and you pay once. Where an app is not finished, the card says so.
Fabric & thread
KnitM8
In developmentGauge that actually accounts for rows, not just stitches — so sleeve increases, armhole shaping and yoke depth come out where the pattern meant them to.
Its free calculators are built and proving themselves against the same discipline as QuiltM8’s.
StitchM8
In developmentHow big a chart comes out on any count of fabric, which fabric to choose, and how many skeins to buy.
4 calculators built and checked
The name was checked against five trademark registers before it was printed here.
Kitchen & workshop
SoapM8
In developmentThree well-known soap calculators give three different answers for the same recipe, and none says why. This one shows the convention, the working, and rounds lye the safe way.
Its free calculators are built, with the lye conventions stated rather than assumed.
How the family grows
A craft joins when its maths rests on things that stay true — the geometry of a quilt block, the way an oil turns into soap, the gauge of a knitted swatch. It stays out when the numbers really belong to somebody’s product catalogue and change with the season. That single test is why there is no candle app here: choosing a wick is a safety decision that no formula settles, and we would rather ship nothing than ship the easy half of it.
And one more at the bench — a fourth craft is written and tested, and it appears here the day its name clears the trademark checks. In this family the checks come before the print.
