Rowtine is a knitting and crochet app. It keeps in one place what is
usually scattered across a project: yarn stash, PDF patterns, row counters
and project notes.

Features:

Track every project from cast-on to finished piece. Between sessions the
app remembers where you left off.
Import a PDF pattern: sections, rows and sizes are rebuilt automatically,
entirely on the device. Patterns in English, French, German and Spanish
are supported.
Read a pattern with a size selector: every number in the text is
filtered down to the chosen size.
Follow a chart row by row, with a movable marker and an abbreviations
sheet always at hand. On a tablet, the chart and the text can be shown
side by side.
Manage a yarn stash: what is reserved for a project, what is still free,
with a warning when there isn't enough left to finish a piece, including
multicoloured yarns (gradient, self-striping, speckled, hand-dyed).
Track the cost of every project; purchases and gifts are recorded
separately.
Look up a needle or hook size from a yarn's ball band and a pattern's
gauge.
Two standalone tools: an increase/decrease distribution calculator and a
free-standing counter.
Metric or imperial units, five currencies.
Interface, in-app guide and pattern import in English, French, German
and Spanish.

The app works offline and keeps all data on the device: no account, no
data collection, no server.
