Compare the workflow, not just the feature list
Check whether the app can open your pattern format, keep a visible place marker, record a row or round, and save notes for the next session. A pattern library without progress tracking will not solve the problem of losing your place.
Using SkeinHub
SkeinHub lets a project hold PDF, image, or text patterns with notes and a saved counter. The pattern workspace is designed so the instructions and progress stay in one project flow. Read the pattern tracking feature for the current supported workflow.
What it does not do
SkeinHub does not automatically understand every pattern instruction or mark completed lines for you. You still decide what you completed and update the counter. That manual step is deliberate: it keeps the record understandable when a pattern needs a personal adjustment.
