Field notes
The homepage separates tools into sizing, blankets, pattern math, shaping, yarn and materials, units, and tracking. Its gauge guide points out that four inches is 10.16 cm, a small conversion difference that can compound across a larger project. Yarnivo says project records can be exported as JSON or cleared from local storage; the page does not describe cloud syncing.
