Drawpile vs Tayasui Sketches

Drawpile is a drawing, painting, sketching and animation app for people working together on one canvas, with offline use also available. It runs on Windows, macOS, Linux, Android and the web; on iPhone and iPad, the browser version works, but there is no native iOS app. Its toolkit includes more than 200 built-in brushes, several brush engines, a brush editor and stroke stabilization. Layers and layer groups support blend modes, alpha preserve, clipping groups, masking and alpha lock. Animation tools include a timeline and onion skins. Canvases can be saved as OpenRaster or PSD, and images can be pasted from files or other programs. Users can join official community servers without arranging their own infrastructure, or operate a server themselves. External authentication can let users access potentially untrusted third-party servers without sharing their password with those servers. Drawpile says it does not transfer information to other networked systems unless a user or operator specifically requests it. The free plan costs nothing.

Tayasui Sketches is a digital drawing app for Android, iOS, and macOS, designed to make drawing resemble work on paper. Brushes include pencil, acrylic, watercolor, airbrush, ink, and smudge, with many tools responding to Apple Pencil pressure, speed, orientation, and tilt. The app also offers color mixing, gradients, patterns, canvas rotation, guides, and an iPad sidebar. Pro features add unlimited layers, extra tool variations, an extended brush editor, wet watercolor, palettes, and extra rulers. Cloud Sync backs up drawings to iCloud and synchronizes them between devices; the FAQ says this sync cannot be disabled. Pro enables PNG and layered PSD export to other apps. On iPad, two apps can be opened together and layers or documents dragged between them. The free version costs nothing; Pro is a separate one-time purchase with no listed price. Each platform version requires a separate purchase, and drawings cannot sync across versions.
