Paint a beautiful piece of art or just doodle on a photo. Only your imagination sets the limits for what you can create! • INSPIRING PAINTING TOOLS • Be as creative as you want with inspiring out-of-this-world painting tools like 3D-Shaded Brush, Halo Brush, Plasma Chain Brush, and Translucent Brush. It also has Lighten and Darken tools, a tremendous help when you want to add some depth and life to your drawings. • FINGERTIP = STROKE SIZE • When you paint, the app measures how much of your finger is touching the screen and changes the stroke size accordingly. Apply just the corner of your fingertip for a thin line, or the whole fingerprint area for a broad stroke. A 2nd tool assigned to your finger will still use this feature, so don’t ignore it just because you have an Apple Pencil! • LEFT-HANDED? • Just swipe the toolbar over to the other side! • PARAMETERS CAN BE CHANGED LIVE • Use any buttons or controls to change/adjust color, size, force, simultaneously while painting. • UNIVERSAL PURCHASE • If you choose to buy the Pro upgrade, this one-time in-app purchase will unlock all Pro features in the app on all available platforms (iPad-iPhone-Mac)! • METAL • The engine is based on Metal, with 128-bit color and floating-point arithmetic. • SWIFT • The app was developed entirely using Swift (earlier versions used C++). • APPLE PENCIL SUPPORT • FULL SCREEN PAINTING • • DARK MODE • LANDSCAPE • PORTRAIT • WIDE COLOR • • MULTIPLE LAYERS • PHOTO TRACING MODE (Pro feature) •

Verdict

The call

The clearest difference is ads: Cosmic Brush at none against Sketch Pro's shown. Sketch Pro's advantage is ratings volume (11K vs 132) and update cadence (every 3 weeks vs every 2 months). On price, rating, review sentiment and in-app purchases there is nothing between them.
