Splatr screenshot

The tool that should exist.

macOS doesn't ship with a basic paint program. If you want to draw a quick diagram, edit a screenshot, or put a red circle around something — your options are an Electron app, a subscription, or overkill.

Splatr is the paint program I wanted. Swift, SwiftUI, and a custom bitmap engine. Opens instantly. Does exactly what you'd expect.

16 Tools

Everything a paint program needs. Nothing it doesn't.
