Focast is a minimal natural sound focus timer for macOS. Focast works entirely offline, requires no account, and is built natively for the Mac. You can mix real recorded nature sounds, start a timer, and let your focus accumulate over days through a calm visual history. Focast is designed to feel less like a tool you constantly interact with, and more like a space you enter. For people who write, study, code, read, or think, sometimes the most useful software is the one that does the least.
