What is Umbra?

Umbra is a native Windows focus app that blocks distracting apps and websites while you work — a free alternative to paid tools like Cold Turkey Blocker or Freedom.

Features: • Pomodoro, free-timer and recurring-schedule focus sessions • Application and website blocking, with reusable blocklist profiles and an optional Hard mode that can't be bypassed until the session ends • A Chrome/Edge/Vivaldi/Brave extension for website blocking, talking to the app over a local bridge (no cloud, no browsing history sent anywhere) • Thirteen-plus built-in ambient soundscapes, mixable up to three at once • Spotify/Windows media info shown during sessions • A draggable, always-on-top floating timer with custom image or video backgrounds • Detailed statistics: streaks, daily/weekly/monthly totals, activity heatmap, blocked-attempt counts • Light/dark themes with customizable backgrounds • No account, no telemetry, no ads — all data stays local in %APPDATA%

Built with WPF/.NET, self-contained installer, in-app auto-update with SHA-256 verification.
