Markr is a minimal desktop timer for marking timestamps during a live session. Start a session, drop markers with a button or a global hotkey, and review them in order. Everything lives in memory.

It is built for anyone who records a video or runs a live session and wants to flag the moments worth revisiting without rewatching the whole thing. Start Session resets the timer, Mark logs the elapsed time as `mm:ss`, and Stop Session freezes the timer while keeping the markers visible. The global hotkey (Cmd+M on macOS, Ctrl+M on Windows and Linux) works while another app has focus, but only during a running session.
