Focus is a resource that runs out, exactly like capital. Thunder Focus is a free Pomodoro timer built for people who work the markets: it alternates deep work sessions with real breaks, tracks your session stats, and helps you step away from the screen when it matters most, which is right after a loss.
The timer works right here, but to install it on your phone or computer and get end-of-session notifications you need to open it full screen.

Set your work and break durations, 55 minutes and 5 by default, then hit Start. When the session ends the timer chimes and switches to the break on its own. In the settings you can pick the break sound, from white noise to rain, turn on daily goals, and schedule time slots that start the timer automatically.
Every completed session lands in your stats, with daily focus charts, a cumulative curve and a breakdown by category. Same principle as a trading journal: what you don't measure, you don't improve.
