Time blindness isn't about trying harder.
It's about seeing the clock.

Time blindness is, at its core, a problem of missing internal signals: the brain isn't reliably reporting how much time has passed, so duration has to come from somewhere outside you. That's what "externalizing time" means — making the passage of time a physical object in the environment rather than something you have to estimate. The catch is that not every external clock works. A tray icon, a phone alarm, or a browser-tab Pomodoro all share the same fatal dependency: they require you to remember to check. In a time-blind or hyperfocused state, that's precisely the step that fails. The reminder fires once, you dismiss it, and the cue is gone. A persistent, always-on-top countdown removes the remembering. It sits in your peripheral vision over the work itself, so you pick up "twelve minutes left" the same way you'd notice movement at the edge of your sight — passively, without a deliberate decision to look. The cue is continuous rather than a single event, which is why a visible HUD changes behavior where a notification doesn't. TimeFence is built around that single idea: keep the count where your eyes already are, all the time, and let optional Strict Mode add a harder commitment for the blocks you choose. It stays local-first with no account and zero telemetry, so it externalizes time without becoming one more thing demanding your attention.
