25The ones only Timerr thought to build.
Timers that actually know their job
Generic timer sites give you a countdown and call it a poker clock. These are built for the specific thing you're timing.
Poker Tournament Timer
Full blind structures, chip counts and payout maths. Built for real tournaments, not a countdown in a costume.
Open timer → EducationDebate Timer
Knows actual debate formats — per-speaker limits, protected time and points of information.
Open timer → FitnessInterval / HIIT Timer
Work and rest rounds, Tabata, EMOM and AMRAP — one configurable engine, spoken cues.
Open timer → FitnessBoxing Round Timer
Rounds, rest and warning bells, with the classic three-minute presets ready to go.
Open timer → FocusPomodoro Timer
25/5 focus cycles you can reshape, with a running session log and gentle end tones.
Open timer → CoreCountdown Timer
Any duration, fills the screen, and shares as a live link anyone can open.
Open timer →Open and it's running
No account, no consent maze, no ten-second load. The timer is the first thing you see and the first thing you can use.
Right to the millisecond
Drift-corrected timing that stays accurate even in a background tab — the part cheap timers quietly get wrong.
Fullscreen, dark, shareable
Fill the room's screen, dim it for the gym or the poker table, and send a running timer by link.
