A fast, colorful timer for the things you do in chunks — and the things you do until you're done. Intervals, Pomodoro, and open-ended flow sessions. 168 palettes. WHY PULSE Every interval timer looks the same — red background, green active state, none of it yours. And they all only count down, so when the work doesn't fit a fixed box you fight the timer. Pulse counts both directions, brightly, and gets out of your way. Big numbers. Live Activity. Apple Watch. $3.99 once unlocks it all. FLOW MODE (NEW) A flow session counts UP. Focus until you decide to stop; the break you earn is proportional to the focus you put in. • Tap START and go — no countdown, no cap • Tap BREAK for focus ÷ 5 (or ÷ 4, or ÷ 3). 50 minutes of focus earns a 10-minute break • Optional target: a chime when you reach it, then it keeps counting — it never stops you • Optional reminders every 5, 10, 15, 20 or 30 minutes: a soft tick and a haptic • Works locked: the count-up rides your Lock Screen and Dynamic Island, cues still fire 168 PALETTES, SEARCHABLE • Coral — bright red + lime + black (the classic) …and 167 more. Search by color ("orange"), vibe ("neon", "calm"), or era ("70s"). Eight ship free; the one-time unlock opens all 168 and repaints the whole app instantly.
