Count down to
what matters.
A dark, timezone-aware countdown app for macOS. Track the days until your next trip, deadline or big day — and pin the one you care about to your menu bar so the count is always right there at the top of your screen.
Dark, hand-built UI — no web views, no Electron. Unsigned, so first launch: right-click → Open.
Countdowner
A countdown for everything you're waiting for
Trips, launches, birthdays, deadlines — Countdowner keeps the days in view.
Live menu-bar counter
Pin any event and macOS shows the day count right in the menu bar. Click it to switch events, reopen the window, or quit.
Timezone-aware
A midnight-in-Tokyo trip rolls over on Tokyo's calendar, not yours — days are always counted in the event's own zone.
Built-in calendar picker
Set the date with a hand-built calendar, add an optional time, and choose from a searchable list of every timezone.
Lives in the menu bar
Close the window and Countdowner keeps counting up top — quietly running until your big day arrives.
Clean dark UI
Hand-built emerald cards, a mini-calendar badge per event and a big day readout. No web views, no Electron.
Plain-text storage
Events live as JSON in ~/.config/countdowner — easy to back up, edit or sync.
Install in seconds
Two ways to get it — pick whichever you like.
1 Homebrew
The tap also carries our other apps. --no-quarantine
skips the Gatekeeper prompt on first launch.
2 Direct download
Heads up: Countdowner isn't yet signed/notarized, so macOS warns on first launch — approve it once with a right-click → Open. Apple Silicon Macs run it via Rosetta (you'll be prompted to install it the first time if needed).
