Teezee — World Time

See every city's day and night at a glance. Scrub hours or days across real sunrises and sunsets — no time-zone math, ever.

Teezee shows every city you care about as a sky — a timeline painted with that city's real night, dawn, day, and dusk, computed from its actual sunrise and sunset. Line them up, and time-zone math disappears: one glance tells you it's breakfast in London, deep night in Los Angeles, and golden hour in Tokyo.

Drag any timeline and every city scrubs together, so "does 9am Thursday work for Sydney?" is answered by sliding the cursor there and looking.

WHY TEEZEE

• The sky is the interface — each bar sweeps through indigo night, violet dawn, gold sunrise, and blue noon exactly when that city does. You read the world's day at a glance, not in numbers. • Scrub time, not spreadsheets — swipe to slide the shared cursor minutes, hours, or days. Every city follows in lockstep. One tap snaps back to now. • Real sun times — sunrise and sunset for each city's actual location and date, visible right on the bar. • Home offsets — pick a home city and every other row shows its offset from home (−8h, +16h), the number you actually think in. • Menu bar clock (Mac) — every city's time one click away, without opening a window. Optionally show a chosen city's time right in the menu bar. • Keyboard-first (Mac) — arrow keys scrub, ⌘N adds a city, ⌘0 snaps back to now. • iCloud sync — your cities and preferences follow you across iPhone, iPad, Mac, and Vision Pro. • Spatial (Vision Pro) — pin the world's day to your wall in a glass window; look at a timeline and pinch-drag to scrub. • Your labels — rename "London" to "Alice (Eng)" and plan around people, not airports. • 12/24-hour time, seconds display, drag to reorder, light and dark mode.
