NURA · The app

A world clock that keeps Makkah on your wrist

Families and communities are spread across the globe, and so is the ummah. NURA's world clock keeps the cities that matter to you on one glanceable list — with Makkah there from the first run — and shows the live wall-clock time in each, whether that city is a calendar day ahead of or behind you, and whether the sun is up there right now.

Correct timezones, never typed by hand

Every city comes from a curated pool with its correct IANA timezone identifier, so you can never accidentally create a place with a wrong or invented zone. The pool spans the Muslim world and the major diaspora hubs:

• Makkah and Madinah (both legitimately on Asia/Riyadh, kept as distinct places on purpose)
• Cairo, Istanbul, Dubai, Karachi, Delhi, Dhaka, Jakarta, Kuala Lumpur, Lagos
• London, Paris, New York, Toronto, Los Angeles, São Paulo, Tokyo, Sydney

On first run NURA seeds a sensible starter list — Makkah, your own city, London and New York — de-duplicated by timezone so a London-based user never sees London twice. Add or remove cities freely; your chosen list is kept on the device.

Reads that respect the date line

The time in each zone is read with the platform's own Intl.DateTimeFormat, using a 24-hour internal cycle so midnight is 0 and never 24, then displayed in whichever 12- or 24-hour format you've set for the rest of the app. Two small signals make a busy list instantly legible:

That day/night dot is honest about its own limits: it is only there to colour the list, never for anything devotional. Prayer times always come from NURA's real, deterministic astronomy engine, not from this rough marker.

Quiet, tested, and offline

The list refreshes gently — the display only shows minutes, so a light tick every few seconds keeps it honest without a busy loop draining the battery. All the timezone arithmetic lives in a pure module the component only draws, which is why it is covered directly by NURA's automated test suite (~1,327 tests) and works with no signal at all. A bad or unreadable entry degrades quietly to a dash rather than breaking the screen.

There is no account and no NuroNova server: your chosen cities are stored on the device and never leave it.

Part of the everyday toolkit

The world clock sits alongside NURA's other Now-tab tools — the Hijri date, the sunrise/sunset arc, the tasbih, the water counter, the stopwatch and timer, and the zakat calculator — a full set of daily instruments built to the same standard as the prayer engine that anchors the app.
