NURA · The app

Ramadan and fasting, counted from your own real prayer times

Most fasting apps hand you a generic timetable pulled from a server. NURA does something more honest: the suhoor and iftar countdown is derived from your Fajr and Maghrib for your exact coordinates, computed on the device by the same deterministic solar-astronomy engine that powers the rest of the app. The fast begins at Fajr and opens at Maghrib — that is the whole rule, and NURA follows it to the minute.

The live fast window

NURA reads today's Fajr and Maghrib instants straight from the prayer engine's schedule and works out which of four states you are in, ticking once a second so the countdown is truly live:

• Suhoor — before dawn. The pre-fast window is still open; the counter targets Fajr and is labelled simply “Suhoor ends.”
• Fasting — between Fajr and Maghrib. The counter targets iftar, with a progress bar showing how much of the daylight fast has elapsed.
• Complete — at or after Maghrib. The day's fast is done, marked with a quiet check.
• Unknown — on a polar day where the sun never crosses the relevant angle, NURA says so plainly rather than inventing a time.

Every label is a plain noun — “Suhoor ends,” “Iftar,” “Fast complete” — never a pressuring “hurry.” When the engine omits Maghrib, NURA falls back to true astronomical sunset, which is the same event, computed by the same math.

A one-tap fast log, with the Sunnah built in

Mark today fasted with a single tap and it is kept on the device. NURA knows which days the Sunnah singles out and tells you when today is one of them:

• Mondays and Thursdays — the days the Prophet ﷺ fasted (Tirmidhi).
• The three white days — the 13th, 14th and 15th of each Hijri month (Bukhari & Muslim), detected from the real Islamic calendar rather than a hand-rolled table.

From that, NURA counts your streak of consecutive recommended fast days kept — scanning back day by day, ignoring ordinary days, and stopping cleanly at the first recommended day you missed. Today, if it is a recommended day you have not yet marked, is treated as still pending: it neither counts nor breaks the streak.

Countdown to Ramadan and Eid

The days to the coming 1 Ramadan and to Eid al-Fitr (1 Shawwal) are read from the platform's Umm al-Qura calendar the same way NURA's Hijri date is — never from a static lookup table that quietly ages. When Ramadan is already here, the tool shows the day number instead and counts down to the Eid that closes this very Ramadan.

Why the math is trustworthy

Every calculation in this tool is deterministic given its time argument. There is no randomness, no network call, and no server round-trip — which is exactly why it can be pinned by an automated test suite and why it behaves identically offline, in airplane mode, or on a plane over the ocean. NURA's whole engine layer is built this way, and the Ramadan module is covered by the app's roughly 1,327 automated tests and by an independent 14-agent adversarial bug audit.

Private by architecture

Your fast log and settings live on your device, not on our servers — we don't run any for the core app. The optional AI assistant, Noora, is bring-your-own-key and only ever engaged when you choose to enable it. Nothing about your fasting leaves the phone on its own.

NURA is a free, watch-first Muslim life-companion for iPhone from NuroNova Genix Co. (Delaware; headquartered in Houston, Texas). Prayer times, Qibla, the full athan and every daily tool work offline, with no sign-in. Coming soon to iPhone.
