verse & observation

One book, two explanations

One book, two ways to read it: the verse as it was revealed, and the world as it is measured. Neither claims to prove the other.

Revelation · 21:33

وَهُوَ ٱلَّذِى خَلَقَ ٱلَّيْلَ وَٱلنَّهَارَ وَٱلشَّمْسَ وَٱلْقَمَرَ ۖ كُلٌّ فِى فَلَكٍ يَسْبَحُونَ

Observation · Orbital mechanics

A body stays in orbit because its speed and the pull of the more massive body balance out. Too slow and it falls inward; at escape velocity it leaves the orbit altogether.

the question behind it

Code outlives its authors

Software written in the nineties still runs today. Its authors are long gone, their names appear nowhere — the code keeps working.

This platform is built on the same question: what of it still runs when no one tends it?

What we are building

01
Precise prayer times
Astronomical offline calculation (MWL, ISNA, Umm Al-Qura and more) after a single location lookup. No connection required afterwards.
02
Qibla compass
Device sensors plus offline calculation — works without network.
03
Quran & Adhkar
Offline Mushaf in multiple languages and fonts, Hisn Al-Muslim, Ruqyah and daily Adhkar.
04
Tracking without surveillance
Khatma goals, digital Tasbeeh and a Ramadan dashboard — your data stays yours.
05
Public API
A free, rate-limited API for prayer times, calendar conversion and Quran data — for other developers to build on.

Our promise

  • No ads — ever.
  • No tracking, no selling of data, no third-party analytics.
  • No paywalls, no premium tier, no subscriptions.
  • Fully open source, auditable by anyone.

My Athar

I build this platform so that it remains: free, without ads, without tracking.

And as long as someone uses it to pray, the reward continues.

My athar is to inspire. Yours might be a line of code, or a tree, or a mark on the heart of a child who saw how you lived.

Find your Athar.

Roadmap

  1. 01

    Web tools

    Prayer times (live, location-aware), Qibla compass and Hijri calendar — running in your browser now.

    Live
  2. 02

    Calculation core

    A single shared library for prayer times, Qibla and Hijri conversion, used by web, API and mobile alike. The web currently computes these itself in JavaScript — this phase replaces that with one portable engine.

    In progress
  3. 03

    Public API

    Free and rate-limited, documented for third-party developers.

    Next
  4. 04

    Mobile apps

    Android and iOS — offline-first, reliable Adhan notifications, widgets and Live Activities.

    Planned
  5. 05

    AI Quran explanation

    AI that explains the Quran from science and connects it with text, video and images that never existed before.
