The Origin Story

Chogadia Hisab brings Islamic astronomical timing calculations to mobile devices, based on knowledge from the Ikhwan-us-Safaa kitaab studied at Aljamea tus Saifiyah. The app calculates 12 hours of day (sunrise to sunset) and 12 hours of night (sunset to sunrise), with each hour influenced by different planetary forces.

First Project Philosophy

"Make it simple to use, but comprehensive in functionality. Real-time feedback is essential for an educational tool."

The Challenge

Bringing Islamic astronomical timing calculations to mobile devices required precise sunrise/sunset calculations and an understanding of planetary hour systems from classical Islamic astronomy.

Critical Pain Points

Astronomical calculations must be precise for any location and date
Planetary hours divide day and night into 12 unequal periods each
Users need to check timings for any city, not just their current location
Widget support required for quick access to current planetary hour
Support needed for date range from 1900 to 2100

The knowledge from Ikhwan-us-Safaa kitaab studied at Aljamea tus Saifiyah needed to be translated into accurate algorithmic calculations that work anywhere in the world.

The Solution

Built a comprehensive planetary timing app using precise astronomical algorithms and user-friendly location management.

Precise Astronomical Calculations

Calculates exact sunrise and sunset times for any location using astronomical algorithms, then divides day and night into 12 planetary hours each.

Automatic GPS Detection

Automatically detects user location via GPS and calculates timings for their current position. Manual city selection also available.

City Database

Built-in database of thousands of cities worldwide allows users to check planetary timings for any location, not just their current position.

Home Screen Widgets

Glanceable widget shows current planetary hour and next transition time directly on the home screen without opening the app.
