Prayer time should feel like part of the room.

Ghroob turns the daily rhythm of prayer into a calm, living experience—on a phone, browser, kiosk, television, or an old screen given a new purpose.

The origin

It started with an Echo Show that deserved a better purpose.

I wanted a screen in my home that did one thing beautifully: make prayer visible. Not another feed, assistant, or dashboard—just the current prayer, the next one, and a gentle sense of time passing.

That personal experiment became a larger idea. Old tablets, televisions and smart displays already exist in millions of homes. Ghroob is an open foundation for turning any of them into a prayer-centered part of the space.

— Abdul Osama, creator of Ghroob

Local first

Your location, settings and prayer ledger belong on your device. The core works without an account.

Source aware

Calculation methods and local authorities are explicit. A time should never appear without a clear source.

Screen agnostic

The same prayer logic should serve a phone, Chrome tab, wall display, kiosk, television or repurposed device.

Open by design

The source is public under MPL-2.0, with contribution rules that protect privacy and asset rights.

One core, many surfaces

Build the prayer experience your space needs.

Ghroob separates prayer logic from the screen around it. Communities can improve calculation sources, interfaces, accessibility and device support without rebuilding the entire project.
