Salaat Time / Prayers Time is a FREE multi-function Islamic application that calculates the prescribed five daily Muslim prayer times as well as Qiblah direction for anywhere in the world. It rests in the system tray and at the prescribed times the Athan sounds and/or displays visual alerts. In addition you have a perpetual side-by-side monthly Hijri / Gregorian calendar which highlights important Islamic dates and moon phases.
