MPTAS is a great companion to MasjidPrayerTimes by Xalting. It can be used as a standalone indicator of whether the Adhan was called or not at Masajid or it can be paired with the MasjidPrayerTimes app to create a highly useful masjid signage display. Data can be uploaded via mpt.xalting.com by users that have access to the Xalting MPT web portal.
