It keeps the time itself.
Nida joins your Wi-Fi, learns your location and calculation method from the app, and from then on it needs nothing from your phone. Set it on a shelf and let it call.
A soft gold ring brightens in the minutes before each prayer and dims to nothing at night. No screen, no clock face.
A volume for each prayer, and a gentle ramp so the first note never startles. Fajr for one person; Maghrib for the house.
A physical mute on the back. Guests, a sleeping child, a call. Slide it, and Nida waits quietly until you slide it back.
Set up in a minute from the Speakers tab. Choose the voice, the prayers, the volumes. Then forget the app exists.
More than one Nida, each with its own prayers and volume. The bedroom hears Fajr; the kitchen does not.
Times update nightly over Wi-Fi. If the connection drops, Nida keeps calling from the month it already holds.
