I'm launching Elif on Sep 21 - an ad-free app for prayer times, the Qur'an, qibla and dhikr. The part I keep rewriting is the assistant, and the problem is not the one I expected.
Religious questions have a property most product questions don't: for a large share of them the honest answer is "it depends which school of law you follow", and the four mainstream Sunni schools genuinely differ on real, everyday things. A model tuned to be helpful will flatten that into one confident answer. That is the failure mode I actually worry about - not hallucination exactly, but false confidence in a domain where people act on the answer immediately.
Elif brings your whole Islamic day into one calm, ad-free app: accurate prayer times with adhan alerts and a live lock-screen countdown, the full Qur'an with mushaf view, multiple translations and verse-by-verse audio, a qibla compass with AR mode, a dhikr counter, duas, and Ask Elif - an AI assistant that answers religious questions and shows the source it relies on. No ads, no tracking: your location is processed on device. Free on iOS and Android, in 7 languages.
