Know where you stand,
every day

Your logs become clear answers on prayer, fasting and ghusl.

Can I pray today?

One sentence tells you if it's hayd, tuhr or istihadah, and what that means for today.

Answers from
your own cycle

Ask in your own words. It reads today's ruling straight from your logs, so the chat and the app always agree.

Every ruling
shows its source

Each ruling carries a source you can tap and read in full, approved by our scholar before it can be used.

Knows when
to say ask a scholar

If a question falls outside what it can answer from approved sources, it tells you so rather than guess.

Private by
design

Only the facts it needs for your question leave your phone. Never your raw logs, email or location, and never your husband's data.

And that's not all

flowdays also has:
