Sila: Muslim Period Tracker

Your cycle and your worship shouldn't live in separate apps. Sila puts them together.

What Sila does

Sila tracks your cycle, ovulation, and fertility, but it also answers the questions other apps leave to you. Is this hayd or istihadha? Do I pray today? Do I fast? Is it time for ghusl? Instead of bouncing between a period tracker, a prayer app, and your own memory, you open Sila and see where you stand.

With Sila, you can:

• figure out whether bleeding counts as hayd or istihadha based on your madhab
• check your prayer and fasting status for the day
• use Hanafi, Shafi'i, Maliki, or Hanbali rulings
• track missed Ramadan fasts, plan make-ups, and calculate fidyah
• track nifas after birth and get purity alerts
• get reminders when it's time for ghusl
• see cycle predictions based on your own history

Who built this We built Sila as a Muslim husband-and-wife team because this was already a problem in our home. She was tracking her cycle in one app, prayers in another, and missed fasts in her head. Then fertility became part of it too. We kept looking for one tool that covered both. It wasn't there, so we built it.

The fiqh logic is based on the works of Ibn Uthaymin, Ibn Taymiyyah, and Ibn Qudamah. Sila is a tracking tool, not a fatwa. If your situation is unusual or complicated, check with a qualified scholar.

Privacy Your data stays yours. Sila doesn't sell it, hand it to advertisers, or use it for targeting. No data brokers. No third-party analytics pulling in sensitive health data.

Why Sila feels different Most period apps stop at dates and symptoms. They don't help with hayd, istihadha, madhab differences, nifas, or fast debt. So month after month, you're still the one doing that mental math. Sila is built so you don't have to.
