Your cycle and your deen, in one place.
Sila tracks your cycle alongside hayd, istihadha, prayer status, and Ramadan fast debt. Personalized to your madhab.
Free to join. We'll notify you when Sila launches.
Two worlds. No bridge.
Your period app doesn't know what hayd is.
Flo and Clue track bleeding. They don't know the difference between hayd and istihadha, and they never will.
You do the math in your head. Every month.
Is it day 10 or day 11? Can I fast tomorrow? You check your prayer app, then your period app, then try to remember.
Your fast debt keeps growing.
Every Ramadan, you miss days. The debt accumulates. There's no system to track it, schedule make-ups, or calculate fidyah.
One app that knows both sides.
Sila encodes the fiqh rules, hayd classification, madhab-specific timings, ghusl triggers, qada calculations, so you don't have to. Sourced from the works of Ibn Uthaymin, Ibn Taymiyyah, and Ibn Qudamah.
What Sila does for you.
Hayd or istihadha? Sila tells you.
Automated classification based on your bleeding pattern and your madhab’s rules. No more guessing.
“Can I pray today?” Answered instantly.
Open the app. See your status. That’s it.
Your madhab. Your rulings.
Hanafi, Shafi’i, Maliki, or Hanbali. Sila gives you rulings specific to your school, not generic advice.
Track your missed fasts across years.
See how many you owe. Schedule make-ups. Calculate fidyah. Don’t carry debt into next Ramadan.
Know when you’re pure.
Smart purity alerts based on your bleeding data. Resume worship with confidence.
Postpartum. Handled.
Nifas tracking with fiqh-aware purity alerts. Because new mothers shouldn’t have to research rulings on no sleep.

Built by someone who lived this.
Sila started with a frustration I couldn't solve. I tracked my cycle in one app, my prayers in another, and my fast debt in my head. When my husband and I got married and I wanted to track fertility too, I still couldn't find anything that handled both sides.
So we built it. He writes the code. I define the product. The fiqh research comes from primary sources: Ibn Uthaymin, Ibn Taymiyyah, Ibn Qudamah.
We're not a big company. We're a Muslim family building what we wished existed.
Questions you might have.
No. Sila is a tracking tool that encodes established fiqh rulings from recognized scholars. It classifies your bleeding based on your madhab’s rules and shows you your prayer/fasting status. It does not issue fatwas or replace consulting a scholar for edge cases.
All four Sunni schools: Hanafi, Shafi’i, Maliki, and Hanbali. You choose your madhab during onboarding, and all rulings are personalized to your school.
Yes. Your health and religious data is encrypted and never shared with third parties. We don’t sell data. Period.
Sila will offer a free tier with core features. Premium features like detailed fiqh explanations, advanced analytics, and partner sharing will be part of a paid plan. Pricing details will be announced before launch.
A Muslim husband-and-wife team. She defines the product from lived experience. He builds the technology. The fiqh research is sourced from primary texts by scholars like Ibn Uthaymin, Ibn Taymiyyah, and Ibn Qudamah.
