Track your cycle with clear prayer and fasting status.
Sila brings cycle tracking, hayd and istihadha guidance, prayer status, and Ramadan fast debt into one place, with guidance shaped to your madhab.
Free to join. We'll email you when the beta opens.
Private by design
Built for sensitive cycle and worship data.
All four madhabs
Guidance stays tied to the school you follow.
Tool, not fatwa
Clear daily guidance with room for scholar review in edge cases.
Start with the Hayd Calculator or browse the fiqh glossary.

Two worlds. No bridge.
Your period app doesn't know what hayd is.
Generic period apps can log bleeding. They were not built to help you tell hayd from istihadha.
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.
Where generic period apps stop.
Flo and Clue can still be useful for dates and symptom logging. This comparison is about the worship workflow Sila is built to keep visible.

The goal here is not to dismiss general trackers. It is to show the parts Muslim women usually still have to manage outside them.

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 applies published fiqh rulings from recognized scholars to the data you log. It helps you understand your likely prayer and fasting status based on your madhab, but it does not replace a scholar for personal, unusual, or edge-case situations.
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. Sila is built with privacy in mind for sensitive health and religious data. We do not sell your data, and we keep data sharing limited to what is needed to operate the product.
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 draws from published works by scholars like Ibn Uthaymin, Ibn Taymiyyah, and Ibn Qudamah.
