Track your cycle with clear prayer and fasting status.
Sila brings cycle tracking, hayd and istihadha guidance, prayer and fasting status, Ramadan fast-debt tracking, qada planning, ghusl reminders, and cycle predictions into one place, with guidance shaped to your madhab.
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.
Postpartum brings its own rules.
After birth, bleeding and purity questions are harder to navigate. Nifas tracking and fiqh-aware purity alerts keep the next step visible.
One app that knows both sides.
Sila encodes the fiqh rules, hayd classification, madhab-specific timings, ghusl triggers, fast-debt tracking, and qada planning, 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 classifies it.
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. Applied to your log.
Hanafi, Shafi’i, Maliki, or Hanbali. Status follows the school you chose, not a generic blend.
Track your missed fasts across years.
Log missed fasts, record make-ups, and plan qada repayments around your cycle.
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 look this up 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 madhhab information from named scholarly works to what 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 prayer and fasting status follows that 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 offers a free tier with core cycle tracking and worship guidance. Premium is optional, and the app shows current localized store pricing and any eligible introductory offer before purchase.
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.
