The period tracker that never sees your data. No account. No cloud. No ads. Everything runs on your device. We built Perla after our wives got frustrated with trackers that sell data or blast ads. So we skipped the server entirely. The prediction engine, AI insights (Apple Intelligence), and fertility scoring all run locally. Apple Watch wrist temperature replaces expensive thermometers. Adapts to PCOS, endometriosis, pregnancy, and 8 birth control methods. $19.99/year or $49.99 lifetime.

Hey Product Hunt! I'm Matt, and my brother Patryk and I built Perla because our wives were fed up with period trackers that harvest data, show ads, and charge a fortune.
Our approach was radical: we just didn't build a server. There's no backend, no accounts, no analytics SDKs. Your cycle data never leaves your phone. Period.
What makes Perla different:
- 4-layer prediction engine runs 100% on-device
- AI insights powered by Apple Intelligence (no network calls)
- Apple Watch wrist temperature for BBT (no $150 thermometer needed)
- Adapts to health conditions like PCOS, endometriosis, perimenopause
- Transparent fertility scoring that shows you WHY, not just what

We're $19.99/year or $49.99 lifetime. That's 6x cheaper than the leading competitor, and we don't make you buy a thermometer.
As a thank you to the PH community, use code PRODUCTHUNT to get your first year for $14.99 (25% off).
We're fully bootstrapped, no investors, no board, no one telling us to monetize your health data.
We'd love your feedback. Ask us anything!
Super excited to finally share this with you all 🙌
I joined as a second founder because I immediately felt this had the potential to become something people actually use daily, not just try once and forget. Since then, we’ve been obsessing over making it simple, useful, and genuinely enjoyable.
Building in public and launching on Product Hunt means a lot to us, so your feedback (good or brutally honest) is more than welcome.
If Perla resonates with you, we’d love your support ❤️
And if it doesn’t, tell us why - that’s even more valuable.
Thanks for checking it out! ✨
