Cyla - Period & Cycle Tracker

Cyla is the cycle tracker that actually learns your body - not the "average" body. Most period apps predict your cycle using basic calendar math. Cyla's AI engine analyzes your unique patterns, weighting recent cycles more heavily than older ones, to deliver predictions that get smarter every month. Even if your cycles are irregular. Your data never touches a server. Everything stays on your phone. ---- WHY WOMEN SWITCH TO CYLA ---- → Predictions that adapt to YOU Cyla doesn't assume you have a 28-day cycle. Its algorithm uses weighted averages for new users and outlier-resistant medians after 6+ cycles. Combined with optional BBT and cervical mucus tracking, predictions reach clinical-grade accuracy over time. → Know WHY you feel the way you do Cyla connects your symptoms to your cycle phase. Tired today? Your app shows you're in your late luteal phase — and that's normal. Breaking out? Cyla explains the hormonal shift behind it. It's like having a cycle-literate friend in your pocket. → Privacy that's architectural, not just a promise We didn't just write a privacy policy — we built privacy into the code: - AES-256 encryption on your device - No account or email required - No cloud storage, ever - No third-party trackers in the health layer - Anonymous mode for complete invisibility A subpoena to us would produce nothing. We don't have your data. → Beautiful enough to open every day Dark mode. One-tap logging. A cycle ring that shows exactly where you are. Symptom pills you can tap in seconds. Designed so you actually want to use it — not just another pink-butterflies app. ---- WHAT YOU CAN TRACK ---- - Period dates, flow intensity, cycle length - 50+ symptoms: cramps, headaches, bloating, breast tenderness, acne, digestive changes, and more - Mood and emotional patterns (5-point scale with illustrations) - Energy levels throughout your cycle - Basal body temperature (BBT) for ovulation detection - Cervical mucus changes - Intimacy and contraception - Sleep, exercise, and medications - Custom notes for anything else ---- AI ASSISTANT ---- Ask Cyla anything about your cycle.
