Olanna Health period tracker
Why Olanna
Engineered for Individual Baselines
Phase-Aware Daily Guidance
The platform identifies the current menstrual phase each morning, providing physiological context and evidence-based guidance rather than generic reminders.
Streamlined Logging
Keep a period log and symptom diary with entries for flow, mood, pain, energy, and sleep. Your records help you notice recurring patterns across your menstrual cycle.
Actionable Health Trends
Build a period history and explore cycle insights from your symptom entries. Patterns in your records can help you prepare questions for future medical consultations.
Privacy-First Architecture
AI summaries are processed and stored locally on the device until explicitly shared. Data privacy is foundational; user information is never monetized.
PMOS, PCOS & Endometriosis
Track irregular cycles, missed periods, and pain in one place. If you live with PMOS (previously called PCOS) or endometriosis, your symptom history can help you prepare questions for your healthcare professional.
Clinical Summaries
Create a cycle report from your period history and symptom records to share with your doctor. It supports conversations about your health, rather than providing a diagnosis.
Your four phases
Biological Rhythms, Decoded
Rest & Recover
The body's natural baseline resets during this phase. Energy conservation and recovery are the primary physiological priorities.
Rise & Initiate
Characterized by climbing hormone levels. This phase typically supports sustained focus, increased cognitive stamina, and new physical output.
Peak & Engage
Hormonal peaks often correlate with maximum energy and sociability, creating an optimal window for high-engagement tasks and collaboration.
Wind Down & Reflect
As energy levels naturally taper, the physiological focus shifts toward low-impact routines, steady tasks, and required recovery.
The app
Notice your cycle. Understand yourself.
Olanna Health is a private period tracker and period tracking app: a calm space to log your periods, track symptoms, and notice patterns in your mood, energy, sleep, and pain. Meet Lanna, your menstrual cycle companion.
What you can do
Use Olanna as your menstrual cycle tracker and period diary. Record period dates, flow, cramps, mood, energy, sleep, and personal notes. Over time, your period log becomes a history you can refer to when discussing symptoms with your healthcare professional.
Learn about period and symptom trackingMeet Lanna
Lanna is your lotus companion, checking in with you through every phase of your cycle. She's not here to diagnose you or guilt-trip you into logging every single day — just gentle nudges to help you understand what your body might be doing, and a reminder that checking in with yourself isn't extra, it's the whole point.
Your data stays yours
Your health information is personal — we're not here to sell it, study it, or slide it into someone's ad targeting. Olanna is built local-first, so your data lives with you. This is a private, judgment-free space to build body awareness at your own pace.
The fine print
Olanna Health is not a diagnostic tool and does not replace professional medical care. Cycle estimates cannot confirm ovulation or pregnancy, and period tracking is not a standalone method of pregnancy prevention. Think of us as backup, not a substitute for your doctor.
"It's your cycle.— Lanna, your companion
We just help you understand it."
