Cycle Tracking overview
How Cycle Tracking works in Pulsyn, what you can log, and how it contextualises your readiness without replacing medical guidance.
Last updated: July 13, 2026
Cycle Tracking is an opt-in wellness feature in the Pulsyn app. It lets you log menstrual cycle events, symptoms, and mood states, and helps the app interpret biometric shifts that naturally occur across the cycle.
What Cycle Tracking is not
Cycle Tracking is a wellness and self-awareness tool. It is not a fertility tracker, contraceptive device, or medical diagnostic tool. It does not predict ovulation with clinical precision, diagnose reproductive conditions, or replace advice from a healthcare professional.
Cycle regularity
Based on your logged history, the app classifies cycle regularity into one of four states:
- regular
- slightly irregular
- irregular
- insufficient data
The classification improves as you log more complete cycles.
Flow intensity
When logging a period day, you can choose a flow intensity:
- heavy
- medium
- light
- spotting
You can edit or remove a log if your observation changes.
Symptom taxonomy
You can log physical symptoms and mood/energy states for any day:
Physical symptoms
- Cramps
- Bloating
- Headache
- Tender breasts
- Nausea
- Back pain
- Acne
Mood and energy
- Happy
- Irritable
- Sad
- Anxious
- Neutral
- Energy low
These logs are stored on-device and are not used for advertising or shared with third parties.
Luteal-phase readiness adjustment
During the luteal phase, core temperature and resting heart rate typically rise slightly. When you have opted in and the app detects the luteal phase with sufficient confidence, it applies a small readiness adjustment to keep Readiness Score aligned with expected physiological shifts.
Other temporary contexts can also adjust readiness:
- Heat stress: elevated temperature, resting heart rate, and SpO2 dip.
- Altitude: sustained SpO2 drop with elevated heart rate over multiple days.
- Jet lag: a recent large bedtime shift can cap readiness while you adapt.
Using Cycle Tracking responsibly
- Log consistently for the most useful patterns.
- Treat predictions as directional, not exact.
- Talk to a healthcare provider about any symptoms or cycle concerns.
