Women's Health & Cycle Tracking — Core vs. Complete ExplainedUpdated 3 days ago

QRNT gives you cycle tracking built directly into the QALO app — no separate subscription, no third-party app required.

Core Women's Health (QRNT Original) 

Basic cycle phase detection using skin temperature and heart rate data. Predicts your period and provides general phase insights.

Complete Women's Health (QRNT Slim) 

Deeper insights across all four cycle phases — menstrual, follicular, ovulation, and luteal. Includes:

• Symptom logging and a daily journal
• Fertile window estimates
• Hormone-shift detection via skin temperature
• Personalized tips for training, nutrition, and energy based on your current phase
• Cycle predictions powered by your unique biometric data, not population averages

Everything lives inside the QALO app for simplicity and privacy. Your data is not shared with or integrated into other women's health apps.

Period Prediction

QRNT uses continuous skin temperature and resting heart rate patterns to detect the hormonal shifts that signal the start of a new cycle phase. Based on these patterns, the app predicts when your next period is likely to begin.

Predictions are powered by your individual data — not population averages — which means they improve over time as the ring learns your unique rhythms. For the most accurate predictions, wear your ring consistently, especially during sleep when the most useful baseline data is collected.

QRNT Original provides period start predictions based on skin temperature and heart rate data. QRNT Slim adds full four-phase predictions with symptom logging and hormone-shift detection for a more complete picture across your entire cycle.
