Understanding Cycle Predictions
Lova uses your personal cycle history to predict future periods. Here's how it works.
How Predictions Work
Unlike apps that assume a 28-day cycle, Lova learns your unique pattern. The prediction algorithm analyzes:
Building Prediction Accuracy
Prediction accuracy improves as you log more data:
Import Your History
If you have data from another period tracker, importing it gives Lova instant history to work with.
What the Predictions Show
Predicted period dates
Highlighted range for your next expected period
Fertile window
Estimated ovulation and fertile days (if enabled)
Confidence indicators
How certain the prediction is
Why Predictions May Vary
Your cycle can be influenced by many factors:
Lova adapts to these changes over time, adjusting predictions as your patterns shift.
Improving Prediction Accuracy
Log consistently
Record your period as soon as it starts and ends
Add historical data
Import or manually add past cycles
Track symptoms
Some symptoms correlate with cycle phases
Log BBT
Temperature data helps confirm ovulation
All Processing On-Device
Predictions are calculated entirely on your device. Your cycle data is never sent to any server. The algorithm runs locally, keeping your data private.

When Predictions Are Wrong
If your period arrives earlier or later than predicted:
Don't worry about "wrong" predictions - they help the algorithm learn your real patterns.
