Predictions
A window, not a guess

Questions
Is Ovra only for people diagnosed with PCOS?
No. Many people use Ovra while they are still looking for answers. Tracking your cycle lengths and symptoms creates the record a clinician needs to make a diagnosis.
How does Ovra predict periods when my cycle is irregular?
Instead of one date, Ovra shows a window based on your recent cycle lengths, with a confidence level. The window narrows as you log more cycles.
Does Ovra diagnose PCOS?
No. Ovra is a tracking and education tool. It helps you notice patterns and share them with your doctor, who can diagnose and treat PCOS.
Where is my data stored?
Your logs are stored on your iPhone. Ovra has no ads and never sells your data.
How much does Ovra cost?
Ovra is free to download and includes cycle tracking, daily check-ins and the core PCOS lessons. Ovra Plus unlocks every symptom pattern, the doctor report, weight and habit trends and the full library for $39.99 a year with a 7-day free trial, or $9.99 a month.
