Calendar
Your whole cycle on one calendar
- See when your next period is likely to start, and how far into your cycle you are.
- Period days, predicted days, the fertile window and ovulation are marked month by month, with a face on every day you logged a mood.
- Set or fix a period on a dial: its first day and how long it lasted.
- Ondiva starts from your answers. Once you have logged periods, it uses your own cycles instead.

Mood
Pick a face, from calm and happy to irritable, anxious or low. It shows on your calendar.
Symptoms and body
Cramps, headache, bloating, acne, fatigue, tender breasts, cravings, sleep and more.
Setup in a few questions
Your age, what you use Ondiva for, your last period, how regular your cycle is and what usually shows up around it.
A heads-up that stays on your phone
- An optional reminder two days before your predicted period.
- It is scheduled on your phone and says only “You have a reminder”, so your lock screen does not give it away.
Insights get sharper as you log
Your next three cycles with ranges, your cycle length against the estimate, the week ahead, moods and symptoms by phase, and a PDF summary of your cycles and symptoms you can share with a doctor. It is a summary, not a diagnosis.
Premium Insights and the doctor’s report.
Insights
Your next three cycles, with ranges
Each date comes with the range it may fall in, for the period, the fertile window and ovulation. The ranges narrow as you log more periods, because Ondiva uses your own cycle length instead of a guess.
Works from your first logged period and gets sharper with every log. Predictions are estimates, and the app says so wherever it shows one.
