Your calendar tells you when you can expect your period every month!
You can choose different calendar views for the day or the month – and get predictions tailored to you. The more you track, the more accurate the predictions of when your next period will be!
Just remember though – Oky can only ever give predictions, and because girls often have irregular periods, these may not always be perfect!
Choose your Oky friend to guide you through the app, and choose your theme to make Oky yours!
You can change your Oky friend or theme whenever you like!
