Helpful information

Nelya includes clear explanations and links to recognised health information sources. This can help you learn more about periods, fertility, and menstrual wellbeing while reviewing your own cycle patterns.

Developed with privacy in mind

Nelya is developed by Apprecano Ltd in Finland. The app is designed to minimise the amount of personal information exposed outside your device. You stay in control of what you record, protect, export, or delete.

Simple pricing

Nelya is available as a one time purchase. There are no recurring subscription fees and no advertising.

Important information

Period, ovulation, and fertility estimates are based on the information you record. Individual cycles can vary, so predictions cannot be guaranteed. Nelya is not a medical device and should not be used as contraception or as a replacement for professional medical advice.

Your cycle is personal. Nelya helps you understand it privately, calmly, and on your own terms.
