About

PeriSync

Features
Read full description

PeriSync is a cycle tracking mobile application that aims to go beyond the regular feature set of period prediction. The app operates with different modes of use in line with the use cases women use such apps for: because they want to be able to plan ahead by seeing predictions for their future periods; because they want to get pregnant and need data-based cycle information supporting that; because they want to monitor their health by logging their cycle data; or because they need help in keeping track of their contraception. PeriSync provides not only predictions but reports of all logged data, and live assistance all through one’s cycle based on user interactions. The insights and educational content provided follows the all-time most actualised scientific standards concerning women’s health. By providing these information PeriSync aims to empower women by knowledge about what’s healthy and what’s not, and give the decision to their hands about their own health.
