In CycloLab, a cycle is the plan that brings together the products you want to track, their periods of use, doses and times. It also gives your history context: each record belongs to a use scheduled in that cycle.
Think of it as a folder called “September tracking”. It contains the products and their schedules. Adding a product in Health alone does not create a schedule.
The app organizes the plan you enter; it does not choose a protocol. See how to create a cycle.
