CycleBox: Private Cycle

A period tracker that keeps your cycle on your iPhone, not in the cloud.

Most period trackers sync your most intimate data to a cloud account you do not control. CycleBox takes the opposite approach: it logs period dates, flow, and symptoms entirely on your iPhone, then projects your next cycle from your own history. It is a useful cycle calendar without turning intimate health data into another online profile.
