About Rhythm: Semen Retention
Count your days, handle urges in the moment, and see how your own body changes as your streak grows. YOUR STREAK, FRONT AND CENTER • Days since your last release, with milestones at Day 1, 3, 7, 14, 30, 60, 90, 180 and 365 • Best streak and your personal goal, set in a 3-question onboarding • Home Screen and Lock Screen widgets, plus Apple Watch complications URGE SOS When an urge hits, open a 1-minute breathing reset or a 10-minute delay timer — on iPhone or right on your wrist. Log the urge and what you did, so you learn your triggers.
