Rhythmom - Contraction Timer

Time contractions with one tap. The 5-1-1 rule tells you when it's time to go. PDF reports, Apple Watch, widgets, family sharing — plus a birth announcement.

Rhythmom is a contraction timer designed for moms-to-be. Tap once when a contraction starts and again when it ends — the app records each contraction's duration and interval, and uses your contraction rules (such as 5-1-1) to let you know when it may be time to head to the hospital, supporting you until you meet your baby.

KEY FEATURES

• One-tap contraction timing Tap the ring to start, tap again to stop. Duration, interval, and today's count at a glance.

• Smart hospital reminders Built-in 5-1-1 and other common contraction rules, fully customizable for interval, duration, and pattern length. When your pattern meets the standard, the app alerts you — experienced moms can switch to the stricter 4-1-1 rule.
