Contraction Timer by Nestling

Free contraction timer for labor — no paywall, no ads. One tap on your wrist or Lock Screen, built for the moment your bandwidth is lowest.

Contraction Timer by Nestling is the labor timer built for the moment your bandwidth is lowest. One tap to start, one to stop — on your iPhone, your Lock Screen, or your wrist. We handle the math, the gaps, and the durations so you can focus on labor.

TIME CONTRACTIONS WITHOUT UNLOCKING YOUR PHONE • Apple Watch app — start and stop contractions hands-free, even from the bath • Live Activity + Lock Screen — glance at the timer without unlocking • Ask Siri to start a contraction — completely hands-free timing • Huge one-tap buttons designed for active labor, not fiddly menus

KNOW WHERE YOU ARE • Automatic duration, gap, and median tracking for every contraction • 5-1-1 timing-pattern awareness — get a clear, calm note when your contractions are about 5 minutes apart, lasting about 1 minute, for about an hour • Intensity logging with a single tap after each contraction • Full session history — review past sessions, durations, and patterns

SHARE THE MOMENT, NOT YOUR PHONE • Partner share — send a live link so your partner, doula, or family can follow along in real time (up to 5 watchers) • Baby arrived — close out your session with one tap and optionally save it to Apple Health

YOUR DATA STAYS YOURS • iCloud sync — switch phones mid-pregnancy without losing a single contraction • No account required. No ads. Your timing data is never sold. • One-time Forever Unlock — no subscription, no auto-renew

IMPORTANT Contraction Timer by Nestling is a timing tool, not a medical device. It does not diagnose, detect, or predict labor, and it does not detect emergencies or provide medical advice. Timing patterns such as 5-1-1 are informational only — only your healthcare provider can tell you when to seek care. In any emergency, call your provider or 911 immediately.
