Contraction Timer by Nestling

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. Completely free — no paywall, no ads, no subscription.

• 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

YOUR DATA STAYS YOURS
• No account required. No ads. No subscription. Your timing data is never sold.

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 local emergency services immediately.

From the makers of Nestling, the calm baby tracker. When baby arrives, your story continues there.
