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.
