⚠ Educational only — not medical advice. Consult your healthcare provider.
How to use Contraction Timer
- Tap to log the start of each contraction.
- The tool calculates frequency (time between contractions) and duration automatically.
- Use this pattern, along with your doctor's guidance, to help judge when to head to the hospital.
Limitations
- This tracks timing only — it's not a substitute for guidance from your OB or midwife about when to seek care. If you're unsure, call your provider rather than relying on the timer alone.
