Contraction timer & tracker

About this app

Contraction timer & tracker helps you time labor contractions with a single tap and understand what's happening at a glance — calmly, and completely offline.

When contractions begin, tap once to start and once to stop. The app records each one, shows your live duration and the time since your last contraction, and builds a clear picture of how your labor is progressing.

WHAT YOU GET
• One-tap start/stop with a big, live timer
• A running log of each contraction's length and the interval between them
• Rolling stats: average duration, contractions per hour, and frequency
• Trends: a labor curve, per-hour counts, a 12-hour density strip, and a frequency trend
• Gentle milestone alerts — "pack your bags" and the 5-1-1 "time to go to the hospital" rule — that you can fine-tune to your provider's guidance
• Choose to be alerted once, or after every contraction
• Share any chart or your full log as an image
• Six calm, accessible themes

PRIVATE BY DESIGN
Everything stays on your device. No account, no ads, no analytics, no tracking, and no internet connection required. Your data is yours — delete any entry, clear a session, or wipe everything at any time.

BUILT TO BE DEPENDABLE
Every contraction is saved the instant you tap, so nothing is lost if your phone dies or restarts mid-contraction — the timer picks right back up.

Not a medical device and not medical advice. The alerts are general heuristics to help you stay aware. Always follow your healthcare provider's instructions.
