BI Contraction Timer & Counter

A contraction timer for labor. Open it and press one
button - no sign-up, no onboarding, no permissions.

WHAT IT DOES
Press when a contraction starts, press again when it ends.
The app records the duration, the interval between
contractions, and tells you where you are: rhythm still
uneven, early labor, active labor, or time to go now.

After four timed contractions you get a first read. Most
timers just show numbers - this one tells you what the
numbers mean.

BUILT FOR THE MOMENT YOU NEED IT
- One big button. Nothing else on the screen.
- Nothing to set up. Install and start timing.
- Screen stays on while you're timing.
- Dark theme at night, follows your phone.
- Works offline. No account, ever.

HONEST ABOUT WHAT IT DOESN'T KNOW
This app never tells you that labor isn't happening.
Contractions can be irregular and still be real labor. When
the rhythm hasn't settled, it says exactly that - and keeps
watching.

FIRST BABY OR NOT
Thresholds differ. First labors: five minutes apart. Repeat
labors: seven - second babies come faster, and you need to
leave earlier. Set it once on the first screen.

FIX YOUR MISTAKES
Forgot to press stop? Resume the contraction and keep the
original start time. Pressed by accident? Undo. Any entry
can be edited or deleted - times, duration, intensity.

SHARE WITH YOUR MIDWIFE
Export the full log as a PDF or plain text and send it to
your doctor, midwife, or partner. Save it to your phone for
the hospital bag.

SEE THE PATTERN
A chart shows how contractions lengthen and intervals
shrink - the thing that actually tells you labor is
progressing. Switch the list between interval and rest time.

READ UP BEFORE IT STARTS
A short guide covers what contractions feel like, how to
tell Braxton Hicks from the real thing, and when to call.
Every claim is sourced and the sources are linked.

YOUR DATA STAYS PRIVATE
Nothing is collected about your labor: your contraction times never
leave your phone.

This app is not a medical device and does not diagnose
anything. It helps you time and record labor contractions,
at full term or earlier. Always follow the instructions of
your doctor or midwife, and contact them if anything
worries you.
