LaborClock
Time contractions in your browser — and never lose one
One big button: tap when a contraction starts, tap when it ends. Every tap is written to this browser the instant it happens, the 5-1-1 check tells you in plain language when it may be time to call your provider, and editing a mistimed entry is free. No ads, no account, no rating prompt mid-contraction.
Stored in your browser only. Nothing you do in the web version is sent to our servers. Clear your browser data and it's gone — so export a backup from the in-app menu if you want to keep it.
This app is a community proposal.
Try the full browser version now. We build the iPhone and Android app once 100 people upvote it.
We'll email you once, when it ships. Unsubscribe anytime.

What you can do in LaborClock on the web
Tap to time, saved instantly
The whole timer is one button. Length and the gap since the last contraction are written the moment you stop, so a refresh or a closed tab loses nothing.
The 5-1-1 check, spelled out
Three plain lines — about 5 minutes apart, about 1 minute long, for 1 hour — each ticking green as your pattern meets it, with a calm banner when all three do.
Editing is free, always
Tap any contraction to fix its date, start time or length; the gaps on either side are recalculated for you. Delete one, or add one you timed by hand.
A read-out for triage
Average length, average gap, longest contraction, the qualifying run, a length-over-time line and a minutes-apart bar chart — copy the whole summary as one sentence to read to the nurse.
Works with the signal off
No network connection is ever opened. Export a CSV of the run or a full JSON backup whenever you want.

Sound cue, the 5-1-1 banner, CSV export, backup, sample data and erase.

Questions
Is the web version of LaborClock free?+
Yes. Every screen is free to use: no subscription, no in-app purchases, no account.
Do I need an account?+
No. Open LaborClock and start using it right away. Sign in with Google only if you want to upvote an app, save it to your list, or leave a comment.
Where is my data stored?+
Only in this browser's local storage. Nothing you enter is sent to our servers, so we can't see it, back it up, or restore it. Clearing site data, a private window, or another device starts empty. Export a backup from the in-app menu to keep it.
Is there a LaborClock app for iPhone or Android?+
Not yet. LaborClock is a community proposal: the browser version is complete, and we build the iPhone and Android app once 100 people upvote it. Upvoters get one email when it ships.
