No ads and no account required for the timer. Personal Apple history stays in your private iCloud; browser history stays on this device.
Sync that fits your family
The timer always works offline. Personal iCloud Sync keeps your own Apple devices in step for free; Live Partner Sync lets up to five people coordinate instantly.
Best for your own Apple devices
iCloud updates automatically on its own schedule, so changes may not appear instantly.
Best for partners, doulas, and family
Your subscription supports the secure real-time relay. Personal iCloud data never passes through it.
The local timer and 5-1-1 guidance never depend on a subscription or a network connection. Live Partner Sync will be offered in the native apps, with the current price shown before purchase.
The 5-1-1 Rule
Contractions starting every 5 minutes or less, measured from the start of one to the start of the next.
Each contraction lasts approximately one minute in duration, a sign of strong, active labor.
This pattern has continued consistently for at least one full hour. Between Contractions tracks it for you automatically.
