A focused contraction timer for iPhone and Apple Watch
Start the first contraction in the iPhone app or with a tap on Apple Watch. Once the session and Live Activity are active, the Lock Screen provides a read-only glance; use Start or Stop while the iPhone stays locked, without reopening the app. Siri is the only hands-free path and opens the app.
Completely free — no paywall, no ads, no subscription.
