Contraction Timer Luma

When contractions start, you shouldn't be doing math. Luma is one huge button: tap when a contraction starts, tap when it ends. Luma reads the pattern — and tells you when it matches your go-to-hospital rule. ONE BUTTON, EVEN AT 2 AM A calm, night-friendly timer built for one-handed use. Tap to start, tap to end. Accidental taps are easy to fix, and a gentle breathing cue keeps you company through each wave. KNOWS THE 5-1-1 RULE Choose the rule your midwife or doctor recommends — 5-1-1, 4-1-1, 3-1-1 or your own. When your contractions match it for the sustained period, Luma tells you clearly and calmly that it may be time, and can call your birth partner in one tap. TIME FROM YOUR WRIST The Apple Watch app turns the whole watch face into the button. Tap your wrist when a wave begins — no reaching for your phone. A Live Activity keeps the session on your lock screen for your partner's glance. SEE THE PATTERN Every contraction becomes a bar: length, spacing, trend. Watch them get closer together, share a one-page PDF report with your care team, and keep every session stored privately on your device. No account. No cloud. No tracking. ONE-TIME PURCHASE. NO SUBSCRIPTION. The timer is free forever. Unlock the hospital-rule alert, Apple Watch, full history and PDF reports with a single purchase — no weekly subscription for a two-week moment. Luma is not a medical device and does not provide medical advice. Always follow the guidance of your midwife, doctor or care team.
