Wave was born (no pun intended) during a real contraction my wife was having. When my wife was in labor with our child, the app she was using hit her with a subscription popup — right in the middle of a painful contraction. Then another popup when she tried to edit a start time. All while ads sat at the bottom of the screen. During one of the most intense experiences of her life, an app was trying to sell her something. That's why Wave exists. Just one affordable payment. No ads. No popups. No subscriptions. Ever. Wave is a beautifully simple contraction timer that helps you and your birth partner stay calm, informed, and ready — from the first contraction to the last. HOW IT WORKS Tap once when a contraction starts. Tap again when it ends. Wave tracks the duration, interval, and frequency automatically — so you can focus on breathing, not buttons. FEATURES • One-tap timing with automatic duration and interval tracking • Edit any contraction's start or end time — no paywall, no popup • Clean, calming interface designed for use during active labor • Contraction history with averages and visual patterns • Dark mode for nighttime labor • Works offline — no internet required No "free trial" that auto-charges. No premium tier. No data selling. Wave is and always will be an affordable one-time payment because no one should be upsold during labor. Download Wave and have it ready before the big day.
