Easily track your baby’s feeding times — together. With the Stillzeit App, you can easily log breastfeeding, bottle-feeding, or a combination of both. The clean, intuitive design helps you stay organized even late at night, without having to search for information. And if you don’t have a free hand, you can conveniently start recording via your Apple Watch or using Siri. Thanks to iCloud synchronization, data can be easily shared across multiple Apple accounts — so you’re always up to date while your loved ones can sleep peacefully. TRACK EVERY FEEDING Tap L or R to start timing a breastfeeding session. Switch sides on the fly — Stillzeit logs each breast separately. Track bottle feedings with volume in milliliters. Add optional notes to any session. Night feedings are labeled automatically. KNOW WHEN TO FEED NEXT Set your baby's feeding rhythm and Stillzeit shows a live countdown to the next feeding. A push notification reminds you when it's time — even on the lock screen. The next-side indicator tells you which breast to start on. SMART INSIGHTS Stillzeit learns from your data and surfaces personalized insights: - Side imbalance warnings if one breast is favored over the other - Short session alerts based on your baby's actual average - Cluster feeding detection when feedings bunch together - Long gap warnings when a feeding is overdue - Predicted next feeding time based on real patterns, not just a fixed timer - Daily bottle volume tracking 7-DAY CHARTS See your feeding patterns at a glance with daily duration charts, average feedings per day, longest sleep stretch, and bottle volume trends. SHARE WITH YOUR CO-PARENT Invite your partner via iCloud. Both parents see the same feedings, notes, and history — always in sync on both iPhones. No account to create, no email to enter. Just tap Share and send the link. APPLE WATCH APP Start and stop feedings directly from your wrist. The full recording interface runs on Apple Watch — left breast, right breast, bottle, notes, and volume. Recordings sync to your iPhone automatically. Perfect for late-night feedings when you don't want to reach for your phone. HOME SCREEN & WATCH FACE WIDGETS Glance at the next feeding time, which breast to use, and your baby's feeding status without opening the app. Available as iOS home screen widgets (small and medium) and watchOS complications (inline, circular, rectangular, corner). LIVE ACTIVITY & DYNAMIC ISLAND When a feeding is in progress, Stillzeit shows the elapsed time on your lock screen and in the Dynamic Island. Always visible, never in the way. SIRI & VOICE COMMANDS "Start feeding in Stillzeit" — hands-free recording when your hands are full (literally). Siri can also tell you when the last feeding was and which side was used. MULTIPLE CHILDREN Track feedings for multiple babies independently. Each child has their own feeding rhythm, history, and insights. PRIVACY FIRST All data is stored on your device and syncs only through your private iCloud account. No third-party servers. No analytics. No ads. BUY ONCE, USE FOREVER Stillzeit is a one-time purchase. No subscriptions, no in-app purchases, no premium tiers. Every feature is included from day one.
