Made for the parents who don't want another app shouting at them - simple and clean. Levi nursing and diaper tracker is a calm, beautifully simple tracker for feeds, diapers, and growth. Designed to be tapped one-handed in the dark, at the hours when you need it most. No streaks. No badges. No "you've missed your goal" guilt trips. Just the things you actually need to know. FEEDING • One-tap timer with left, right, or both • Auto-suggests the next side based on your last feed • Manual entry for the feeds you forgot to time • Today's totals: count, duration, time since last DIAPERS • Two taps to log wet, dirty, or both • Daily totals at a glance • 7-day trend so you can spot patterns GROWTH • Log weights with date and time • Current weight with change since the first entry • Soft growth chart so you can see the trajectory • Pick your units: lb / oz or kg / g PERSONAL • Set your baby's name and the app changes to match • Night mode that dims everything for 3 a.m. feeds PRIVATE — ACTUALLY PRIVATE Most tracking apps quietly sync your baby's data to a server. This app doesn't. There's no account. No email required. No cloud. No analytics. No third-party SDKs. No ads. No tracking pixels. Everything stays on your phone. We can't see your data because it never leaves your device. Delete the app and it's gone — no servers holding a copy, because there are no servers. We don't want to advertise to you. We don't want to upsell you a premium tier in the middle of a feed. We don't want to harvest your data. So we charge a dollar one time, and that's it. You own the app forever.
