Why we built the Orbit view
Every baby app shows you tables. We wanted to show you a feeling — your baby's whole day, at a glance.
Three steps. Zero overwhelm.
From tap to insight in seconds.
Log in 2 taps
Feed, sleep, diaper, medicine. Quick-log buttons at the bottom of every screen. Done before the baby notices.
See the pattern
The Orbit shows your baby's entire day as a 24-hour radial clock. Feeds, naps, and diapers — all visible at once.
Understand your baby
Smart stats and notifications learn your baby's rhythm. You'll know what's coming before the crying starts.
Everything your baby's day needs.
Track smarter, not harder.

How TandemBaby helps you see your baby's sleep patterns without turning you into a data scientist.
What "feeding every 3 hours" actually means
The real answer isn't a clock — it's your baby. Here's how to read the signals.
Questions & answers
Is my baby's data private?
Yes. All your baby's data stays on your device. We never see it, sell it, or share it. Our analytics use only anonymous, hashed identifiers through TelemetryDeck — a privacy-first European analytics provider. No ads, ever.
What ages does TandemBaby support?
TandemBaby works from birth through toddlerhood. The 72 milestones cover 0–24 months, and logging works for any age.
Does it work offline?
Completely. TandemBaby stores everything on your device. No internet connection needed to log, view stats, or see the Orbit.
Can I export my data?
Pro subscribers can export all data as CSV or generate a PDF baby report — perfect for sharing with your pediatrician.
What's included free vs. Pro?
Free gives you unlimited logging, the Orbit view, and basic daily stats. Pro adds full stats history, WHO growth charts, milestone photos, PDF reports, comedy notifications, and multiple baby profiles.
Can my partner use it too?
Partner sharing is on our roadmap. For now, TandemBaby is single-device. We're building sync that we're genuinely proud of — stay tuned.
