Baby Tracker App
Know more.
Worry less.
Tinylog is a baby tracker app for iOS and Android that logs feedings, sleep, diapers, and growth with 3-tap logging, AI care plans, and WHO + Fenton growth charts.
It's a lot to keep track of.
Your pediatrician asks how much your baby is eating, and you can't remember, because you're too tired.
You can’t remember when your baby last ate, slept, or had a wet diaper. It all blurs together.
You wonder if your baby’s sleep, feeding, and growth are normal, but have no baseline to compare.
“Parents who track worry less”, JMIR mHealth, 2019

Common questions
Is my data safe?
Yes. Your data is encrypted and stored securely. We never sell or share your personal information.
Does it work for twins or multiples?
Absolutely. You can add multiple babies and track each one independently with their own care plan.
What happens after the free trial?
You can continue using basic tracking for free. Upgrade anytime for care plans, trends, and caregiver sync.
Can both parents use it at the same time?
Yes — that’s what caregiver sync is for. Invite your partner, nanny, or family and everything updates in real time.
What if I switch phones?
Your data is tied to your account, not your device. Sign in on any phone and pick up right where you left off.
