Search "baby tracker app" and you'll get dozens of results, and nearly all of them claim to be the best. Instead of another generic list, here's a comparison based on real public information about each app — account requirements, what's actually free, and what each one offers — so you can choose with data.
What to check before choosing
- Account requirements — an extra username and password, or a more direct sign-up.
- What's actually free — a lot of apps show "free" on the store listing and hide the useful features behind a subscription.
- Whether it works offline — matters when your connection isn't always reliable.
- Whether it syncs with your partner — and whether that costs extra.
The apps compared
Huckleberry — best known in the English-speaking market. Free tier with basic sleep, diaper, feeding and growth logging; more advanced features (like SweetSpot sleep prediction or AI guidance) require a subscription, roughly USD 12–15/month. Requires creating an account to use, including the free tier.
Baby Tracker (Nighp) — translated into several languages. Its free plan includes most features: feeding, diaper and sleep logging, growth charts and PDF export, with automatic backup to iCloud or Dropbox.
Alfonso — no account: you share access with your partner via a link. Quick logging for feeding, diapers, sleep and baths, WHO percentile growth curves, vaccine schedule tracking and sleep prediction — all included, no charge. Works 100% offline.

Do these work for newborns?
Yes, all three work from birth — there's no separate "newborn" version. What changes at that age is what you use most: a breastfeeding timer, diaper logging every couple hours, and much shorter, more irregular sleep patterns than a few months later (here's the typical newborn wake window). Alfonso predicts the next feed and nap from day one, starting with typical ranges for that age and adjusting as you log — it doesn't need weeks of data to start being useful.

Which one fits your situation?
- If you want AI guidance tools and don't mind paying for the advanced features: Huckleberry.
- If you'd rather have something simple and don't mind syncing through a cloud backup instead of real-time: Baby Tracker.
- If you want to share logging with your partner without either of you creating an account, and you'd rather everything stay free from day one: Alfonso.
This comparison is based on public information about each app as of August 2026 — prices and features change over time, as with any piece of software. Worth double-checking each store listing before deciding.
