Most baby trackers were built for one person holding one phone. Then the second parent starts asking “when did she last eat?” by text at 3 a.m. Here is what a tracker for two parents actually needs, and which apps do it.
Full disclosure: Little Bean is our app, and shared care is the problem we built it for. We list it first for that reason. The rest of the page stays honest, including where another app is the better pick, for example if you want a tracker that is free forever.
What “for both parents” should mean
- Each parent has their own login. Not one shared password, not screenshots in a group chat.
- Every entry appears on both phones straight away. If one parent starts a feed timer, the other sees it running.
- Both parents get the same reminders. Whoever is awake can act on them.
- It works one-handed. The common action, a feed, a nap or a diaper, should be one tap from the home screen, because the other hand is holding the baby.
- It works on iPhone and Android. Many couples have one of each.
- Room for one more. A grandparent, nanny or daycare should be able to join without sharing a parent's account.
Five apps, compared
1. Little Bean · built for tracking everything together
Little Bean is built around one idea: the log belongs to the whole care team. Both parents are included on every plan, each with their own login. Every feed, nap, diaper and measurement appears on every phone in real time, running timers included, and every caregiver gets the same reminders. The common action is one tap from the Today screen, so you can log with one hand. Little Bean also learns your baby's rhythm from your own log: an estimate of the next nap, and an expected bedtime from your last seven evenings, with a reminder on both phones fifteen minutes before and a bedtime routine with calming steps.
It runs on iPhone, Android and Apple Watch in 16 languages, including Dutch and German, with data stored in the EU and no ads. The Family plan adds a nanny, daycare or grandparents: up to 5 caregivers and 10 babies.
The honest trade-off: there is no free-forever tier. New subscribers get 14 days free; after that Standard (both parents, up to 2 babies) is $35 (€35) a year or $5.99 a month, and Family is $50 (€50) a year or $7.99 a month. Advanced, $99.99 (€99.99) a year or $12.99 a month, has everything in Family plus First Foods, Room (a baby monitor made from a spare phone, with the loud-room alert going to every caregiver who has looked in) and 25 Ask Little Bean conversations a month. Get the app.
2. Robin Baby · best free sharing
Robin Baby is a newer tracker with a strong free plan: everyday tracking is free and ad-free, and sharing the timeline with up to 3 caregivers costs nothing. Premium adds an AI assistant, sleep predictions, a doctor summary and the Apple Watch app. The app and website are available in Dutch and German.
If paying for a tracker is a dealbreaker and three people are enough, Robin is a sensible choice. Little Bean's case is a larger care team on one plan, every caregiver on the same reminders, and weekly age-based guidance beside the log.
3. Nara Baby · calm and free
Nara Baby is calm, ad-free and free, with separate logins for caregivers and CSV export. For basic shared logging at zero cost it is a good start. The gaps show over time: trends cover the last 14 days, and there is no check-up report or age-based guidance. Little Bean vs Nara Baby in detail.
4. Huckleberry · best for sleep, weaker at sharing
Huckleberry leads on sleep predictions. For two parents the catch is sharing: you share one account rather than each having your own login, which gets messy once a nanny or grandparent joins, and the features most parents want sit in the paid plans. Little Bean vs Huckleberry in detail.
5. Baby Tracker · a solo log
Baby Tracker is a free, fast newborn log for one phone. It was not designed for two parents, which is fine if one of you does all the logging. Little Bean vs Baby Tracker in detail.
