Cubby vs Nara Baby: which baby tracker is right for you?

All ages · Comparison · Reviewed 11 June 2026 · All articles

Choosing a baby tracker is one of those decisions that feels simple until you are actually using one at 3am with one hand. Cubby and Nara Baby are two apps that often appear on the same shortlists: both track feeds, sleep, and nappy changes; both have free tiers; both have been designed with a parent's actual day in mind. But they make meaningfully different choices around privacy, international support, app delivery, and pricing that will matter differently depending on where you live and what you care about most.

Quick verdict

Side-by-side feature comparison

Tracking the everyday: what both apps do well

At their core, Cubby and Nara Baby cover the same essential territory. You can log a breastfeed with the duration and which side; record a bottle feed with volume; note a nappy change and what you found; and start and stop a sleep timer. Both apps present this information in a daily view so you can see the shape of your baby's day at a glance.

Growth tracking is available in both apps, letting you record weight, length, and head circumference over time. Milestone logging is also supported in both, letting you note first smiles, rolling, sitting, and other moments as they happen.

For the majority of the day-to-day tracking that new parents actually need, either app will serve you. The differences that matter emerge once you look beyond the logging basics.

Privacy and data practices

When you use a baby tracking app, you are sharing a detailed record of your infant's health, feeding patterns, and sleep. That is genuinely sensitive data, and it is worth understanding how each app handles it before you commit.

Cubby's approach is to include no advertising, no third-party analytics SDKs, and no data sales across every tier, free and paid. This is a design choice that is reflected in the app's codebase, not simply a marketing statement. Parents who have looked at what is actually running inside Cubby find no ad networks and no telemetry tools from advertising companies.

For Nara Baby, you should read their current privacy policy directly on their website. Privacy policies change over time, and the definitive answer about data practices is always the current version of the company's own policy. As a general rule, when evaluating any baby tracking app, check whether the free tier is funded by advertising or data, and what third parties have access to logged information.

Vaccine schedule tracking: a meaningful difference for UK and international families

One of the clearest feature gaps between the two apps is vaccination tracking. Cubby includes the NHS vaccination schedule for UK families, the US CDC schedule, the UAE MOHAP schedule, and the German STIKO schedule. When you add your baby's birth date, Cubby calculates which vaccinations are due when and sends you reminders so you do not miss a jab.

Nara Baby does not include international vaccine schedules of this kind. For US families, this may not be a deciding factor. For UK parents, families in the UAE, or German-speaking families, the gap is substantial. Missing a vaccination because you forgot the exact timing is a real risk in the sleep-deprived early months. Having the schedule built into the same app you are already opening many times a day removes a meaningful point of failure.

If vaccination tracking is important to you and you are not based in the US, this is probably the single most important differentiator in this comparison.

App delivery: PWA vs native app

Cubby is a progressive web app. This means you install it onto your phone's home screen directly from a browser, without visiting an app store. It works offline, syncs in the background, and updates automatically without requiring a new app store download. This approach means Cubby works on any modern smartphone, regardless of which app store the device has access to.

Nara Baby is delivered as a native iOS and Android application through the App Store and Google Play. Native apps can take advantage of platform-specific design conventions that feel familiar on their home operating system. The trade-off is that you are dependent on app store availability and app store update cycles.

Whether this matters to you depends on your device and your preferences. Most parents find that a well-built PWA is indistinguishable from a native app in daily use. The important thing is that both apps work reliably and feel responsive at 3am when you are logging one-handed.

Family sharing

Both apps let multiple carers access the same baby's log. In Cubby, this is included at no additional cost regardless of which tier you are on. When a grandparent logs a bottle feed, you see it immediately. When your partner records a nappy change, the day view updates for the whole household. There is no need to upgrade to share with everyone who cares for your baby.

Nara Baby supports family sharing as well. Check their current plan structure to confirm how many carers can be added and whether this feature is available on the free tier, as these details vary and change over time.

The article and guidance library

Cubby includes a library of baby-care articles covering topics from safe sleep and starting solids to teething, milestones, and vaccination schedules. These articles source their information from NHS and AAP guidance and are reviewed by the Cubby editorial team. The idea is that the same app you open to log a feed can also answer a quick question about what a normal feeding pattern looks like at 8 weeks.

Nara Baby does not include a comparable editorial content library. If in-app guidance matters to you alongside logging, that is another area where the two apps differ.

Who should use each app?

This is not a competition where one app is the objectively correct answer. They are designed around somewhat different priorities:

• If you are in the UK and want NHS vaccine reminders built into your tracker, Cubby is the clear choice.
• If you are in the UAE or Germany and want local vaccine schedule support, Cubby covers those schedules; Nara Baby does not.
• If a no-ad, no-tracker privacy commitment matters to you at the app level, Cubby is built around that principle.
• If you want family sharing included in the free tier without checking plan limits, Cubby handles that by default.
• If you have a strong preference for native app design and primarily need US-focused tracking, Nara Baby is worth a trial.
• If you want in-app guidance alongside your logging, Cubby's editorial library covers sleep, feeding, milestones, and more.

Frequently asked questions

What is the main difference between Cubby and Nara Baby?

Both apps cover the core logging tasks: feeds, sleep, nappies, and growth. The key differences are in privacy approach, international vaccine support, and app delivery. Cubby is a privacy-first progressive web app with no third-party trackers, no ads at any tier, and vaccination schedule tracking for UK, US, UAE, and Germany. Nara Baby is a native iOS and Android app with a strong design focus and some features gated behind a paid plan. The best choice depends on whether you prioritise privacy and vaccine tracking versus native app design.

Is Nara Baby free?

Nara Baby offers a free tier that covers basic logging of feeds, sleep, and nappy changes. Some features are available on a paid subscription. Check Nara Baby's current pricing page for up-to-date plan details, as subscription structures change over time.

Which app is better for UK families?

Cubby is built with UK families in mind. It includes the NHS vaccination schedule with due-date reminders based on your baby's birth date, and its editorial articles draw from NHS guidance. Nara Baby is primarily US-focused and does not include NHS vaccine schedules. For UK parents who want vaccination reminders alongside daily tracking, Cubby is the stronger fit.

Can multiple carers log in the same baby account?

Both Cubby and Nara Baby support multiple caregivers sharing access to the same baby's data.

Check Nara Baby's current plan details to confirm how family sharing is structured across their free and paid tiers.

How does Cubby handle privacy?

Cubby does not include advertising, does not use third-party analytics SDKs, and does not sell user data. This applies across all tiers. When logging sensitive health and feeding data about your infant, it is worth checking the privacy policy of any app you consider, including both Cubby and Nara Baby.
