Best Nappy Tracker Apps UK (2026): Log Wet and Dirty Nappies in One Tap

A good nappy tracker app lets you log a wet, dirty or both nappy with one tap, shows today's totals at a glance, keeps feeds in the same place and lets a partner log from their own phone. If you want something to hand the health visitor, an export helps too. Most baby trackers log nappies, but they differ a lot in how much detail they record and what they charge for it.

Full disclosure: we make CubTrack, so it is in the list. We checked the other five on the UK App Store and the developers' own sites in October 2026, and we have tried to give each its real strengths.

The short answer: For wet and dirty nappies with no paywall, CubTrack, Onoco and Baby Tracker (Nighp) all log nappies on a free plan, and CubTrack and Onoco let you add a partner free. If you want to record poo colour and texture on a nappy entry, ParentLove says it does that on its developer site. Huckleberry and Feed Baby log nappies too, but their store listings say little about the detail.

Why do parents track nappies in the first weeks?

Because wet and dirty nappies are one of the ways the NHS says you can tell a breastfed baby is getting enough milk. Its guidance says that in the first 48 hours your baby is likely to have only 2 or 3 wet nappies. From day 5 onwards there should be at least 6 heavy, wet nappies every 24 hours, and from the fourth day at least 2 soft, yellow poos the size of a £2 coin each day for the first few weeks (NHS: how to tell if your baby is getting enough milk).

At 4am, with a baby who has just fed, nobody remembers whether that was the third or fourth wet nappy. A tally on your phone answers it in a second. The NHS also says it can be hard to tell if a disposable nappy is wet, which is a good reason to write it down when you do check.

We keep the numbers by age in how many wet and dirty nappies a baby should have, and what each poo colour means in the baby poo colour guide. This post is about the apps.

What makes a good nappy tracker app?

These are the things that matter once you are actually using one, mostly in the dark:

• One-tap logging. Wet, dirty and both as big buttons, saved immediately, with a way to undo a mis-tap.
• A place for a note. Something to record "paler than usual" or "very runny" so you can describe it later.
• Daily totals at a glance. You should not need to scroll a list and count.
• Feeds and nappies together. The two are linked in the early weeks, so one app is easier than two.
• Sharing with a partner. Ideally on their own login, so both of you can log without passing a phone around.
• An export. A summary you can show a health visitor or GP.
• Price. Nappy logging is the basic job, so it should not sit behind a subscription.

Best nappy tracker apps compared (UK, October 2026)

Prices are what the UK App Store lists in-app, checked on 14 October 2026. Google Play prices can differ.

CubTrack: one-tap wet, dirty or both

CubTrack's Nappies tab and the Today screen both open a sheet of three large buttons: Wet, Dirty and Both. A tap saves the nappy at that moment, even offline, and a message offers Undo and Edit. If you want to add a time, a note or a photo, "More details" opens the full form. There is no separate colour field, so a colour goes in the note. The app also has a potty mode with Wee, Poo, Both and Accident for toddlers.

Today's totals show on the daily summary as, for example, "3 wet · 2 dirty", with a nappy that is both counted once in each. Nappies sit beside feeds and sleep in the same app, and the Android home screen widget has a Nappy button and shows the time of the last one. Nappy logging is free, as is sharing with one partner on a separate login, and the PDF report for your health visitor can include nappies. The app is written in UK English, so it says nappy throughout.

Where it falls short: there is no trends graph, no Apple Watch app and no import from other apps. CubTrack is on the App Store, and the Android version is on Google Play.

Huckleberry

Huckleberry is best known for sleep, and it is polished. Its UK App Store listing describes a "one-touch baby tracker for sleep, nappy changes, feedings, pumping, growth, potty training, activities and medicine", and the developer says caregivers can all log from a shared account. Its free tier covers basic logging tools and reports.

The strongest features, such as SweetSpot sleep predictions, are paid. We could not confirm from the listing or the developer's pages whether a nappy entry has a colour or notes field, so check in the app before relying on it. Plus is £10.99 a month or £64.99 a year, and Premium is £12.99 a month or £105.99 a year. The developer also offers two weeks of free access to advanced features.

Baby Tracker (Nighp)

Baby Tracker - Newborn Log is a long-standing, simple app. Its listing says you can "log wet, dirty, and mixed nappies" and see when the last nappy change was. Logging is free, but the free version shows ads. Remove Ads is £4.99, and Plus is £5.99 a month or £49.99 a year.

The listing doesn't mention a colour field. For partners, the developer's FAQ says sync works across iOS and Android, but it recommends the separate paid Baby Tracker Pro app for family use, so check what you need before paying for either.

Feed Baby

Feed Baby is built around breastfeeding, with timers and sides. Its listing says you can "record Diaper and Nappy changes with a single touch", with a separate dry-nappy option. It does not describe wet and dirty as separate options, or a colour or notes field, so it is a feed app that also counts nappies rather than a nappy-first tracker.

It is free to download. Unlock Everything is £5.99 and Unlock All is £6.99 on the UK App Store. If feeds are your main worry, our best baby feeding apps comparison covers it in more depth.

ParentLove

ParentLove is the one that goes furthest on nappy detail. Its developer site describes quick wet and dirty logs that record colour, texture and amount, with flags for leaks and accidents. The App Store listing says you can "record each wet or dirty diaper". Sharing with caregivers, unlimited history and multiple children are free.

The money works differently here: a one-off Pro for £14.99 or Pro Family for £24.99, plus add-ons such as Export at £5.99. That means exporting a report for the GP is a paid add-on or part of Pro. The developer's pages did not say whether the nappy tracker is free or paid, and ads are removed with the Ad Free add-on.

Onoco

Onoco's listing describes a "nappy & potty tracker" for monitoring nappy changes and potty training, and its site says unlimited tracking, including nappies, is free, with free caregiver invites. It also has an Apple Watch app. We could not confirm from the listing what a nappy entry records beyond that.

Premium adds nap predictions, a daily routine creator and CSV export, at £8.99 a month or £59.99 a year on the UK App Store. Onoco's own site lists Premium at £12.99 a month, so the price you pay depends on where you buy.

Is a free nappy tracker enough?

For most families, yes. The job is counting and noting, and most of these let you do it for free, though the free versions of Baby Tracker (Nighp) and ParentLove show ads. Paying makes sense if you want predictions, a longer history, extra carers or a full export. Our free baby tracker comparison sets out where each app draws the line, and baby tracking apps for both parents covers sharing. For the wider picture, see best baby tracker apps in the UK.

When should you call someone about your baby's nappies?

An app can only record what you see. These are the points where the NHS says to get advice, so please don't wait for the next appointment.

• You are worried your baby is not getting enough milk. The NHS says to ask for help early and contact your midwife, health visitor or a breastfeeding specialist. It also lists the National Breastfeeding Helpline on 0300 100 0212, open 24 hours a day (NHS: the first few days).
• Fewer wet nappies than usual with signs of dehydration. For a child under 5, the NHS says to call 111 now if there are signs of dehydration, such as fewer wet nappies. It says the same if you are worried about a baby under 12 months, or if your child stops breast or bottle feeding while ill (NHS: diarrhoea and vomiting).
• Pale poo or dark urine. The NHS lists pee that is dark yellow or brown, or poo that is a pale creamy colour, as signs to ask for an urgent GP or midwife appointment or call 111. It advises keeping a sample of the poo to show them.
• Jaundice and no wet nappies. The NHS says to call 999 or go to A&E if a baby with jaundice is sleepier than normal, not feeding, floppy or stiff, has a high or low temperature, has not produced wet nappies or has difficulty breathing (NHS: jaundice in babies).

Add a note and, if you can, a photo to the entry, so you have something to show the person you speak to.
