Quick log
One tap, and it's written down.
Twenty-four trackers ready to go, each with the fields that actually matter — which side, how much, how it went. Sleep and tummy time run as timers you can start and forget, and every sheet opens with 15m ago and 30m ago, because you rarely have a hand free at the time.

Track anything you like
Physio exercises, reflux drops, contact naps. Invent a tracker and it gets a real form, real validation and its own place in the timeline — exactly like the ones Buma ships with.
Sleep
It gets better. Here's when.
Babies can only stay comfortably awake so long. Buma counts forward from the last wake-up and gives you the window that's likely to work — then sharpens it every time you log a nap.
- The next window, not a guess
- A time range you can plan the afternoon around, worked out from her last few days rather than a chart in a book.
- Settling, tracked
- How hard she was to get down is the earliest sign the wake windows have drifted. It shows up in the log before it shows up in the cot.
- The long view
- How long she'll sleep unbroken, week by week. It's the number most parents wish someone had shown them.
Patterns
Every day, side by side.
One row per day, weeks of them at once. It's the view where a regression stops being a feeling you can't prove and becomes a shape you can point at.
- Weeks, not yesterday
- Scroll back as far as you've logged. A fortnight of naps breaking up is visible at a glance instead of reconstructed from memory at midnight.
- One tracker at a time
- Show only sleep, or only nappies, and Buma draws that tracker's days on their own with an average across them.
- Tap a day, open the day
- Any row opens the whole day behind it — every entry, in order, exactly as it was logged.
Sharing
Both parents. One baby. One history.
Send a link — or an eight-character code — and whoever joins sees everything, and can log and edit it too. No second account to reconcile, no screenshots at midnight, no "did you already give her the drops?".
- Everyone writes
- Mum, dad, a grandparent, a nanny. Every entry shows who logged it and who last changed it.
- Metric and imperial, both right
- One of you can work in millilitres and the other in ounces. Every total still agrees, because Buma keeps one real number and shows each of you your own.
- You decide who gets in
- An invite works once, expires within the hour, and you approve whoever uses it. After that they look after the family, log the days, or just read along — your choice.
Memories
The bits you'll want back later.
A photo, a line about what happened, and the day it belongs to. Add one and Buma tells the other parent, so it doesn't sit there waiting to be found.
- Kept beside the day it happened
- A calendar with the photos sitting on it, or a list if you'd rather. You find things by when they happened, which is how you remember them anyway.
- 42 occasions, no scoreboard
- First smile, first tooth, first time at the sea. Only the developmental ones carry an age range, those ranges are wide on purpose, and they only ever suggest what might be next — never that your baby is behind.
- Corrected age, quietly
- Say how many weeks early she arrived and Buma uses corrected age throughout, so nothing looks behind that isn't.
The other parent can just tap a heart
Six reactions, no typing. It's for the one who opens the app between meetings, sees the photo and has thirty seconds — and it is the smallest thing in Buma that people actually answer.
Ask Buma
The things you'd otherwise be googling at 4am.
Ask about her sleep, her feeds, whether the pattern is changing. Buma reads the log you already have and answers from it, instead of sending you to a forum thread from 2013.
- Answers with your numbers in them
- Not "naps often shorten around four months" — her naps, this week, against the fortnight before, and what you logged about how hard she was to settle.
- Share the chat, not a screenshot
- Turn one on and everyone in the family can read it and carry on asking. Each question shows who asked it, and the answers stay where both of you can find them.
- It remembers what matters
- Buma keeps short notes — a dairy allergy, the reflux drops, what worked last time — and reads them into every answer. You can add, correct or delete any of them.
Buma is not a doctor and nothing it says is medical advice. For anything that worries you, call one.
Growth
Growing, without a league table.
Weight, height and head size on one screen, against the WHO Child Growth Standards — drawn as a band showing what's typical, never as a rank.
- Their own curve, first
- The line Buma draws is your baby measured against herself over time. The typical range sits behind it as context, so a steady curve low in the band reads as steady rather than as a warning.
- Corrected age, on the chart too
- Born early and every point plots at corrected age, so the curve says what it should instead of looking late for months.
- A record, not a verdict
- Buma says so on the screen itself: it is here to keep the record, not to replace your baby's doctor. Growth worries belong with someone who can examine her.
Teeth
All twenty teeth, and when to expect them
Tap a tooth the day it comes through and Buma keeps the date. Each one carries the months most babies get it in — ranges taken from paediatric dentistry, wide on purpose, and no tooth is ever marked overdue.
Filled in here: the four that usually arrive first. Your own chart fills in as you tap them.

How it treats you
You'll miss days. That's fine.
No streaks. No red badges. Nothing to catch up on. Log what you can and Buma works with it.
- Built for a dark room
- Warm and dark by default, because a white screen at 3am wakes both of you.
- One hand, half asleep
- Big targets, timers you can start and forget, and a form that never asks a question it can answer itself.
- Nothing gets logged twice
- Tap it in a lift with no signal and it still lands once, exactly as you left it.

FAQ
Questions parents ask
What is Buma?
Buma is a baby journal for iPhone and Android. You log sleep, feeds, nappies, tummy time and anything else you invent — and both parents share one baby, so you're writing into the same history instead of two half-complete ones.
Can two parents really use the same baby?
Yes, and it's the point. One of you creates the family and sends an invite code; whoever joins sees every baby in it and can create and edit the same entries. Each entry records who logged it and who last edited it.
How do the sleep predictions work?
Babies can only stay comfortably awake so long. Buma counts forward from the last wake-up using a wake window that starts at what's typical for your baby's age and adjusts as you log real naps. It gives you a window to aim at, not a deadline.
What if I forget to log things?
Nothing happens. There are no streaks, no badges and nothing to catch up on. Buma works with whatever you managed to record.
Does it work if my baby was born early?
Yes. Tell Buma how many weeks early and it uses corrected age throughout — for wake windows, for milestone suggestions and for growth — so nothing looks behind that isn't.
Can I use my own units?
Yes. Millilitres or ounces, grams or pounds, centimetres or inches, Celsius or Fahrenheit. Buma keeps one canonical number and shows each of you your own units, so two parents on different settings still see totals that agree.
Is Buma medical advice?
No. Buma is a record-keeping app, not a medical device, and nothing it shows you — including anything Ask Buma says — is medical advice. Talk to a healthcare professional about anything that concerns you.
What does it cost?
Buma starts with a free trial, after which a subscription unlocks everything. One subscription covers everyone in your family rather than one per parent.
When can I download it?
Soon, on both the App Store and Google Play. Leave your email on our home page and we'll tell you the day it's out.
Can I keep photos in Buma?
Yes — that's what Memories is. A photo, a line about what happened and the day it belongs to, kept on a calendar you can scroll back through. Only the people you've invited to your family can see them, and adding one tells the other parent rather than waiting to be noticed.
What is the tooth chart for?
Tapping a tooth the day it comes through gives you a record of all twenty, and each one shows the age range most babies get it in. Those ranges are wide on purpose and nothing is ever marked overdue — teeth arrive when they arrive.
What languages does Buma speak?
The app is in 18 languages, and Ask Buma answers in whichever one you asked the question in. This website is in five so far.
