Getting started

Your home screen, fitted to you

The home screen shows what you are likely to need now; everything else is on the tabs. Its buttons change with your baby’s age — a newborn gets the breastfeeding timer, a toddler gets temperature and illness — and with how you feed.

The order follows your own habits. What you log most at night comes first at night, what you log most by day comes first by day. Within each half of the day the order stays put, so your thumb finds the same button every night.

Above the buttons there is one card at most: an appointment in the coming week, a reminder to write down the next one, your country’s care programme, or — once — Premium. The rest has its own screen.

Getting started

Day and night

By day Hodierna is bright and colourful, so the buttons are easy to tell apart. At night it turns calm: a darker page, softer colours and fainter buttons, so the screen does not glare at 3am.

It follows your phone’s setting. To choose yourself, open More → Settings → Appearance.

Every day

Writing things down

The home screen is the logbook. Feeds, nappies, sleep, growth and notes are each one tap, placed where a thumb reaches without shifting your grip, because the hand you have free is usually the only one.

Entries default to now, which is right most of the time. When you are catching up on something that happened an hour ago, change the time before you save.

The day view shows everything in order, with who wrote each entry. Corrections are made there — nothing is locked once it is saved.

Every day

The feeding timer, and which side

For breastfeeding there is a timer that records which side and how long. Start it, leave the screen if you need to, and come back — it keeps time while you are elsewhere in the app.

The home screen then tells you which side to start on next, taken from the last feed you logged. This is the smallest feature in the app and the one people mention most, because at 3am nobody remembers.

If you forget to start the timer, log the feed afterwards with a duration instead. Both end up as the same kind of entry.

Every day

Night Watch

Night Watch is a bedside alarm for a gap you choose. You set the interval — the app never decides that a feed is due, because it cannot know that.

It rings rather than notifies quietly, and it keeps checking that you actually got up: acknowledging it buys a few minutes rather than switching it off.

It needs permission to send notifications, and the phone only asks once. If you have refused, Night Watch cannot ring — the app says so plainly and arms nothing, rather than pretending. You can grant it later from Settings.

Every day

Statistics

The Statistics tab draws what you logged: the pattern of feeds, nappies, sleep and pumping across the days, trends over the weeks, and growth.

It shows what was written down, not necessarily what happened, and it never says whether anything is enough. For that, there is your midwife and your doctor.

Every day

Search and chat

Search finds any word you wrote — in a note, or the name of a kind of entry — on your phone, without a connection. It is under More.

The chat answers questions about your logbook in plain words. Its replies come from an AI model and are not medical advice; its screen says so.

Pregnancy

Pregnancy mode

You can start Hodierna while you are expecting. Give the due date instead of a birth date and the home screen follows the weeks: the baby, drawn for the week, its typical size as a fruit or an animal, and one line about the week.

Below it: your next appointment, your scans, and one Add button for everything else. The Pregnancy tab holds every tool, each with a line on what it does. When the baby arrives, the same logbook carries on.

Pregnancy

Week by week

Tap “Week … in full” on the home screen, or Week by week on the Pregnancy tab, and pick any week from the strip along the top.

Each week says what typically develops, what you may notice, and names its source with a link. It is the same text for every pregnancy at that week — never a reading of yours.

Pregnancy

Contractions, kicks and readings

The contraction timer: tap at the start and the end of each one, and it keeps the length and the gap. The kick counter counts movements in one sitting. Weight and blood pressure keeps your readings in one place.

They record; they do not judge. When to call is for your midwife to tell you — call whenever you are unsure.

Pregnancy

Scans

Add a scan from the home screen: photograph the print or pick it from your library. Hodierna crops it to the scan and keeps the whole photo a switch away.

Your newest scans appear on the home screen as soon as you add them. All of them are under Photos, on the Scans shelf.

Family and care

Appointments and vaccinations

Add check-ups, scans and vaccinations with a date, a time and a place. The next one in the coming week appears on the home screen.

Vaccinations follow your country’s programme: tick each dose off with the leg and the batch number, and add any the programme does not list.

Your app

Premium

The logbook is free for good. Premium adds document storage you can search by asking, the keepsake book, more photos a day, AI credits to start with, and it covers your household.

On the free plan up to 10 photos a day are uploaded; the rest wait safely on your phone and go up once there is room. When Premium switches on, Hodierna shows what is now open, one tap from each.
