Three things that keep happening in a house with a newborn

  1. Forgetting when the last feed was.

    Kept in your head, in a WhatsApp group, or in a notebook left at home.

  2. Caregivers out of sync.

    “Has the baby been fed yet?”

  3. Not being able to answer the doctor at a check-up.

    “How have their bowel movements been this week?”

Two taps

A diaper is logged before you have finished standing up

The home screen keeps the types you log most within reach — you choose which ones. Only got round to logging it ten minutes later? The time can be moved back as you save.

Six types have a color of their own

Color is never the only difference — every type always carries an icon and a label, so the timeline still reads if your eyes do not separate colors well.

  • Diapers

    wet, dirty, color, texture

  • Nursing

    a timer per side, last side remembered

  • Bottles

    ml, breast milk or formula

  • Sleep

    a timer that survives the app closing

  • Pumping

    the milk stash is used oldest first

  • Solids

    used from around the sixth month

Plus baths, growth against the WHO curves, temperature, medicine, immunisations, and free notes — those six are grey, told apart by their icon.

Your data does not go anywhere

Entries are stored in a single database file on your device. There is no sign-up, no sign-in, and no server holding them — the server has not been built yet.

  • The same data on your partner’s phone?

    Exchange a file — scan a QR code on the same WiFi, or send the file over chat. There is no server in between.

  • A waiting room with no signal?

    Every core feature works without the internet. Offline is the normal state, not a special case.

A Bayiku doctor report as a PDF

The monthly check-up

The doctor’s questions get answered from the screen, not from memory

Three days, seven days, thirty days, since birth, or a range you pick yourself. As the daily grid a doctor usually asks for, or as a list of every entry. It comes out as text, CSV, or PDF.

Bayiku is not a diagnostic tool

Bayiku records; it does not judge. If a pattern looks unusual, all that appears is a suggestion to see a health professional — never the name of a condition, and never a glaring red card for something that is normal for many babies.

The one who can answer questions about your baby is their doctor. This app gets the data ready.
