From trying to pregnant, week by week, the NHS way.
Week by week with sea-creature sizes, your NHS journey checklist, help if baby moves less, a contraction timer, hospital bag and maternity leave.
In short: Splash pregnancy mode works out your due date from your last period, a scan date or an IVF or IUI transfer, then follows your pregnancy week by week with sea-creature sizes and a tip for your partner. It adds an NHS journey checklist (booking, scans, whooping cough, RSV and flu jabs, Healthy Start, MATB1), a Baby moving less? sheet with one-tap calling to your maternity unit, a kick counter, a contraction timer, a hospital bag list, a maternity leave helper, appointments and postpartum recovery notes. It is free, saved on your phone by default, and there is a gentle path if a pregnancy ends. It is information, not medical advice, and does not replace your midwife.

Week by week, your NHS journey, and help when it matters.
Week by week, sea-creature sized
Your due date from your last period, a scan date or an IVF or IUI transfer. Each week: how baby is growing, a note for you and a tip for your partner.

Your NHS journey, ticked off
21 steps from booking to birth preferences: the 12- and 20-week scans, whooping cough, RSV and flu jabs, Healthy Start and MATB1. First baby? The extra checks are added.

Baby moving less? Help in one tap
Save your maternity unit’s number for one-tap calling, with NHS 111, 999 and the signs that mean call now. Don’t wait until tomorrow.

A contraction timer that knows the guidance
Tap to time. See how many in the last 10 minutes, the average length and gap, and a prompt to call when they’re regular and close together.

Hospital bag, packed by 36 weeks
A checklist for you and for baby, from maternity notes to the car seat.

Maternity leave, worked out
When MATB1 arrives, when to tell your employer, and when Statutory Maternity Pay and 52 weeks would end. Your employer and GOV.UK have the details for you.

Is there a free week-by-week pregnancy tracker?
Yes. Splash pregnancy mode starts from your last period, a scan date or an IVF or IUI transfer. Each week shows how your baby is growing, compared with sea creatures rather than fruit (fruit is a tap away), with a note for you and a tip for your partner.
Your NHS journey in one list
21 steps of usual care in England, sorted into Now and Coming up: booking, the 12- and 20-week scans, whooping cough, RSV and flu vaccines, Healthy Start, MATB1 and birth preferences. Tick them off as you go. It is information to help you plan; your midwife leads your care.
Help when it matters
If your baby is moving less, call your maternity unit straight away. Splash keeps a Baby moving less? button at the top of pregnancy mode, with one-tap calling to your unit, NHS 111 and 999, and the signs that mean you should call.
Ready for the big day
A contraction timer that shows how many in the last 10 minutes and the average length and gap (on iPhone you can start and stop it from the Lock Screen), a kick counter, appointments, a hospital bag checklist, and a maternity leave helper for MATB1, telling your employer and Statutory Maternity Pay. All of it works offline.
After the birth
When baby arrives, Splash switches to postpartum recovery notes and when periods may return.
What happens if a pregnancy ends?
You can leave pregnancy mode quietly. Splash removes week-by-week content, keeps the mascot out of those screens and offers support reads.
Questions
How is the due date worked out?
From the first day of your last period, a scan date, or an IVF or IUI transfer date. It is an estimate; your midwife will confirm it at your dating scan.
What is the NHS journey?
A checklist of the usual pregnancy care in England: booking, the 12- and 20-week scans, whooping cough, RSV and flu vaccines, Healthy Start, your MATB1 form and birth preferences. Switch on First baby to add the extra 25, 31 and 40 week checks. Your midwife’s plan for you always comes first.
What should I do if my baby is moving less?
Call your maternity unit straight away, day or night. Don’t wait until tomorrow, and don’t use a home heartbeat monitor to check. In Splash, the Baby moving less? button is at the top of pregnancy mode, with one-tap calling once you save your unit’s number.
Does pregnancy mode use a different account?
No. It is a mode inside Splash. Your logs are saved on your phone by default, and are encrypted before any backup.
What happens if a pregnancy ends?
You can leave pregnancy mode gently at any time. Splash removes week-by-week content, keeps the mascot out of those screens and offers support reads.
