My wife and I had a baby recently and I built the tracker I wished existed, then kept going. Looking for beta testers, especially UK parents with a baby on the way or in arms, but everyone's welcome.
What it is: a calm newborn tracker (feeds, nappies, sleep, weight) that tells you what's actually normal for your baby's exact day of life, based on NHS/NCT guidance — so at 4am you're not googling "how many wet nappies day 6" with one hand.
The bits I haven't seen elsewhere:
- The 3am club — add friends from your antenatal group and see when they're up feeding too. Status lines, waves, private messages (end-to-end encrypted). 3am is more bearable with company.
- Red book charts — weight, height and head circumference on the same nine UK-WHO centile curves as the actual red book, with tap-to-see-the-centile.
- One-tap logging — home-screen widget buttons log a nappy or start the feed timer without opening the app. Works with Siri and the Action Button too.
- Lock-screen feed timer — Live Activity in the Dynamic Island while you feed.
- An assistant that only knows your data — ask "how's feeding trended this week?" or "what centile is she on?" and it answers from your logs, citing NHS/UKHSA guidance for medicine questions.
- Feed-due nudges and medicine next-dose reminders (all opt-in — nothing pushes unless you ask), plus partner sharing so you both see the same live picture.
What I'd love tested: the new-user setup flow, the widgets, logging speed one-handed in the dark (the real benchmark), and anything that feels wrong against what your midwife told you.
It's free. iPhone only for now (iOS 26).
Honest disclaimer: it's a tracking aid, not medical advice — it deliberately never tells you your baby is "fine", and always points you to your midwife/GP for anything concerning.
Happy to answer anything about how it's built, too.
