Log a feed in two taps and everyone caring for your baby sees it before you've put the bottle down. BubSync is the baby tracker built for the whole care team: you, your partner, the grandparents, the daycare educator. One shared timeline, on every phone. HAND OVER IN ONE TAP, EVEN TO SOMEONE WITHOUT THE APP Send a 24-hour handover link by text or WhatsApp. Whoever is minding your baby opens a private web page: no account, no download. It shows the day so far, the last feed, nappy change and sleep, and the two things that matter: Care Essentials. Sensitivities and dislikes on one side, comforts and likes on the other. The white noise that works, and the dummy she'll take. Instruction Manual. Your "how we do things", with headings and lists. Bath, bedtime, the bottle routine. Write it once, then stop explaining it over the phone. The link expires by itself. If someone is staying, invite them into the family instead: live updates on their own login, never your password, and only the babies you choose. A BABY BOOK THAT FILLS ITSELF IN First smile. First tooth. The day she rolled over and nobody was filming. BubSync suggests the milestones that show up around your baby's age, and you can add your own. Photos and collages are free and kept on your phone. Memories come back framed like a polaroid with the date and age on them, to share as a card, not a screenshot. Record one and the family is told, so Nan hears about the first steps when you do. THE AI HUB One button, in the corner of every screen. Pick what you want and it answers from your baby's own logs, not generic advice. Day schedule: a realistic plan for today, built from this week's rhythm. Twins get one schedule, not two to reconcile. Sleep rhythm: what the naps and nights actually look like now. Play ideas: age-suited things to try, using what she already loves. Milestones to look for: what turns up around this age. Insights summary: a short read of the week's numbers. Edit anything before you keep it, then pin it to the timeline where every carer looks. TRACK EVERYTHING THAT MATTERS Bottle feeds, with amount and times Breastfeeding, with duration and side Breast pump sessions Diaper changes: wet, dirty or both Sleep and naps, with a live timer Night wakings Food, meals and solids Tummy time, with a stopwatch Notes, private or shared Milestones and memories Custom activities: medicine, therapy, anything, with your own fields and units Quick Log gets a feed down in two taps. At 3am, Night mode turns the screen near-black and warm amber, and one tap marks a waking. GROWTH AND DEVELOPMENT CHARTS Weight, length and head circumference against World Health Organization percentile curves. Born early? BubSync tracks corrected age on INTERGROWTH-21st preterm charts. Export a PDF for the appointment. INSIGHTS AND CHARTS Trends for every activity type across 1, 7, 30 and 90 days, or a range you pick. Switch between counts, durations and measurements. Export as PDF, CSV or JSON for the paediatrician. WORKS OFFLINE Log in a hospital ward, a car park, anywhere with no bars. Your baby tracker saves to the phone and syncs when you're back on signal. FREE AND PREMIUM Free: every built-in activity for up to two babies, your baby book with photos and collages, growth charts, handover links, and 1 and 7-day insights. Premium adds family sharing and cloud sync, the AI Hub, custom activity types, recording growth measurements, 30 and 90-day insights, PDF, CSV and JSON export, and photos that sync to the family. One month free. BubSync is not a medical device and does not diagnose anything. Talk to your GP, midwife or child health nurse, and tell carers about allergies directly. Your data is encrypted in transit, and you can delete your account and everything in it from Settings. Privacy policy: https://bubsync.com/privacy Terms of use: https://bubsync.com/terms
