Duetling — Baby Tracker

Duetling — Baby Tracker The small hours, written down. Duetling is a calm, fast baby log for feeds, naps, nappies and growth — built for tired parents who need one tap, not a form. Open the app, tap once, done. Long-press any button when you want to add a detail like breast side or bottlr volume. THE WHOLE DAY IN ONE RING The home screen shows your baby's last 24 hours as a single ring — feeds, naps and nappy changes as marks around a clock face, with night hours shaded so the shape of the day is visible at a glance. The centre shows what you actually want to know: time since the last feed, and how long the current nap has run. MADE FOR 3AM Duetling works completely offline. Your log lives on your device and never waits for a network, so you can write down a feed on aeroplane mode with zero delay. At night the screen switches to a dark, low-glare layout with the Feed button front and centre — the one you reach for most. SHARE THE LOAD WITH YOUR PARTNER Invite the other parent with a short code. Every entry appears on both phones in the background, and each parent's entries are colour-coded, so you can both see who did the 2am feed. Partner sync is part of the one-time unlock. LOOK BACK Charts show feeds per day, nap totals, nappy counts and your baby's growth curve over time — your own measurements, drawn plainly, with no percentiles, no averages and no judgements. Duetling never tells you what a number means. YOUR LOG IS YOURS Export everything to CSV whenever you like. Delete your account and everything stored with it from inside the app, in one step. ONE PAYMENT Logging, your full history and CSV export are free forever. A single one-time purchase unlocks partner sync, charts and more than one baby. No subscription, ever. WHAT DUETLING IS NOT Duetling is a written record kept by a parent, not a health service. It does not diagnose, advise, interpret or alert. It offers no feeding, sleep or medical guidance, sets no schedules, reminders or treatment plans, and will never tell you whether a number is normal. If you are worried about your baby, speak to a doctor or health visitor.
