About

Twin is a baby tracker made for parents of twins. Both babies sit side by side on one screen, so at 3 AM you can see who fed last, which breast is next, who is asleep and whose diaper was changed, without switching profiles. BOTH BABIES ON ONE SCREEN Each baby has a card in their own color: time since the last feed, a running feed with a Stop button, the next breast side, asleep or awake with today's sleep, the last diaper and today's wet and dirty count. The same screen shows today's feeds, bottle volume, sleep and diapers for each baby. ONE TAP PER BABY, OR ONE FOR BOTH Quick Log has Feed, Sleep, Diaper and Medicine buttons for each baby, plus a Both row that logs the same entry for both twins at once. A breastfeed logged for both puts each baby on the breast they are due. FEEDING - Start a timer that keeps running when you close the app, or log a finished feed with its start time and length - Left, right or both breasts, or a bottle of formula or expressed milk with the amount in ml or oz - Add a top-up bottle to a breastfeed: it stays one feed and counts toward the day's volume - Breast rotation suggests each baby's next side - Feeding a sleeping baby ends the nap, unless you switch that off for a dream feed SLEEP Log when each baby falls asleep and wakes up, and where they slept. Today's total includes a night that began before midnight and the nap in progress, shown against a target range for the baby's age. DIAPERS AND MEDICINES Log wet, dirty, both or dry diapers. Log a medicine or vitamin with its dose and time: the last dose shows as soon as you open the form, and one entry can log a medicine for both babies with a dose for each. GROWTH Log weight, length and head circumference and see both twins on one chart, with weight starting from birth weight. With a birthday and sex set, Twin shows WHO growth standard percentiles (birth to 24 months), using corrected age for babies born before 37 weeks. Units: kg and cm, or lb, oz and inches. HISTORY YOU CAN FIX Browse any day's feeds, sleep, diapers and medicines with clock times. Logged on the wrong twin? Tap the entry to change the time, type or amount, move it to the other baby, or delete it. SHARE WITH YOUR PARTNER Invite your partner from Profile. You both log and see the same babies and entries, each with your own Apple Account, synced through iCloud. REMINDERS An optional reminder 2 to 4 hours after each baby's last feed (you choose the interval), and an optional summary of the day at 8 PM. FREE Everything above, for two babies. Dark mode follows your iPhone, and text grows with your iPhone's text size. TWIN PRO - Tandem feed clock: one clock for both babies, sides from each baby's rotation, swap sides mid-feed, finish each baby separately - Schedule Sync: how much of the last 7 days your twins spent feeding and sleeping at the same time, week by week - Pediatrician Report: a PDF of the last 7, 14 or 30 days with feeds, sleep, diapers, medicines, growth and a day-by-day table, ready to share - AI Twin Guide: ask about feeding, sleep and routines with twins. Answers take your babies' recent numbers into account (age, weight, feed, sleep and diaper totals), never their names. Twin asks your permission and names the AI provider before anything is sent. General information, not medical advice: ask your pediatrician about your babies' health. - Triplets and more: add a third baby and beyond Twin Pro is a monthly or yearly subscription that renews automatically. The price is shown in the app before you subscribe. Cancel any time in your App Store account settings. PRIVATE No account to create. Your logs are kept on your iPhone and in iCloud. The AI Twin Guide sends a question and your babies' numbers only after you allow it. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
