About this app
Twin is the only baby tracker built for two — track BOTH babies on ONE screen with a side-by-side dual dashboard showing feeding status, sleep status, and diaper status at a glance. No more switching between profiles at 3 AM. THE DUAL DASHBOARD Open the app and instantly see: which baby is hungry, which one needs a diaper change, who slept longer, and whose turn it is for which breast. The 5-second answer that saves 20 minutes of guesswork. FEED TRACKER Log feeds per baby with start time, end time, breast side, and notes. The Breast Rotation Tracker automatically keeps track of which baby gets which breast next — essential for balanced milk supply when feeding twins. See today's feeds for both babies side by side. SLEEP TRACKER Track who's sleeping, who's awake, and total sleep for the day. Compare both babies' sleep patterns on one screen. See if your twins are syncing their schedules over time. DIAPER TRACKER Log wet and dirty diapers per baby. Pediatricians need diaper counts for newborn wellness checks — Twin makes it a one-tap log. GROWTH TRACKING Track weight, length, and head circumference independently for each baby. Each twin follows their own growth curve — and Twin tracks them separately.
