Two babies.
One app that actually keeps up.
Twinkle logs both babies at once — feeds, sleep, diapers — and shows them side by side. No more fumbling between profiles at 3am.
Free to download. Private by default — your data stays yours.
Every other app was built for one baby.
With twins you burn half your energy just switching between profiles — usually with no free hand to do it. Twinkle shows both at once, because that's how twins actually happen.
Made for the chaos of two
Every feature starts from the same question the other apps skip: what if there are two of them?
Both babies, one tap
Log a feed, nap, or diaper for one twin — or both at the same time. No toggling, no double entry.
Side by side, always
One timeline shows both babies together, so you can see who's in sync and who's drifting off schedule.
Two timers on your lock screen
Run a feed or sleep timer for each baby and glance at both from the lock screen — no unlocking, no app.
Who's due next
Twinkle keeps track of who ate last and who's coming up, so neither baby slips through the blur.
Trends for two
Combined and per-baby patterns for feeds, sleep, and diapers — the view your pediatrician actually wants for multiples.
Yours alone
Syncs between you and your partner through your own iCloud. No account, no ads — and we never see your data.
Built in the open, for twin families
Twinkle is made by an independent developer — not a faceless app factory — and shaped alongside real parents of twins. It's early, and that's the point: join now and you help decide what gets built first.
