Baton: Baby Tracker

Baton is a calm baby log for the night shift. Big buttons at the bottom of the screen, a dim night mode, and one log that both parents share. LOG IN ONE TAP • Breastfeeding timer that switches sides and remembers which side is next • Bottles (breast milk, formula or mixed), pumping, solids, sleep, diapers, growth and notes • Every save has a 5-second Undo; every time can be edited • On iPhone, pause, switch or stop a feed from the Lock Screen and Dynamic Island (Live Activity) • Home Screen and Lock Screen widgets SHARE THE NIGHT SHIFT • Invite your partner with a link: they see and add entries on their own iPhone or iPad • Your own iPhone and iPad stay in sync too • Sync goes through your own iCloud.
