Newborn records app that is free and useful

Hello :) Would like to hear from mummies your recommendations on any free apps that is useful for recording newborn feeding schedules, pee/poop, routine etc. that can be shared together with husband’s phone? Am giving birth soon and think it’s easier to have such records that my husband and I can share to track and get used to baby’s routine :) Thank you for sharing! #firsttimemom
