One medication record, two homes.
RxReminders reminds everyone who can give a child's dose. The first person to log it clears it for everyone, so nobody has to ask whether she already had something.
Both parents are reminded, and either can step off
A due dose reminds everyone who can give it. A parent can turn reminders off for their custody week, on alternate weeks, 2-2-3, every other weekend or weekly shifts, as long as someone else is still reminded. If nobody would be, they hear about it.
A sitter confirms a dose from a link
A babysitter, a school nurse or a co-parent on Android opens a link in any browser, with no account. It names the child, the medications and when the link expires. A dose confirmed there is logged under the name they type.
Each person sees only what they need
Share one child, not the whole household, at one of three levels: view, confirm a dose, or manage. Every share can be taken back from one screen.
