NestBoard

NestBoard is a family organizer app that puts your shared family calendar, chore chart, meal planner, grocery list and reminders on one board for the whole household. Instead of one parent keeping everything in their head and nagging, the board does the telling. The shared calendar shows everyone's schedule in one place and syncs with Google Calendar and Outlook, and you can export it as an .ics file at any time. Each person gets their own color, and repeating events, school days and activities stay organized week to week. Chores can rotate between kids on their own, with points and screen-time rewards that a parent controls. Kids can have their own profile without an email address, so even young children can see their tasks and check them off. Meal planning is built in. Import a recipe from a link, plan the week, and the ingredients feed straight into the shared grocery list. A pantry list helps you keep track of what you already have. NestBoard also tracks medications for everyone in the household, including bottles that are shared, with dose reminders and alerts. Event and medication alerts respect quiet hours. Robin, the built-in assistant, adds events and chores from plain language, so you can type "soccer every Tuesday at 5" and it lands on the calendar. Use NestBoard on a phone, in any web browser, or as a wall display on a spare tablet, an iPad or an Amazon Fire tablet in kiosk mode, so the whole family can see the day at a glance in the kitchen. NestBoard has no ads. We never sell your data and never use it to train AI. One flat price covers the whole household with unlimited members: $4.99 a month or $49.99 a year, with every feature included and a free 2-week trial with no credit card required. Available on the web, iPhone and iPad, Android and Amazon Fire tablets.

ParentPulse

Kids can send requests, and kiosk mode turns a shared tablet into a chore station. ParentPulse is free, with no credit card and no ads. ParentPulse+ ($7.99 a month or $59.99 a year for the whole household) adds an AI coaching briefing every Sunday, behavior trend insights, North Star Goals and Family Goals.
