Summer is short and the calendar fills fast. SummerOS keeps the whole season in one private app on your laptop and phone. Every trip with destination, dates, transport, lodging, travelers, and a per-trip budget. Six summer budget categories - flights, lodging, food, activities, gas, souvenirs - planned vs spent live. A family bucket list with priority, target month, notes, and the joy of checking each one off. Four packing checklists - adults, kids, beach gear, road trip - tap to check off as you pack. A weekly kids schedule for camps, swim, library, soccer practice, plus screen-time rules with weekday and weekend caps. A light summer dinner planner and a chore rotation that ties to screen-time bonuses. Built-in road-trip games library and easy summer dinner ideas. The Dashboard rolls everything up - days to next trip, bucket-list progress, budget remaining, weekly reminders for sunscreen, hydration, and weather. No monthly subscription. No app for trips and another for packing and another for kids. One file, all devices, the whole summer.
