Plan the whole homeschool year in minutes, then just check off each day. Tell Lesson Garden how many lessons or pages are in each book. It works out the pace, spreads everything across your school year, and gives you a simple checklist for every child, every day. EVERY BOOK FINISHED ON TIME • Enter a book's lessons or pages, and Lesson Garden spreads them evenly so it finishes on the last day of school. • Prefer a routine? Choose every day, Mon–Thu, Mon/Wed/Fri, Tue/Thu, every other day, or your own days, and see the finish date for each before you pick. • Page-based books get the right number of pages each time. • Curricula with more than one book, like Math 2A then 2B, are planned as one year. • Already partway through? Start from the lesson or page you're on. A CHECKLIST FOR EVERY CHILD • Today shows each child's lessons for the day. Tap to check them off. • The Week view shows the whole week at a glance, on iPhone and iPad. • Filter by child or by book. LIFE HAPPENS, AND THE PLAN KEEPS UP • Missed a day? Unfinished lessons move to the next school day, and the rest of the plan shifts. • Worked ahead? Mark the next lesson done and everything moves up. • Checked something off by mistake? Undo it. YOUR SCHOOL YEAR, YOUR WAY • Set your first day, number of school days (180 by default), and which weekdays you do school. • Add breaks and holidays, and plans flow around them. • Give the same book to more than one child, each with their own copy to check off. • Doing history or a read-aloud with everyone? Make it a together book: it shows up once, and one tap checks it off for every child. HANDY EXTRAS • Home Screen and Lock Screen widgets show what's next and each child's progress. • An optional daily reminder tells you how many lessons are planned that day. • On Apple Watch, see today's lessons and check them off from your wrist, with a lessons-left count on your watch face. LESSON GARDEN PLUS The free version plans for up to 2 students. Lesson Garden Plus adds: • Up to 8 students. • Family Sharing: both parents sign in (with Apple, or with an emailed code) and share the same plans and checkmarks on their iPhones and iPads. Plus is available yearly (with a free trial) or as a one-time lifetime purchase, and can be shared with your household through Apple Family Sharing. Your plans stay on your device unless you turn on Family Sharing. No ads, no tracking. Terms of Use: https://www.lessongarden.app/terms.html Privacy Policy: https://www.lessongarden.app/privacy.html
