We’re not sure how or why Homeschool Panda is free. It provides for lesson planning, budgeting, calendaring, task management and assignments, connecting with other homeschoolers in your area, and much more. They have gone on record saying security is their top priority. You can work from a web interface or use the app for android or iOS. What’s more, they’re constantly rolling out new features. Maybe they’re thinking that, once they build a huge following, they’ll introduce ads or sell the app someday? Who knows. What we DO know is that, for now, it’s completely free of charge. If you or your missionary workers are doing home school, this is the go-to app to check out for your kids — and you.
