My very big tablet (Cozyla digital calendar)

Thanks to a ridiculous amount of "influencer" adds and videos pushed into my feed, we now have a set up my husband calls our hotel check in kiosk. I've got two kids in B&M school, 1 kid homeschooled, all 3 competitive gymnasts with 3 different practice schedules, private teaching, college teaching, an afterschool program, a youth orchestra, and all the household management stuff including meal planning, grocery shopping, and indoor and outdoor chores.
I chose this over a Skylight or Hearth because it's just a giant android tablet, so I can use homeschool planet, sweepy, emeals, and google calendar. I tried using their calendar and chore app, but the calendar was having sync issues and the chore app is not as robust as sweepy. I haven't tried to dig into the meal planning app yet, since we've been using emeals for several years already.
But, being able to open homeschool planet on the big screen during school time, then sweepy during chore time, then having the calendar page open the rest of the time has been really nice.
This is just the 15.6" screen, but they have bigger ones. I figured we'd try this less expensive one to see if it's useful and upgrade if we felt like a bigger one would be useful. I could see this one being useful in the if we did want to upgrade, but I don't feel the need to have a bigger screen. It came with a hefty stand that works in landscape or portrait but since two of our apps run in portrait, we keep it that way.


What is homeschool planet? Can you use your own curriculum and plans or is it something pre-planned? I'm very intrigued for my 4 homeschool kids.
