This app looks fun! Unfortunately, it seems like the site is down and not available anymore... I can suggest another one; if you like coloring with your kids, you can try this site: https://wunderkiddy.com/toddlers-activity/weather-2 . There are a lot of activities similar to those on the app, but they're done with real paper and pencils😀. (Check the menu at the top to see them all, if you want.)
