Like any other app you’d have on your smartphone or tablet, the calendar is a subjective and often polarizing choice. Several entries try to make sense of your schedule, and feed it to you in new and exciting ways. Or, they just show you what you’ve got going on. Whatever the app does, you’re probably going to have to look at it to see what’s going on, so aesthetics are important. Google’s Material Design overhaul brought some bright, bold visuals, and it could be coming to their iOS Calendar app.
