Sunrise, one of the best cross-platform calendar apps, finally shut down on August 31. If you're looking for a replacement, our friends at Zapier put together a cheat sheet to make the transition easy for you. Zapier looked at 18 different calendar apps, including some of the more popular ones like Google Calendar and iCal, as well as some little-known apps like Jorte and Digical. The cheat sheet serves as a quick comparison of what the apps feature, which platforms they work on and who they're best for.
Of course, we have our own recommendations for the best calendar app for iPhones and the best calendar app for Android. That said, just because it's the best doesn't mean it will suit all your needs perfectly, and if you're looking for alternatives, it's a list worth checking out.
