Earlier today the Cyanogen 12.1 build was released for OnePlus One owners. The update brings Lollipop 5.1.1 to the device along with several other changes unique to Cyanogen. One of those changes is the inclusion of the new Boxer Calendar app as the default calendar app.
For those who aren’t familiar with Boxer, they have for a long time produced arguably one of the better email apps for Android and recently released the Boxer Calendar app to complement it. The two apps interact well with each other and should provide a solid email and calendar solution for many users. For those who don’t have Boxer Calendar and are looking for a good calendar solution for your Android phone or tablet, you can get it in the Google Play Store.
