Endless Calendar is an offline calendar app for Android that allows the user to create schedules and birthdays. This app is perfect for those who prefer to have their data saved on their device (offline) without the need for an internet connection. However, it should be noted that this calendar does not support Social Media or Cloud Services like Facebook or Google calendar.

One of the issues that users may face is with the notifications not working. To prevent the OS from killing the notification service, users should make sure that the energy optimization for Endless Calendar is deactivated in the settings under Battery Optimization.

Endless Calendar is a free app developed by daboApps and falls under the category of Business & Productivity.
