About this app

One View Calendar is a new kind of simple calendar app where everything is done on a single main screen.
You can enter events in large text and view them clearly. Setting reminders is incredibly easy, too.

Super Simple by Design
Double-tap control is used throughout: select a date, start entering an event, or set a reminder—all with a double tap.
Since everything happens on one screen, there's no accidental swiping or screen switching. Checking and adding to your calendar is smooth and stress-free.

This app intentionally excludes syncing with other calendar apps.
Instead, it focuses on letting you input events, view them in large text, and receive reminders—making it a simple fusion of a calendar and to-do list.

Note: Up to 4 events can be entered per day.
