This App stores Appointments in a SQLite Database. Once an Appointment is captured, it will stay forever in the Database; as Appointment or in the Trash.
You can backup the Database Tables to the SD Card and restore from there. All Data is under your Control on the Smartphone.
Appointments can be shown in different ways. In the Overview a Calendar shows Months where every Day is colored. Green means one Appointment that Day, Yellow stands for two or three. And Red is four or more Appointments that Day. Clicking on a Day shows Details. You may look for the next Appointments as a List. Or you can see all Appointments grouped by Description. Which helps, if you have recurring Appointments. Clicking on an Entry let see all Appointments with the same Description. Another interesting View is to see all Appointments ordered by last captured Date descending. If you have a Typo in Date and wonder where the Appointment is, you can see it here immediate.
I wish a lot of Fun with the App.
