Calendroid is a replacement for the Stock Calendar from Android with a few added features.
-> Week Start Day settings
Allows you to set the start day of your week manually.
-> 1-14 day Multiday slider
Allows for easily zooming into a single day or out to see events surrounding the current day.
-> Colorized MonthView
This was lacking in the stock CalendarApp. Most people have more then one calendar and the ability to see what calendar has a scheduled event at a glance extremely helpful.
-> Horizontal Swipe(to the right) in Month view to go directly to the selected Multiday/Weekview
This makes it easier to go the the week overview display without having to use the menu selection
-> Event Searching
Now you can search your events from anywhere on the phone. Just use the search button on your phone to bring up you search.
-> Dim Past Events
-> Additional Settings
There are 2 versions.
