Lock Calendar is a utility for your iPhone, that lets you easily track your calendar events on the lock screen. This provides you quick access to your next ten upcoming appointments without opening an app, in fact without even unlocking the lock screen.
This really brings joy to Treo and WM users who are used to seeing the upcoming events on the home screen.
The app doesn’t come with any launch icon. Just install the app, and your calendar entries will start to show up on the lock screen.
There is a little bug in the software, that shows you entries a day in advance. This is expected to be fixed in the next upgrade to the software.
