Daily Dashboard is a Windows Phone 8 app that is part calendar and part daily assistant. It offers easy access to your calendar appointments, birthdays, weather forecasts, Windows Phone details (battery level, available memory, etc.) and any alarms you have set. Designed for efficiency to give you a snapshot of what's going on in your life, the app has multiple views with a Home Page that sums up what's going on.
Daily Dashboard may be too busy for some but if you're looking for a one stop solution to keep tabs on your daily life, it is worth a gander.
