You are probably looking for AlarmManager, which let's you start services / activities / send broadcasts at specific intervals or a given time, repeating or not. This is how you write memory friendly background services in android. AlarmManager is sort of like cron in unix. It allows your background service to start, do its work, and get out of memory.

You probably do not want to start an activity (if that's what you meant by "application"). If you want to alert the user that something has happened, add an alarm that starts a receiver at a given time, and have the receiver add a notification. The notification can open the application when clicked. That's less invasive than bringing some potentially unwanted activity to the foreground.
