StayHappy reminds you to keep your eyes on the good things in life.
The idea behind it is simple: a widget on your home screen constantly reminds you of a handful of nice little things that are coming up in the next few days. Today, it might be a special meal; tomorrow, the new episode of your favorite series; and the day after tomorrow, a hot bath. If you don't have anything, you'll be presented with happy moments from the past or a few items from your personal resource list.
