WeCroak is an Android App designed to remind the user that he or she is going to die.
Each day, we’ll send you five invitations at randomized times to stop and think about death. It’s based on a Bhutanese folk saying that to be a happy person one must contemplate death five times daily.
The WeCroak invitations come at random times and at any moment just like death. When they come, you can open the app for a quote about death from a poet, philosopher, or notable thinker.

Really Bad Chess is an game for Android that implements . . . well . . . really bad chess.
Really Bad Chess is just like chess, but with totally random pieces. Try 8 Knights, 4 Bishops, and 3 pawns — why not?

List My Apps for Android is one of those apps that fills a very niche purpose, but if you happen to need the functionality it provides, it is a godsend.
As the name suggests, the app simply outputs a list of all apps installed on your Android device in plain text, HTML, Markdown, etc.
I assume most people use this to share app list with friends, family or associates. I use this app every time I’m getting close to changing phones–with 568 apps on my phone and a lot of customizations surrounding those apps, I use it as the first part of generating a checklist of everything I need to do to get a new phone up and running like my old one.
