Universal Password Manager (UPM) allows you to store usernames, passwords, URLs, etc. in an encrypted database protected by one master password. Its three strongest features are simplicity (it provides a small number of very strong features with no clutter), the ability to run cross-platform, and database sharing. Rather than having many separate databases (home, work, etc.), database sharing allows you store your database at a remote location (password protected HTTP URL, for example) and then have UPM automatically keep your local database in sync with the remote database.

Asqare is a simple game for Android. The screen is covered with colored sprites (squares or circles). When you align three or more in a row, all adjacent sprites of the shape and color vanish. You can only swap adjacent sprites vertically or horizontally. You can swap sprites even if it won't result in a three-or-more alignment, but that will cost you 10% of your current score. The game offers two variations on the gameplay and manages a list of current games, which you can pause and recall at any time.
