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.
Dr. Geo is an interactive geometry program that is distributed as a universal portable application. It allows one to create a geometric sketch and manipulate it according to its constraints. It is usable at home or at school, in primary or secondary education. It is simple and effective with extended features including scripting and programming.
KeePass is a light-weight and easy-to-use password manager that removes the need for you to remember many different passwords and makes it more feasible to use different passwords for each account. It manages your passwords in a secure database encrypted with AES and Twofish, which is locked with one master key or a key file.
Cura is a mobile phone application bundle of remote server administration tools. It provides a personalized terminal emulator, a syslog module that allows for reading logs directly from a server, a SysMonitor module that visually graphs CPU and RAM usage percentages, access to Nmap, and Server Stats will offer general server information like its Vitals, Hardware information, Memory information, processes, and so on. A security feature allows you to have Cura's database wiped when you send the compromised phone a secret pattern of your choosing. (e.g. send an SMS message containing "phone has been stolen!" to your Android phone to wipe Cura's database and receive the location of the compromised phone as an SMS to your emergency phone number or as an e-mail to your emergency email address).

SecuXabber is a secure Jabber-client for Android that uses strong, asymmetric encryption on top of the XMPP protocol. A key pair is generated on application start-up. Users can send their public key to other SecuXabber users via Bluetooth. This face-to-face check ensures the veracity of the public key. After the keys have been imported by both users, all communication between them is encrypted using strong 4096 bit encryption. It supports all relevant XMPP features, works with multiple accounts, is highly customizable, and has many other useful features.
