MindMap is an application to create simplified mind map documents. It lets you build your mind map in a tree and view it as a graph. You can add details, calendar events, and tasks to nodes. If it contains email addresses or URLs you can click on them. You can add one picture attachment to a node. You can send your mind map file without attachments in email. You can also open mind map files from BlackBerry mail clients. Free Mind files can be imported and exported.
Loanr is a simple loan calculator. It's been tested on primary BlackBerry devices and Symbian devices. It's handy to have when looking to purchase a car from a dealer with their frequent jumping back-and-forth from total payments to monthly payments, but also works for other types of loans and less low-pressure situations. The file is unsigned, and may illicit a warning on your device when you try and download it.
