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.
