These applications are small, single-purpose utilities. They were originally developed for SkoobySoft's in-house personal use, and have been polished up for general release. Some of them have been considerably expanded due to user requests. Enjoy... and if you don't enjoy, write and tell us why.

If you have a broadband internet service with a monthly download limit, you may find SurplusMeter comes in handy. It measures the download and upload traffic on your Internet connection and keeps a record of your traffic volume. It gives you all kinds of useful output statistics, like daily allowance, average daily usage, accumulated surplus, and more.

Statistics are presented in three ways: simple bytes in/out; summaries of megabytes used and remaining, and graphic meters which display at a glance when you're getting close to exceeding your limit.

Privacy Note: SurplusMeter measures only the volume of traffic on your connection. It does not look at the content of data in/out or record where it comes from. Also, SurplusMeter is completely passive; it does not send any information to anyone.

SurplusMeter is freeware. It's open-source, released under the GNU General Public Licence. You can download the source code from our Downloads page.
