TweakMASTER has been discontinued

We stopped selling TweakMASTER in February 2022. Windows now tunes its own network settings well enough that TweakMASTER's optimizations make little difference.

If you have a license, you can keep using TweakMASTER for as long as you like.

DU Meter

DU Meter, which came with TweakMASTER PRO, is still developed and sold. It shows your computer's Internet usage in real time, with reports and alerts. A TweakMASTER PRO license gets you a discount on the current version: get your upgrade.
