Since we’ve started our reviewing, as you could already notice, some kinds of products were really special, almost favourite for us to describe. Calculators, for example.
      This one, called TrayKalk, couldn’t surprise me with anything, except only one feature. But this, for the first sight not so important, feature then converts into a serious advantage. Its icon is always on the lower bottom of your screen, and when you need to calculate something very fast, you can just click on it and then make your counting as you want. Though the interface is very simple and even looks a bit ugly, it’s very functional and convenient. All the operations are supposed to be done by clicking your mouse’s buttons. The program itself isn’t so good, as it could be, but the idea is excellent. TrayKalk is clear even for a beginner’s understanding. All you have to do is just to download, than install it – and after that just to enjoy your ability to count quicker than all of your mates. It requires Win95 and higher. Hurry up, till it’s free and available!
