About this page

Why does this page exist?

Many websites already offer the same or similar tools to the ones Groupr offers, but the design of these sites are usually pretty outdated, and there is often not an easy way to directly access all these tools in one place. Groupr is the good-looking, easy-to-navigate alternative to those sites.

Groupr started off as a school project, but has since then received a lot of updates to create what I think is a great website, with lots of real-world use.

True random?

This site is not "true random", but this doesn't mean that the site is not worth using. For most purposes, psuedo-random, which is what a computer's way of creating random numbers is called, is enough. If you need a random result for professional lotteries, contests, drawings or for scientific purposes, I recommend RANDOM.ORG, a site that creates true random numbers with the help of atmospheric noise.
