Preev is a web-based bitcoin value converter that enables its users to check the bitcoin exchange rate and convert any amount to or from their preferred currency.

The converter allows its users to keep an eye on the bitcoin price even while browsing in other tabs. Users of Preev are able to exchange bitcoins with euros, British pounds, Australian dollars, and Swedish kronas.

Preev collects prices from some of the largest bitcoin exchange sites and calculates the average bitcoin price from that and tells its users what the amount they entered will be worth on average. It also allows its users to select only one of the bitcoin exchange site prices, so if the site holds their bitcoins, they will have an idea about what they can expect to get paid for their bitcoins[1].

Preev was launched in 2011.
