Eardex.com (short for Earth Index) was a free website to find, share and compare information on cost of living worldwide. It worked like a wiki for prices in all the towns and cities, regions and countries of the world. The Eardex database collected and displayed the local prices of more than 45 popular products which are available all over the world.
The website was based on the wisdom of the crowd principle: the data (i.e. local product prices) was provided by the users (User-generated content).
The website was free to use. A registration (also free) was possible but not mandatory. The site offered a lot of information for non-registered users, however, signing up was necessary to use all features. By signing up (email address required) a number of additional features became available, such as setting your preferred units of measurement and quantities for the listed products, the currency and the language for future visits.
Eardex.com was available in two languages, English and German. It was operated by Eardex.com GbR] which was founded in October 2011 (also the launch date of the website) by Fabian Walker and Steffen Schmeißer in Cologne, Germany. The website was privately financed and was developed and set up within one year, by up to four people working on it.
