ES - obchodní rejstřík ARES is an Android application developed by Martin Machata that allows users to search for economic entities, such as companies, individuals, entrepreneurs, and self-employed, in various registers, including Business Register, Commercial Index, statistical register RES, and DIC findings (if the VAT payer). The application contains identical information to that offered on the web portal ARES (mfcr.cz), with relevant and comparable details.

The application enables users to search for economic entities based on ICO, name and surname of the person, or company name. For companies, it shows all available data stored in the Commercial Register, TR, and RES, while for persons, it provides a clear statement of economic entities in which the person works. Users can also locate the found entities on Google Maps, including the residence of a person, company headquarters, etc., and determine their location. Furthermore, the application offers the possibility of storing the listing in pdf format and sharing it.
