Slovník is a free Android application developed by Microton s.r.o. that falls under the Education & Reference category. It offers a vast dictionary database with over 130,000 translation pairs in English-Czech and vice versa. The range of words is comparable to a printed dictionary spanning several hundred pages.

The app also includes a wide range of idioms, phrases, prepositional phrases, and technical terms from all areas of human activity. The words are arranged in a single-column table, making it easy to read and without dense blocks of small or difficult-to-understand text.

The app provides a fast and convenient search function. By typing the first few letters of the word you are looking for, the app provides results that are progressively refined with each additional letter. You can easily find words that you're not sure how to spell, and the translations appear immediately without the need to navigate to additional screens.

The user interface is entirely in Czech, and all the necessary data is included in the application. No internet connection is needed to use the dictionary, and there is no need to purchase additional data. Whether you're at work, school, traveling, or reading an English book at home, Slovník will serve you well.
