Chemicat Chemistry is a free Android application developed by Тимур Хасаров, designed to aid students and schoolchildren in learning the subject of Chemistry. The app contains a set of chemical calculators, teaching materials, and all necessary background information for the subject.

One of the most impressive features of Chemicat is its ability to calculate the molar masses of substances, including the exact molecular weight of even the most complex substances. Additionally, the app can determine the mass fractions of elements in substances, displaying how much of each element is contained in the substance. Chemicat can also read electronic configurations of elements and their ions, outputting the electronic structure of any chemical element or ion.

Another notable feature of Chemicat is its ability to allocate coefficients in reactions. Simply input a chain of transformations and the app will provide a list of chemical reactions involved in the chain. Furthermore, the app can solve chains of equations, making it an excellent tool for problem-solving.

Chemicat also includes tests and tasks to aid in the preparation and conduct of inorganic chemistry, with the full version offering even more problem-solving help. All functions are accessible without an internet connection, making it a convenient and comprehensive chemistry assistant.
