Порадник АТО is an Android application developed by Indigo Wind, which serves as an electronic collection of advice and useful information for mobilized soldiers in the Ukrainian army. The information presented in the app is taken from official guides that are issued during basic training and other open sources. The app is designed to limit its target audience to soldiers of the Armed Forces of Ukraine and National Guard, as all the materials provided are exclusively in Ukrainian.

The app includes a collection of advice for a victorious soldier, the experience of Chechen resistance fighters during urban battles in Grozny, pre-medical aid in the "red zone," and psychological assistance. In addition, it offers the ability to call the Ministry of Defense of Ukraine's hotline, materials on the use of alcohol during military operations, advice on communication rules in the ATO zone, catalogs of enemy chevrons and tactical signs, and technical data on weapons and equipment.

The app has a search feature for materials and a "Favorites" section. It does not require an internet connection or special permissions to function, and it does not contain any advertisements.

The developers plan to add new advice and data to the app, as well as a section with psychological self-testing and other features.
