"Дневник кающегося" is a free Android app developed by Peacemakerv for the Lifestyle category. It is designed to help believers keep track of their confessions. The app is made to order by followers of the School of Repentance in Yekaterinburg.

The app has a database of sins that can be edited, and all new sins entered are saved in it. The numbering at the beginning of each line makes it easy to classify sins as per your preference, including for searching. The app offers both general confessions and daily confessions, which can be created as many times as needed and combined into a general confession. You can search the list by typing in the search field.

The app's main menu can be accessed by tapping the "+" button, and existing lines can be selected with a short touch. The app sorts the lines in the database and confessions alphabetically. When inserting lines without numbering, the app adds "0.0" to the beginning of the line, which is displayed at the top for editing. You can copy the finished confession lines to the clipboard or send them by email for printing before visiting the church.

The app requires Internet access for the webview that displays the Help text.
