Lunar calendar Dara-Pro, developed by Rivendel, is a lifestyle app available for Android devices. This app offers a detailed guide to the phases of the moon, lunar days, and the moon's position in the signs of the zodiac.

One of the most impressive features of this app is its three modes of displaying information: for the current day, a more detailed weekly display, and a standard calendar month display. Additionally, users can search for favorable days in different categories such as haircutting, hair coloring, business events, sauna and massage, work in the garden, and much more. The app also allows users to set their location and supports both Russian and English languages.
