DayMaster is an online challenge platform offering guided, 14-day programs built around daily stories and practical activities. Each challenge combines a narrative voice or setting with small, structured steps to help participants explore a personal goal at their own pace. The first three days are free, and each full challenge costs 500 rubles.

The available programs address a varied set of everyday needs and interests. They include support for quitting smoking, a guided introduction to lucid dreaming, and daily prompts for noticing simple pleasures. Other challenges help participants work through a breakup, teach a puppy to stay home alone calmly, or approach toilet training with a child in a more relaxed way. Across the programs, DayMaster presents practical guidance through distinctive characters and story-led formats, aiming to make daily practice engaging and approachable. The platform is identified as a project by Igor Sterzhakov and provides sign-in and registration options for users who want to take part in its challenges.
