ЦеныСтоп is a free Android app that allows users to earn money by completing tasks at stores in their city. To get started, simply download and install the app, then register and fill out an application. Once you've completed a test task, you become a participant in the project.

If there are any available tasks in your city, the project manager for your region will contact you. Once you've completed the task at the store, you'll receive payment on your card. Payment for each task is made according to agreed-upon rates and depends on the volume completed, starting at 150 rubles or more.
