Participation in social research

I work for a social research company, and I could really use your help if you had an Android phone. The essence of the project is to install a pair of applications, one of which is a browser similar to chrome, the second is simply to collect statistics on what applications you use. If you go to the browser at least 1 time a week, every 3 months you pay 100 UAH, and an additional 100 UAH at the end of the year you go as a premium. That is, the total income for the year will be 500 UAH.
I would like to warn you that this is not network marketing, you do not need to buy anything or find people, but simply take part in social research by doing the above actions.
