As mobile applications developers, MetaQuotes Software Corp. would like to know, what platforms our customers use. Unfortunately, there is no such data concerning our branch yet. Therefore, we have decided to fill that gap. Previously, we had to use the reports of well-known analytical companies. But in most cases, such reports provide only sales volumes in some particular countries and throughout the world without revealing data concerning each definite business branch. At the same time, each business sector may have its own peculiarities affecting the customers choice and the state of the whole sector. So, we have decided to carry out this survey to overcome the mentioned issues. If you have a smartphone or a tablet PC, please take part in our survey. Your opinion is very important for us and it will definitely have influence on the development of our mobile applications.
