Mobipark : Remote rental of devices to customers via the Internet for the following purposes:
1. Presentation of mobile products (games or software) by developers / salespeople in the webinar mode of the target audience.

3. Debugging graphics / code performance, testing the compatibility of work on different devices for developers.
