iGLIDER QuiZ аналитика приложений для 20 мая

This application allows you to revise important subjects (weather, piloting, equipment, regulations, flight mechanics) to prepare your theoretical certificates of free flight (paraglider, hang glider), whether it is the initial (green level), pilot (blue level) or confirmed level (brown level) ! You have access to the entire database. For those who don't want ads, an in-app purchase allows them to be removed. Indispensable to revise everywhere!
