Teeeello is a free multimedia application designed for iPhone users to control the TELLO toy drone by Ryze Tech. With Teeeello, users can experience flying a drone by simulating an actual flight control stick through their iPhone. While the app allows for capturing photos, video support, specifically FPV, is currently not available. Users can choose between two types of control sticks - normal and gesture-based, providing a unique and immersive flying experience.

By connecting to TELLO's WiFi, users can access features like panorama photo mode and auto flight control. The app enables users to perform functions such as take-off, landing, altitude control, and panoramic photo capture. Additionally, users can customize settings for unit preferences, stick types, and altitude limits, enhancing their drone flying experience.
