Two Greeks developers, the Petros Doybantzis and Stelios Petrakis, they created the first application that removes the 'vertical videos'. The Horizon as called, allows the user to horizontally pulls video on his cell phone regardless of how he keeps the device, performing real-time alignment using measurements of gyroscope. The user can hold iPhone vertically, horizontally or even rotates while tugging, and the final video will remain horizontal! Horizon is available in the AppStore for 0.89 euros and as soon as it was released it became very popular worldwide.
