Simple Timecode Calculator is a little tool to help you perform add, multiply, divide or subtract calculations on video files using most frame rates. The app has a built in ticker tape function, which activates when you rotate your device to the landscape orientation. To assign the value currently presented on the screen to one of the two memory buttons simply press and hold one of them and the value will appear on the button. Simple Timecode Calculator works on all iOS 8 compatible iPhones.
