Video Delay films your movement and plays it back a few seconds later. Put your iPhone on a tripod, make your move, turn round: the action is on screen, and you never touch the phone. Built first for archery, it works anywhere the movement is over before you can look at it: golf, gymnastics, throwing, lifting, tennis, dance. THE DELAY • A delay you set from 3 to 20 seconds • A grid, and guide lines you draw on the picture to check a shoulder line or an arm alignment • A skeleton drawn over the athlete • Portrait or landscape, depending on where you stand the phone • No network, no account and no second device needed RECORD • A button to film what you see on the delay, saved to Photos with or without the grid, lines and skeleton • For archers, automatic recording: the app watches for your draw and records each arrow to Photos by itself • The iPhone's zoom and lenses ANALYSE YOUR SHOTS • A take mode at up to 240 frames per second, depending on your iPhone, with your takes kept in the app's gallery • For archers, every take is analysed: setup, anchor, string release, target impact, and your time at anchor • An approximate arrow speed, worked out from the sound of the release and the impact, once your distances are entered • A statistics screen: speed and time at anchor per session, personal best • Analyse a video from your photo library, up to 60 seconds REVIEW IN DETAIL • Zoom into a take • Lines drawn on the video that stay in place as you zoom • Share in one tap SEVERAL ANGLES ON A MAC Up to four iPhones film from different angles and send their picture to Video Delay on Mac, which shows them side by side, each one delayed.
