Test your sprint speed and agility like a timing gate system, using only the camera on your phone. Metric Sprint turns your iPhone camera into a fully automatic speed and agility testing lab. No timing gates, no lasers, no wearables, no stopwatch. Set your phone up, run, and get instant peak velocity, 5m, 10m, and 20m splits across the entire sprint, and video playback of every rep. You can also test your change of direction and agility with a 5-0-5 and 5-10-5 test protocols. FULLY AUTOMATIC, START TO FINISH Most speed testing means hauling out timing gates, connecting to your tablet, managing dropouts, and battery. Metric Sprint does the work for you. It finds your body, automatically detects the start of each sprtin, and tracks your velocity in real time for frame by frame velocity analysis. Just line the video frame up with your run and the app handles the rest. MORE THAN A SPLIT …
Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be. The 10 screenshots above are Metric Sprint's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: Metric Sprint runs a dark set where the background shifts from screenshot to screenshot (first shot #2C6464) — each image has to stand on its own, so the captions carry more of the story. The accent colour we picked up, #5CCC84, is the one to reuse for badges, arrows and highlighted words if you borrow this look. Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
Notice the first screenshot in particular. It's the one users see in search results and on the product page, and it's where most apps spend their best caption and tightest design. Look at the proportion of background to phone, where the text sits, what one thing the image is trying to communicate.
