Strikr: Football Shot Tracker

How hard do you actually kick? Film it and find out.

Strikr measures a kick from video: how fast the ball left your foot, how fast it was spinning, and which foot struck it. Then it draws the flight over the replay. Record in the app or import a clip from Photos. Strikr finds the ball on the first frame, finds the kick in the clip by itself, and gets the scale from the ball. A size-5 ball is 22 cm on every pitch, so there is nothing to pace out or set up.

EVERY KICK • Ball speed in km/h or mph • Spin in rpm, read from the ball's own panels turning between frames. When the footage can't support it, Strikr says so instead of guessing. • Which foot struck it, worked out from your run-up. Tap to correct it. • How high and how far the ball went, with the flight graphed under the video • The trajectory traced over the replay, in the color you choose • The replay with the sound of the strike, at full speed or slowed right down

YOUR KICKS • Every kick is saved with its flight drawn on it. Search by name. Filter by speed, spin, foot, date or place, and sort by speed, spin or date. • Your own categories: training, match day, weaker foot, whatever you like • Personal records, speed and spin at a glance, and a map of the pitches you've played on • Import up to three clips at once

SHARE THE CLIP A video of the kick with the tracer, the speed and the spin on it, plus the sound of the strike, at full speed or in slow motion. You choose what goes on it. It's ready for TikTok and Instagram.

PRIVATE BY DESIGN • Every frame is analyzed on your iPhone. No account, no upload, no ads. • Anonymous usage counts help improve the app. One switch in Settings turns them off.

HOW TO FILM • Put the phone on a tripod, or prop it on something steady, and keep it level. The level line turns yellow and thickens when it is. • Get the whole flight in frame from the strike on, and keep the ball big in the picture. Film closer rather than further away. • Film from the side or from behind the ball. Both work. • Daylight and a ball with clear markings give the best spin readings. The filming guide in the app covers the rest.

How close the number is depends on the footage. A ball that stays sharp and large in the frame measures better than one that blurs or shrinks to a few pixels. When Strikr loses the ball, it tells you so, and why.
