Sprint App vs C4Timekeeper

Using the front camera, Sprint App automatically starts and stops a timer as you run by the device. With Sprint App you can make precise timing of your sprint, cone drill or any other kind of motion based performance. It’s super easy; place the device on the floor/ground and press ready. Using only one device, you can time a sprint from A-A, while adding another device you can time A-to-B. For an A-B run, simply open the app on both devices, and make sure you've enabled Bluetooth or/else WiFi (enable both for best performance). Wait for the synchronisation to complete, and you are ready to go. Setup works best when the device is positioned on the ground in a 45 degree angle. You should be able to trigger it from 0.5 to 1.5 meters in front of the device. Have fun – and don’t forget to send us your thoughts on hello@instinkt.dk or in the reviews.
