About

Dirty Knife Timer

Features
Read full description

This application is used to train quick-draw knife techniques, recording draw speed as a timer to enhance self-defense ability. We utilize the iPhone’s accelerometer to achieve this. Instructions: 1. Set your phone’s volume to maximum. 2. Set the countdown timer (can be a fixed time or random). 3. During the countdown, do not turn off the screen. Place the phone in your pocket. 4. When you hear the beep, immediately draw your knife. 5. The moment you come to a complete stop after drawing, the app will use accelerometer data to determine that you have finished the draw, thus calculating the time it took to draw the knife. Thank you to Matei Florin for inspiring me.
