A simple widget that turns the BTN1 of your Bangle.js into a one-button-tracker that can be used right from the clock face and everywhere else. Record when you're sneezing, yawning, eating, or whatever you think the button should track for you.

Every time you press & release the BTN1 from the clockface this widget will record the time you pressed & released. While you press the button the Bangle will briefly vibrate and the green LED in the display will light up while you're keeping the button pressed.

Once you release BTN1 both the start & end time of your button press will be saved in 2-column one_button_presses.csv CSV file on your Bangle.js. The CSV file can be downloaded from the My Apps tab on the Bangle.js app store.

To not interfere with alternative usages of BTN1 (eg when using it for menu navigation) you need to keep the button pressed for at least 130 milliseconds before it triggers a recording (the vibration & LED will inform you about having triggered it).

• Track whatever events you want with a simple button press on your wrist
• Track multiple things with a single button by using different length of button presses
• Easily export the data to visualize your presses in a tool of your choice

Only makes use of BTN1 (the top one) right now.
