-# Widget Name
+# The One Button tracker
 
-Describe the app...
+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. Record when you're sneezing, yawning, eating, or whatever you think the button should track for you.  
 
-Add screen shots (if possible) to the app folder and link then  into this file with ![](<name>.png)

 ## Usage
 
-Describe how to use it
+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](https://banglejs.com/apps/).
