ALERT: THIS IS A VERY DUMB QUESTION LOL
Look on the upper right side where it says MY OH, click there and then go down to the option that says "Health Tracker".
Once you are the Health Tracker screen look to the right and you will see "Tickers and Widgets".
Click it and then choose the option that says "Create new ticker".
That should allow you to design what you want and you can then add it to your signature.
