In the next update to StepTracker, you will have the ability to display distance travelled as well as number of steps. Also, background updates will be enabled with a badge on the app icon showing the number of steps you have taken. With background updates turned on, this badge will update even if you don't open the app! You will have the option of displaying either a daily goal which you can set, or the number of steps on the badge.

Also there will be an in-app purchase to disable the ads.

I expect his update to be out by Saturday at the latest!
