I opened the MS Health app on my Windows phone this morning to look at my sleep tracking from last night. When I got to work, I noticed that there was a badge on my live tile with the number 4. I opened the app again, but I can't figure out what the 4 is indicating. After closing the app, the badge is still on my live tile and didn't reset like badges usually do after apps are opened. Does anyone have any idea what this badge is supposed to be telling me?
