Second the "spin" on the app -- I've logged my food/fitness every day, but I have "breaks" in my "log into Spark People" from the days I'm on the road. I log through the app on those days, but don't get "credit" for having been "logged in."!
But thanks for the mobile site link -- didn't know there was one...

Currently maintaining within 5 lbs. (+ or -) of goal. I weigh daily, but also use a tape measure and the fit of my clothes to guage how well I'm doing.
