I currently have the free SparkPeople Diet and Food Tracker on my iPhone. I haven't been entirely thrilled with it, so have rarely used it. I did use it a bit yesterday, and it synched okay to my SP account.
In looking through the App Store, though, it appears this app is no longer supported, as it no longer shows up in the store. In its place is an app with the same name for $3.99. However, this app gets poor reviews, as it appears it crashes more often than not for a large number of users. It makes me wonder if I want to pay for an app that doesn't work and I might not use all that often.
It appears the app has been around for a year and was last upgraded prior to iPhone's upgrade to iOS7. Is there another upgrade in the works for this app?
