Lose It!, from FitNow, is the top choice of calorie counters, with 3.5 million downloads in the 14 months since it became available. But more noteworthy is that 190,000 people have bothered to rate the app, usually with high marks, which suggests that the software has some staying power.
Based on a week or so of playing with it, the ratings are well-earned, and probably would be just as high if it cost a few dollars or more.
