Lose It! for iOS offers a simple and clean presentation, centered around counting calories, setting goals, and logging activity. This one isn't all that modern or cutting edge, however, it has some very nice elements to it.
Lose It! presents in portrait mode to deliver a fairly static user interface that's a bit of a mixed bag. Parts of it felt very modern and stylish, while the bulk of it was very old school, presenting minuscule text with rather plain menus. To get started, the app will ask for some basic info, like age, weight and fitness goals. From there, you can start logging your food intake, which was the portion of the app I liked most. The app uses your GPS function to locate eateries in your area and presents their full menu to streamline the diet entry process. This is great if you eat at local fast food places, but the app completely overlooks virtually every other eatery. Foods are listed by category and feature small images to help identify each one, bringing some much needed visual stimuli to this dry presentation. I loved the charts and graphs that started to populate with each new entry I made.
On the exercise side of things, the app presents various body parts you may like to focus on. Just click on any of those to bring up details and a fitness regimen. Pretty much the bulk of this area was reserved for the pro version of the app, which is moderately priced at $40 a year.
Lose It! is decent for what little it does. However, it's hard to tell from the free version if it's actually worth $40 bucks a year for the premium features. I've seen better fitness apps, so I guess I'd have to edge toward nixing the paid version.
