The best thing about this is that it has helped me in many ways, especially with my diet plan which I am currently doing while training for an upcoming marathon! It helps you track your daily food intake as well as calories burnt at different times of day. This app also helps you keep up to date with any changes made to your food preferences or requirements. There can be some lag time between when you make a change and see those updates reflected in the app itself. But overall, jumping fox does have great customer service so if there are problems then they will help resolve them immediately. I use this app during my long runs to figure out how much energy i need each hour. Also, using their calorie tracker feature makes meal planning easier.
