Great hunt.
I think what's very useful here is tracking of weight and progress as well as tracking water intake because just like me who is trying to lose a little bit of weight, I really need to be watchful of what I eat and when I eat them. The feature of setting meal time reminders is pretty awesome too as it is very unique and very useful because when you are on a diet, sometimes, you want to avoid eating but it will also be unhealthy if you do not eat regularly.
Overall, I think this will be very useful not only to those who are fitness enthusiast but for those trying and planning to become one.
