It would be very helpful if the calorie budget "in the zone" gauge showed how many calories you should eat or burn to get in the zone. I know this is displayed on the website dashboard, but it doesn't seem to be visible in the Android app (either in the dashboard or the full screen).
This would allow users to make a more informed decision on when to eat and how much to eat. For example, if it is lunch time and I need to eat 350 kcal to be "in the zone", I will know not to eat less then 300 or more than 400 calories worth of food. If it is 3pm and I am peckish and can consume 100 calories to be in the zone, I know a banana won't be overdoing it. And as the day progresses I would see that number change, meaning I can bank some calories for dinner in a more informed manner.
