The app is really good. It does its job and is very detailed. It tracks trends in your weight, progress, stats, and all kinds of goodies. I would definitely recommend if you're looking for a simple easy way to track your weight. It exceeded my expectations in all the details it provides.I have one complaint though. It's called weight diary, not weight loss diary. Not everyone using the app is trying to lose weight. While the app is still fully functional if you're trying to gain weight (the goal calculator for example will say how many capries you should add to gain a certain amount per week), but even though my goal weight is over 20 pounds higher than my current weight, all of my weight gain progress is shown in red as if I'm working against my goal. The indicators, arrows, trend numbers should all be in green if your weight is getting closer to your target weight, whether that be by you gaining or losing. I'm left confused looking at red numbers when I'm making good progress and gaining weight and moving towards my target weight. This is a small complaint, and if it's fixed I'll remove this part of the review and change to 5 star rating.
