Why would I click on the hamburger menu icon to add a weight? Seems like I should hit the + button on the top right? In fact, it seems incorrect since it did what I expected, which was slide out the navigation. The + button, did ask me to add weight.
One thing I wanted (and maybe you have it?) was the ability to set a regular notification to remind me to weigh myself. Also, for the deluxe edition what are the other features besides removing the ads? I couldn't find what those would be. It showed up a nice list of them when I hit the button, but know that most people are going to be hesitant to do so. I'm not sure if Apple would allow it, but if you could integrate the question to upgrade into your onboard slideshow, I'd bet you'd get higher conversion. The way it is, it's pretty buried in there and this is the kind of app that people won't upgrade until they have several days worth of data to see if it's worth it. Chances are your app is going to tell them that they're bad at losing weight. They're going to be the most motivated and hopeful right when they downloaded it. Hope is a good place for conversion in my opinion.
Also, for the My Weight Goals, I didn't understand why it defaulted to Track Using : Actual Weights. Isn't the point to have it track using Moving Avg Weights? I just wasn't sure why you defaulted to this.
Thanks for sharing!
