Comment on Show HN: Happy Scale – Use moving averages for accurate weight loss predictions

Comments

Whoa, this app is feature packed. It's all pretty straight forward except for this part in the beginning :

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!

Thanks for the feedback Kevin!

Oh man, can't believe that copy issue (triple-line instead of plus) has been in the first run experience for over a month and I didn't realize it... thanks for pointing it out!

Great insight about not hiding the feature list behind that button... hadn't thought about that since as a dev I know that button can never charge me w/out another prompt from Apple. Dev blindness.

Also, what an interesting (and new to me) idea about trying a conversion during onboarding. Apple would indeed allow it. Great opportunity for an A/B test.

Yes, defaulting to actual weights is something I've wrestled with. The fact is, while I knew I could play up the moving average angle with this audience, many of my customers got confused about how moving averages worked and why they were seeing weights they didn't type in on their second day of usage. Also, moving average predictions are pretty inaccurate until there's a week's worth of data, so it's really hard to have a great day 2 experience using just the moving averages. In my experience, defaulting to simple weight tracking for the numbers I display and letting power users switch to moving averages seems to have worked best.

Kevin- This is some of the most thought-provoking feedback I've gotten. You clearly put a good amount of your time into the review and the feedback, and I really appreciate how you gave actionable advice. Thanks for your help!

I think that is an error in the content, it says hit the triple line button in the upper right. Well one half of that is wrong, so if the + button did allow you to add a weight, then it meant to say plus instead of triple line.

Exactly. I changed this copy in the last build when I added HealthKit, so I'm hoping this slip up is at least limited in how long it's been there.
