Free (with ads) or paid apps
I assume most people have seen the study from a couple months ago about mobile ads. Research has shown that while ad supported apps are usually free, you can’t get away from basic economics. The ads themselves have been shown to severely impact battery usage and cause the phone to run out of battery much sooner. While, I don’t want to force people to pay for data if they don’t wish to, I do want to give people who value battery life an option. Well, actually two options.
Second the iPhone free app has an in-app purchase to allow you to remove ads. Don’t worry Android folks, I’m working on the in-app purchase for Android devices as well.
So, it’s up to you now. Free app or longer battery life. It’s yours to choose.
