I was rereading my last post, and realized that I omitted one more potential way to monetize self-tracking apps: distributing them among health and fitness practitioners. The idea of prescribed apps has been entertained by medical professionals for a while now. Think doctors that prescribe an app along with the pills; patient then uses the app to track symptoms before and during the treatment. Think personal fitness trainers that offer the app to their clients so they could track their progress in losing weight or gaining muscles. The app in this case is a tool that will provide an objective unbiased feedback to both sides. What do you think?
