David Smith, on his app Pedometer++ hitting one million downloads on the App Store:

Pedometer++ has become one of the most important apps in my portfolio and probably the app I’m now most widely known for.

It also carries with it an attribute that I’ve never experienced with any of my other projects—a sense of doing genuine good. I have had countless reports of how it has help people get healthier, recover from injury or lose weight. These are the stories that really impact me as a developer. The thought that something I made in my basement can have extended and improved people’s lives is truly remarkable.

David’s commitment to the app through the years is equally remarkable. Pedometer++ is one of the apps that is helping me live a healthier lifestyle, and it improved so much since the original version (which we first covered here).
