Yesterday Pedometer++ had its one millionth download. Here is the story of how it got there.
I use Pedometer++ every day to check my step count. You can get the same data in the Health app (and Activity app if you're a Watch owner), but I find Pedometer++ to be a much lighter and more pleasurable experience and that keeps me coming back. It's great to read the story behind the app.
