My App Store numbers for the past year.

Total: $18548

The year before: $15210

And from the years before.

Some short commentary:

I mainly made the apps for fun & to solve my own problems. The fact that some earn some money is just a bonus. I also now realize that I'm very bad at predicting popularity. Some of the most popular apps are just tiny weekends projects I made thinking they would not go anywhere while some apps I put a lot of effort into failed (Today, Favorites Widget, and Recordia), and I have no idea why. My goal this year is...

...to become better at marketing. I have not marketed the apps at all other than launching them on Twitter and Reddit.

I'm happy to answer any questions.

@sindresorhus I'm more and more convinced that to make it as an indie solo developer, the develop-small-apps-and-see-what-sticks approach to product development is far better than building something big and trying to get it to market. I spent a year (on/off while consulting) building an online course, and the web app I built for automated transcriptions in a week is arguably more popular already. :D
