About a month and a half ago, I decided to make Dark Hacker News a paid app at $1.99. I felt at this point it had enough features and I've never had a paid app on the app store so I decided to just go for it!
In the first month and a half as a paid app, its been able to generate $42 in sales! I've never made money off of an app I've built so its been awesome to see those sales come in.
At one point in June I even made it to #7 on the list of top paid news apps!!! (I'm not exactly sure how the app store algorithm works, but hey I'll take it) Up to this point I really haven't done any marketing so I'm considering getting the word out there to see how it would impact sales.
All in all, it's been awesome to make my first real dollars as an Indie Developer!
