I had already an app on android with ~3000 active installs for doing simple shopping look ups. I changed it to throw in some affiliate codes and fixed a crash and updated it approximately 18 months ago now and haven't made a single update.
It's next to nothing but it encouraged me to look more into at least trying things out for myself - I would never have thought (and still can't) it would be any more than a personal exercise. If I look at it as "free netflix for 2 years" then it's a real thing to me and "means something".
