Even simple tools that someone can build in their lunch break can end up being very successful. That being said, the competition in customer feedback apps is intense. Unless you bring something really novel to the table, it’s gonna be a hard grind to make money.
Of course, I agree with you 100%.
I have a few more features planned, some of which are nothing new, but which will definitely contribute to the overall value. But I'm not directly interested in the money (at least for now :D)
