Before I started Kerlmax, Sharpshooter was a personal side project available as freeware. I got a lot of positive feedback about the app and a lot of feature requests as well. This encouraged me to put some more work into improving Sharpshooter so I put together a plan to start the company and release version 1.0.
Because the app was previously available for free, I sold it at a 20% discount of the regular price of $15 for the first month. Unfortunately I really don't know much affect that had on my sales. Most of my sales came in during the first two weeks and everything since then has been slow but fairly consistent, even after dropping the discount. All of this has been with almost no marketing on my part. That's going to change when I release the next minor revision. Hopefully with some press coverage sales will pick back up.
