Hi,
I recently wrote a blog post on the steps we took to market our latest app,
3D Bookshelf. You can read it
here.
3D Bookshelf made it to #79 in the top 100 Paid Apps chart in the US and was around that position for about 2 weeks. The app was also the #1 Book app in the US for the same period. We sold 16,000 copies in February.
If anyone has any questions or suggestions please feel free to post here or contact me at my blog or twitter.
