Update (May 2011): 1 week after launching the iPhone version of Click 'N' Colour, (which had seen the usual "honeymoon boost"); and 24 hours after employing our brand-new "
App Marketing Booster Package", the free iPhone version of Click 'N' Colour increased its daily downloads by a factor of 35 times compared to its previous day's downloads.
During the subsequent 7 days, the app was featured on the front page of the Australian iTunes App Store (and other places), and downloaded close to 30,000 times by users from around the world.
Update (May 2013): After leaving this app alone for a while, we decided to fix a few in-app purchase bugs that iOS 6 had created as well as adding advertising to the app (to help subsidise future development) and live usage tracking to help us understand the market. We also retired the iPhone version as it was not performing as expected.
