As developers, it is our responsibility to understand the goals and needs of our applications, and to resist the urge to over-engineer and prematurely optimize our solutions. http://nshipster.com/nscoding/
It was pleasant surprise today to see that apps I have written as TinyShinyApps have been downloaded 30,000 times.
PictoBento was done as a showcase app and shows beautiful images from Instagram and Dribbble. It was written in iOS4 and is ripe for makeover to take advantage of new views introduced in iOS5 and iOS6 and that will probably not happen until iOS7 lands.
TV Soap Quiz was an experiment with template apps and iAds and AdMob. Even with 15K downloads, the ad revenue is minimal. Although it has easily covered the cost of the template project and additional content costs. Regular updates would help increase revenue and building up a regular release of questions could prove worthwhile.
Surely with a few tweaks, these apps can hit 100K downloads.
