We are involved in the open source software movement as well. Because we have invested heavily in the Apache Cordova or Adobe Phonegap technology, we have developed a number of tools to help get our job done faster, save you money and produce a higher quality output.
When publishing just an Andoid and iOS app, you need to generate over 64 images for the splash screen and icons. This is to accomodate all of the different screen sizes out there including phones and tablets. You can imagine how much time it would take if you change the logo to generate 64 images again - and thats where our software comes in.
The Cordova Media Generator is one of the most popular tools and we have released it the community.
Rough Cost: $2500
