    Hi I am after a very simple mobile app to be made in Cocos2d-x. Experience with this API is a must, and responders must show previous Cocos2d-x work as a sample. This app is intended to be released immediately on the iPad (mini and retina), and Android as a later project.The app will be for an interactive book series, with simple tweening actions of images / panels. Touch interaction will be used to progress panel animation, page turning, and in-panel effects. All artwork, sound and music will be supplied (including retina images as well as normal dpi). The app will have support for In-App Purchasing to unlock future series books / episodes.The requirements are very simple and listed below;- The app will have 4 screens (Title Screen, Settings, Episodes, Episode 1).- The app will be written to parse a .plist XML file which describes in text form the animations of each panel on each page of the episode.- All Cocos2d-x Actions need to be supported in the .plist parser (move, rotate, scale, easing operations etc)- In the files section are sample screen mockups and a sample .plist XML file which describes a dummy book with 4 pages consisting of 2 panels per page.- The project needs to deliver workable source code for the iOS simulator in the latest Xcode (at the time of writing is 4.6.3).If you have any questions to assist in your bid, please dont hesitate to contact myself. Thank you for your interest.

    We own an Internet radio station with iPhone and Android apps. We also have a website streaming player. We are looking for someone to duplicate both apps and the streaming player on our website to use on a NEW station we are about to debut. The only change would be the &quot;look/color/logo&quot;s&quot; of the stations are different and would need to be changed. We have the coding for all of this from our current station. When finished we would like to have the NEW stations code for both apps sent to us so that we own them and can make changes if needed in the future. Any questions please ask.

You should be able to type in banana then type into the program the amount of bananas you have eaten and the program would keep track of the amount of bananas you have eaten as well as the amount of bananas you have in your house. So basically what the program would do is allow you to say what you have eaten then track what you have eaten and how much more food you have in your house.
