Spot the Number (children app)

We are developing a children application and would need a developer to assists with the programming. 'Spot the number’ is a simple application targeted towards children ages 3 and above. At the start of the game, user may choose the 'spot the largest' or 'spot the smallest' number option for the game. In each game, a screen will show a number or candies inside a balloon. Each game will prompt the user to tap on the smallest or the largest depending on the choice user made at the start of the game. If the user tap on the right answer, praises or compliments audio will be played. If it is wrong, the balloon will burst and the audio will prompt the user to try again. There are 3 different levels for the game. Each level consists of 10 games. User will have to complete Level 1 before they are able to proceed to the next level. Images and sounds will be provided for this application. Developer must have experience in successful application development and in particular, in app purchase functionality. You will also be required to test the application aggressively for bugs and be responsible for any updates due to programming error if required. 20% of project fees to be kept in escrow as downpayment at the commencement of project upon finalization of all details. 60% of project fees to be paid directly upon completion of project with fully functioning ipa file together with the release of the 20% down payment from escrow. 20% of project fees to be kept in escrow upon successful upload of app and released one week after the app is launched and upon resolution of any bugs Please submit your best 3 apps that you have developed for consideration.
