Hello, I need a quote for the development of an app for android and IOS. Note: I have no knowledge of the design I accept proposals. Requirements • It must be easy to use (It is oriented for children). • Its interface must be clean and colorful. • Responsive for Adsense. • Compatible with Playstore and App Store • Use of temporary files within Android and IOS to speed up the loading of files. For example: (When you open a game, it will download the temporary files to the mobile, when it is reloaded, it will use the temporary file to save data in the mobile, so it will have faster loading of the games and can be used offline) My page is called [login to view URL] • The activities are in html5 and JavaScript • I need to show in the apps, the categories of "Juegos Interactivos". If you are interested, read these proposals: • I do not pay in advance. • I do not release milestones without seeing the result of the work. • When you give me half the work, I pay you half the milestone. • When the work is finished, I pay you the remaining money. • If you give a quote, you can not change it later, or increase the price.
