Hello there, I am seeking a software developer that can help me turn an idea for a simple game into a reality. I essentially need an app that gives users ONE "challenge" every morning via local notification, at a time that they set the first time they open the app. I then need that notification to lead to a short page describing that challenge. At the end of the day, the app then needs to ask if the user completed the challenge. If they have, they can advance to the next challenge, otherwise, they can choose to repeat or just skip ahead. The app would then go down its "list of challenges" to the next challenge the user has not completed, and give that challenge to the user the following day at the following time for a total of 10 weeks. The user also needs to be able to see an index (Archive) of all the challenges and be able to navigate to their explanations even after they've completed them, at their own convenience. The UI need be very simple, with minimalist design. I would love...

We need help developing an iPad app. We've started the process and have all the design elements created. We've got most everything laid out in Invision - providing a walk through for the various pages etc. We're looking for someone that has a lot of experience in iOS app development. We're also needing the new developer (you) to communicate with our current developer to take over where he's left off on the project. This iPad app also correlates with a web app - they both use the same database for storing information (Amazon Cloud). Before getting started, we'd like to discuss an estimated # of hours required to complete the app - hourly/fixed.

We have an existing MP3 player hardware, on the next version we're also building an accompanying app that would connect to it through Bluetooth and display content of it's screens along with control buttons. Sound would still be generated on the physical device, we just need to build a remote control app. The problem is the screen on the mp3 player is small and hard to see from a distance. The user is standing on a stage and the player is connected to a sound system off the stage. The solution is their tablet or phone showing a larger, closer screen via this app. If I later want to expand the apps to do more ... such as transferring downloaded music files to the mp3 player would you be able to add those features later? I have gone through the requirement and I clearly understood all your requirement Also the feature for transferring files from app to mp3 player is also possible. Let me clear about your thoughts and then we will move further on your interesting project. 1. Will...
