    I am looking for a iPhone developer that will be willing to make a social networking app. The main point of this app is to post and comment on posts all anonymously From posting a status anonymously, to commenting anonymously. They will be able to make a account with an email set up a username and password and be able to have a picture and biography while viewing their profile. There will be four sections on the top of the iPhone the first is feed, second is Others, third is Activity, and the fourth is Profile. The feed is all the anonymous posts of people you follow and comments. The second thing is activity which is a brief list of things people of your friends list have commented on. The activity is where one can if an anonymous person commented on their post, and also if they are private to control who follows them. and Your profile is your picture, name, and biography it, also below it ONLY shows how many posts and things you commented on, it doesn"t show any posts. When you make an account you must be following at least 10 people to view post to make it as anonymous as possible. You can make yourself private to control who follows you as well. and also to make a script or something to make it so when one posts something to their followers after it will be deleted on the main database so it will not be linked to the person who posted it anywhere. The point is to make it as anonymous as possible. The last thing is to put a small ad at the bottom of the screen while in the feed or others section. This idea is copyrighted by myself so do not try to make this without me.

    Hi,I need someone to create an iOS/Android app. The app is a very simple game project I was planning on doing myself but due to lack of time and coding knowledge I"ve decided it would be easier to get someone with an idea to help me make it. The game is about a small ghost who when clicked moves to a random location on the screen, often colliding and bouncing off the walls. There will be a point system/time mode. I would like the game to be tested and fully functional, I would also like there to be high scoring system/game center function, Facebook share button. I have a large percentage of the components such as backgrounds,character,sample of the game. I just need a proper 100% running/functional game with no problems. This is not a huge task and if anything it"s a rather small one with most of the game clearly outlined to whoever chooses it. I also have a few other smaller ideas which I will discussion.Please message me if you have any questions. Thanks for your time :)Rob

    I"m after an iOS developer who can help me create this app and support it through the review process with Apple.App will be uploaded via or developer account so must be built with specific names certs etcWould be preferably to work with someone who also has android development skills as we also need to create an Android version of the same app in phase 2 of this project.The app should load a splash screen (artwork will be provided) - fade from black to display JPEG image then fade again to black after 2 seconds. The splash screen also needs to contain a text based link. The animation needs to- fade up from black over 1 second- remain on the splash screen for 2 seconds with no animation at 100% opacity- text based link needs to be active during these 2 seconds (link should open safari and be active from text only not entire screen)- fade to black over 1 second- fade from black to web viewer over 1 secondThe app should then load a full page web viewer which will draw its content from our online site (url to be provided) - this content will need to be drawn from our servers rather than packaged as part of the application. The web viewer component will need to support SSL connection to our server and present the content in portrait and landscape orientations across iPad and IPhone devices.A black status bar menu should be visible in both landscape and portrait orientationsThe app must also handle the use case where an internet connection is not available and display a custom message- If launching the app with no internet connection, network check should be performed on splash screen and not transition to empty web viewer- If already on the web viewer and internet connection drops then the pop-up network warning message should be displayed- Each time the user attempts to click on a link on previously loaded web viewer content then the pop-up network warning message should be displayed- If the user moves the app to the background then returns to it without an internet connection, then the pop-up network warning message should be displayed

    We are looking for a professional developer to build a webbased backend application for a service provider to service their clients. The webbased application will be the operating center of the company. It will be used to communicate with the client through an iPhone app. User experience storyboard:The client has a contract with a service provider. Whenever he needs anything arranged, he can call them 24 hours a day, 7 days a week. The company has also created an iPhone app to offer chat functionality. The client really needs to get a taxi. He opens the app, enters his PIN to login, and sees the frontpage, where he can choose between ‘Live Chat Function’ or ‘Actual Status’. He selects ‘Live Chat Function’ and sees 8 buttons. He selects ‘Taxi Service’ and a chat window opens. The service representative gets notified on the backend and starts the conversation. The service representative discusses the client’s wishes and logs them into the backend. The client also sends his GPS location to the service representative so he knows exactly where the taxi should go. The chat is ended and the service representative arranges the request. After that, he logs a status update into the backend. The status update is pushed to the mobile app of the client. Whenever the status changes, the service representative will update it in the backend and the message is pushed to the app of the client.Schematics: Download attached document for more requirements
