    THIEF! SCAM!! NEVER WORK WITH THIS MAN. (Or at least never give an upfront payment). We communicated everyday for weeks, then he sends initial designs and then I never hear from him again. He said he broke his leg (probably a lie) and then nothing. He seemed like a really nice guy, but I guess the best scammers always are. Be warned.

    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.

The app will also allow messaging among users. The developer will also build the server side of the app as well.

I also want someone that is very detailed in what they do. Developers who just know how to code and don"t know how to apply the details of the elements of the app effectively will not be a good match.

Send me samples of apps you have developed that are on the app store.

    Hi,I have bought some IP cameras from China and would like to sell them with the option for the customer to view the cameras via their mobile phone. I have tried many apps but only one seems to work using a "GID". The other apps require me to input an IP address but for some reason the other apps require an IP address and it does work.My problem with the existing software is that it seems to connect to a Chinese server, and my view on this is that it"s not safe. So I would like to get a price on how much it would cost to build a similar piece of software that would allow my customers to login and view their cameras from anywhere in the world.

    I need a mobile tracker application(spy phone) for IOSThis application must run on a Iphone with Jailbreak.I have developed this application for Android.I don"t want to change the server for the IOS application. It must connect to the same database using the same php scripts that upload data to the server. I didn"t write a complete documentation of how data is sent to the server, but I will do that when someone will take this project.Basic application logic:- The user must install the application on his phone.- The application must ask the user for an email, a password and a phone name. The email/password/phone must be transmitted to the server. Based on this the user can login into his account(the server side is already made but the application must communicate with the same php scripts).- If the application was already installed on the phone, the server will say that he knows the phone based on a unique phone id that the phone must send to the server. If the application was already installed, then only a login screen will be displayed on the phone(with the email used previously).- Once the application was installed on the phone and the account was created, the application must track the activity of the phone.- Every time a new log(sms, call log, picture..) is tracked, the phone must store that log into an internal database.- Periodically the application will try to send the unsent logs to the server. If the phone hasn"t sent new data to the server(for about one hour) and the phone opens its internet connection, the application must restart the service that sends new data to the server.Logs that must be tracked- Phone call logs with call recording(including gps position, contacts and call duration)- SMS (including gps position and contacts)- GPS logs (periodically gps logs)- System logs(restart phone, shutdown) including battery level- Contacts - track when a new contact is added into the phone- MMS (including gps position, attached picture and contacts)- Browser logs (Visited website with probably the default browser application)- Pictures(Tracks the photos taken with your phone)- Whatsapp messages(with jailbreak you should have access to the whatsapp database)- Facebook messages- Skype messages- Viber messages- Calendar -Tracks the new events in the calendar.The code for this application must be clean and well documented. It is possible that I may make changes in time.The application must be tested on a real Iphone device and on multiple IOS versions. You can focus on development and someone else can test it. I expect it to work on multiple devices and multiple IOS versions without any problem. The testing can take some time(the application must work in real live scenarios) I am interested to meet a serious and good IOS developer that I can work with in the future for upgrades or for other projects.
