what i need : 1) An iOs App with push notification , an edit box and send button. 2) A windows program , with 1 edit box and 1 textfield and 1 “Send Button” works like this : When I fire up the windows program , I want to be able to enter a text and press “Send”. The iOs app which is online continuously AND can be behind a NAT (on 3G connection) or at the internal WIFI network, receive this text and shows a notification on my iPhone. The iOs app will work the same way as the windows program. Instead of notification, the windowprogram will show a popup screen with the entered text. Important. • Communication in either way needs to react within 2 seconds. The notification on iOs device need to react within 2 seconds also. • I want a direct connection between both programs without a relay server. • Multiple iOs devices can be ‘linked’ to the windows program, all iOs devices will react in similar way and simultaniously.

Hi, I'm professional developer with large experience in various areas. What you want can be done in two ways: a) windows app serves as a server to which iOS apps connect and display receive notificaitons. b) with the help of apple push notification service, iOS app do not have to be connected to windows app, when message should be sent it will be relayed through Apple notification server (windows app->apple server->iOS device). Depending on which of the approaches you prefer (first one is easier to implement) I will update my bid accordingly.

Hello, I am an expert C# programmer and I can work on this project easily. The concept will be like this: -Since you want direct connection you will require the iOS app to establish a connection with the C# app by establishing a client server connection from the iOS to Windows ( C# ). -All the communication will be sent/received in that communication channel and it will be very fast as if you are connecting to a website. I am online everyday from 8AM to 10PM. I will be available for communication on skype/email and freelancer. Although my freelancer profile is new but I have good experience. Let me know if you have any questions regarding the project. God bless!

Hi, You have to run the Windows Program as server application on a static IP. Do you have static IP, if you have then you wont need the rely server. we can build both windows server application and iOs application in short time, please contact us if you would like to see a demo or require more discussion. Thanks
