We already have a website prepare to run on iphnoe. Now we are looking for an app to work on iphone (and ipad) without using internet. The overview of the app is following: 1) Every day the app will sync with internet two specific time of a day, the specific time of the day will be configurable from the code 2) the system will create some data during the operation. During the sync session these data will be transmitted 3) during each sync session it will also check for the new db file (in csv format) and download if available. 4) If the app was not able to connect to internet for a long time when you open the app it may check in t he background if there is new files to send or receive. Or maybe in case that there is no internet the app check at every 10 minutes and when internet come back the app can check for updates every 2h or more… 5) We will create the service in house, but you can define the service. The service will exchange data in json and file 6) The app may use csv as its internal database or it can use any db technology (i am open). 7) This system has authentication and the same authentication will also need to connect to the server. Please bid with a technical overview of how do you like to implement the system. Any bid without technical overview will be ignored and deleted.

Hi there, I'm a mobile applications development team manager and a developer myself too, and I'm very interested in your job post involving these skills. We have recently worked in iOS/Android/Windows Phone apps development and we have also User Interface design and Graphics design skills too. Our team also has so much experiences in Web/server development. We have consistently delivered projects on time and under budget, which has earned us many positive ratings, as you'll see in our work history, a number of our projects are in our freelancer.com portfolio. Some of our works are very similar to your requirement. We are available to chat via freelancer.com chat tool and your suggested chat tool, and would be happy to set up a convenient time to discuss the application you're moving and some ideas about the safest way to get it into the cloud. Thanks, Quy.

Hello, I'm very interested in your project. I done with some projects that have synchronization. For technical review, I suggest the solution for each note: 1. If user open the app for each day, application will check, if it's another day, it will sync to server. 2. In sync process, the app will communication with server to get new data and upload new created data from app. 3. the same 4. The app will observer the internet event, if internet available, the sync will start immediately. 5. Please let me know the business of system, and i think I can design api with you. 6. I will use CoreData as database in the iOS app 7. There will be a form to input username and passwork or we can fix username and pass in the code. Please review my solution. If OK, we can start. Thank you.

My team is really interested in this project as it is exactly within our scope of expertise: We are web/ app design & development experts. Please kindly visit our website phamtech to learn more about us and our works similar to this type of projects. Working with a team who has both in-house DESIGNERS and PROGRAMMERS means that you can take advantage of both: Our designers could help revise the design even in coding process, which is a GREAT benefit for any ongoing project. + We plan and build. We don't use prebuilt templates which produce conflicting codes and bugs and hurt the system in the long term. + Our team is 100% in-house. We don't outsource projects elsewhere. So you pay for the real service - not marketing fee. In short, if you need an experienced team who offers *real English* communication, beautiful design & optimized code, premium after-service, in time and to budget, then we are the choice. If you need something based on solely ONE of the above criteria, then we're still happy if you decide to give another freelancer a chance. Just bookmark our website and come back in case the selected freelancer can't meet your demands. * Even if you don't go with us, avoid fast food services. Chances are they omit the software planning & testing phases for the sake of reducing time & cost, which produces unsustainable codes behind and creates more distrust in this market!
