    We are looking for a developer to build an iphone application, which will then need to be converted for an android device. The app is being designed to act like our website (written in php).You will first need to build a web API to communicate the Wordpress Database to the app.A user can download the app, and then be presented with a homescreen with various menus. The site is designed so that once a user logins in, they can register any tools they buy from us using unique serials which are engraved onto the tools. The serial numbers are contained on our web database, so the app will need to make sure the serial is valid, and then mark it as being used on the database.For each tool, different videos and technical information is available. As soon as a tool is registered, the user will have access to that tool&quot;s videos and information, but they will not have access to any other tools information unless they buy the tool and register the serial number.If the user wants to purchase a new tool, they will be given a list of their closest distributors which are in our database. This is determined by the IP address of the user. This is the same if they want to attend a training course.If the user does not have any internet signal, there should be a database dump so that the user can still access the information from the tools they have already registered.We have created a wireframe which goes through the app in detail, and everything it should do. This is attached.

    Iphone app that displays table of data sourced from a webserviceWe have a detailed spec for this app, which will only be shared with the winning freelancer. All copyright and IP ownership and all rights, including all source code, will rest with us and by accepting the project, the freelancer agrees to transfer all such rights, ownership, etc.. to us &quot;the employer&quot; - including an future work derived from the development. The app is visually quite simple. It consists of just 3 screens. Main, Settings, and About. There are 3 buttons (icons not words), one for each of these screens at the bottom of each screen. Details on the About screen will be supplied during the development. The Settings screen will contain the following data: Web Settings: authtoken: U0Ss3jxxxxxxxA6fEnVB subdomain: xyz Port: 5000hostname : : fred:12345Disable Auto Sleep:On/Off (default = on) Auto Connect:On/Off (default = on) Snapshot Minutes:nnn (default = 60) The main screen will be data sourced from 2 SQLite tables that the app will maintain PLUS extra data that will come from a webservice, and then be added to the SQLite table. The layout of the main screen is a table that I have attached a description called: c-too.jpgImportant: The cell that is shown as red in the attached file, is user selectable which cell. The contents of the selected cell are to be used to update the badge.. so that number is displayed on the iphone desktop as a red number on the icon. Note - user selectable. The most important and difficult part of this project will be to port some parts of the ngrok client that provides the tunnel to the webservice. i.e. a webhook. Open source code is available for Mac OSX and other platforms.. This app does not require to make a ngrok client for IOS. Only some parts of that program are needed. For example: This app is *NOT* required to provide a web interface or forward traffic to another port.. like ngrok client does. The parts of the ngrok client that are required are only: to establish the connection, keep it open, and when data comes in.. store in in SQLite file so it can be used to get the table on &quot;main&quot; page dynamically updated. See: and for details.

    The general idea is that its an app that allows a person to simulate NBA free agency. Kinda similar to free agency in dynasty mode of an NBA 2K game. What separates the app from 2K is that its obviously mobile and also I want to add in features like the stretch provision (allows a team to waive a player and take the cap hit over a couple years by multiplying the number of years by 2 and adding 1. So for example if I am on a 1 year 9 million dollar contract then I can use the stretch provision, which would clear 6 million in cap space by waiving the player) so that people can actually create cap room for their team. I already made a lot of the wireframe using balsamic mockup so the structure is there, I just need the code. The general big things I need is somebody who can write code for sorting through players via things like (age, height, position, ect), assigning player salaries, years, options, and overall contract structures, taking those salaries and putting them on the team the user of the app wants, and coding the rules that would say whether a contract would fit or not.
