    I know you get this request all the time and I am in now way trying to low ball this project. I studied math and many of my peer in university studied computer science and I first hand know this is a huge project. But I also know the average going rates for software development so lets play fair ball pure business/service. I need to develop a website with a monthly registration fee as well as a very small transaction fee. As you may know Vaporizers and associated items are becoming a large consumer interest. I am the founder of Vaporize-IT Distribution Corp. I have created a web or net between local (socal) wholesalers and local (socal) retailers. BUt this is growing to large for me to manage on my own. My niche is that &quot;on hand inventory&quot; is deliverable within 6 hrs and my &quot;on call inventory&quot; is available in 24 hours. We mark up the item on average (emphasis) average 35%. My on hand inventory is once the order is received is delivered by a driver within 6 hrs and my on call is delivered by a drivr within 24hrs. BUT! I want to give a retailer the option of being a wholesaler as well for certain items. If they must order some they might as well order a lot and wholesale a portion to another retailer. THey can choose to send it themselves, or have a driver of mine pick it up and deliver the item for an added cost than can be divided by both parties evenly. THe seller should be able to choose his payment option be it Cash on Delivery or Cash on Order. It is imperative that this site is exclsively for retailers (who identity should be masked with only location of store available to view to prevent retailers fueling neighboring competing stores. This exclusivity can be maintained by invite only memebership. Im willing to put up funds to have this done well for I feel it has a huge growth potential.

    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 : webservice.xyz.comhttpauth : 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: https://github.com/inconshreveable/ngrok and ngrok.com for details.

    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 www.genuinelishi.com (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.

    This mobile app will be used by staff out of the office to get a list of work/jobs they need to do, and to be able to prove they’ve done the job.I would like an Android and iPhone app built in HTML + Javascript via Phonegap, that calls to our external API so that users can get a list of their work and send back information.All the information will be supplied by our API in JSON. Data collected should be sent back to our API using JSON.Core features:- user log-in/authentication- summary list of work (time, date, title)- clicking on work shows full text details of a work- Ability to send back data from each job - arrived button (pressed once per visit to show you’ve arrived) - left button (pressed once per visit to show you’ve arrived) - take and send a photo - signature capture- messages section - user can read messages (read receipt is sent back to API) - user can reply to a message (no threads)- dynamic forms built from the API, and submission of that data back.Other considerations- should store work list and details off line, so can be viewed without active data connection- data inputted, photos, signature should also be able to queue/send if no active data connection- if not authenticated, then should delete locally stored data- GPS location should be sent with submissions (eg arrived, left button)- Would like to consider ability to refresh data- provide source codeThe project will be split up in to deliverable milestones.A full spec, and any clarifications can be provided on request.

    Project is in final stages and requires an app developer to bring to completion.Please look at the images uploaded to get a feel for the task I&quot;m asking. From a homescreen as depicted in App_outline.png, I would like to make the images (ex, App_Image.png) queriable by the &quot;ticker&quot; (the capitalized 3-4 letter terms on App_site.png).The images themselves are hosted on a cloud server as depicted in App_site.png. In addition, the app should provide a few other services to the user such as displaying lists of &quot;tickers&quot; screened by the categories listed under the search bar on the App_Outline.png homescreen image.I have been told this project at the minimum will require a url wrapper and some code to be inserted on the host site webpages to make the image fit a mobile phone. All you the developer need to focus on is making the images queriable via the host server as well as designing the app using the outline provided as a guide. Do not worry about getting the precise data to generate category lists on the homescreen, my partner and I provide tags on the host site which you can use to generate the relevant lists. For example, links on the host server with &quot;100%&quot; will compose the list of the &quot;New Search High&quot; category.Please submit an app design to be considered for hire. If you design and develop a great app, you will be rewarded in excess of your quote.If you would prefer equity in exchange for your services, please indicate. You will be given preference.
