    An existing IOS application requires the development of an additional screen. The screen consists of a simple game that displays images and text content items on a roulette. The scope for the FreeLancer project is for the development of this screen, the base XCode project including a blank placeholder screen will be provided to the developer in advance.The developer will open the existing XCode project and implement the screen as described below. All images and sounds required to implement the screen will be provided in advance.Screen Description The roulette screen is a simple game that requires user interaction and animation of the roulette images. The roulette screen will consist of the following sections:1.Navigation bar sectiona.Back button – pops the navigation view controller to the previous screenb.Title - Textc.Play button – Initiates the auto-play sequence described below, turns into progress icon when playing.2.Roulette Sectiona.The roulette section – displays roulette items made up of a background image, content image, content text and overlay image. The content image will need to be made to fit into the bounds of the background image (see attachment) as the image dimensions will be wider than the background image.b.The user is able to slide the roulette left or right, following the user’s touchc.The roulette will provide a natural ‘momentum’ effect, continuing to rotate if the user swipes left and right with sufficient speed. Similar to how an actual roulette would move.d.The roulette will always settle in the ‘resting’ position as illustrated in the images attached when the user is not interacting with it.e.All roulette section animations must be fluid, simulating the movement of a physical roulette.f.A subtle sound will be played as each roulette item animates past the screen. This sound will be provided in MP3 format to the developer.g.If the category selection filter means there are no roulette items available for display, the ‘Please Select a Category’ message will be displayed as per the image attached.3.Categories Toolbar sectiona.The toolbar at the bottom of the screen is used to filter the roulette items available in the roulette. b.The user selects and unselects the four categories in the toolbar, adding or removing available roulette items by enabling/disabling items based on the category selection.c.All categories will be selected when the screen is first displayedd.The screen will remembers the selected categories. If the user leaves the screen and returns back to the roulette game, the state of the categories selections will be as it was when the user left the screen.e.If the user unselects a category, and the items currently displayed in the Roulette section are no longer available as a result of the new category filter, the roulette section will animate so that valid roulette items are displayed on screen.f.At least one category must be selected, if the user attempts to unselect all categories, the last attempt to unselect a category will be ignored.

    I would like to build an app very similar to this one The app needs to have membership log in area that can be leveled (eg Gold level, Bronze level). It will also need &quot;near me&quot; location services, categories for vouchers/offers, check in on Facebook, push notifications, calendar of events, a visible digital membership card to show at a point of sale, vouchers on the app need to be redeemable so they can&quot;t be used more than allocated (eg at the counter, the customer clicks on redeem voucher and then confirms in front of a staff member to claim discount, this would either remove the voucher or stamp it redeemed). App/membership will need to sync with website/online database when built.

    Need a developer for a very simple app to be deployed on iPhone/Android devices. Limited budget, not looking for a masterpiece, just a functional app.The functional components will be:First Screen:1) Email address: User will enter their email address2) Text entry - the User will be able to enter text, copy/paste into text field and preferably save text within the app3) Document attachment - User able to select document from device to attachSecond Screen:2) List of Recipients - the User will receive a list of Recipients which are included in the app. Each recipient will have an image/name and multiple recipients can be selected.Third Screen:1) Email - combines the text and documents from screen one as an email, sent from the User&quot;s email address to email addresses associated with recipients in screen two (each recipient from screen two will have an email address in the backend of the app, by selecting the recipient they will be added to the email)(Please note: I would prefer these emails be sent via a server, not via the inbuilt email client of the device)Features:1) Weekly reminder - the app will notify the User once per week2) Import contacts - the User can import contacts from phone book and save them to recipients list (not essential, potentially in second project)3) App Settings - there will be a few basic settings for the app which will be defined by the User, including a &quot;full version&quot; which will be paid but this may come as a second project.NOTES:1) Coding will be entirely up to you. Must work on iphone & android so if native is too expensive, consider HTML5 as this functionality will be achievable in HTML52) Design will come from me, but potentially as a second project, for now it just needs to function3) Payment 50% upfront, 50% once the app is released in either App Store or Google PlayI am putting together a brief and will be happy to discuss questions with bidders so they can bid a fair price.
