    I have an existing iPad app that shares pictures via Facebook and email, and I need to make a new version that shares videos instead of photos. You can download the current version from the App Store, its called BoofShare.To test, after installing click Settings, then click "Add Test Pictures".We"ll be making a new version of the app for private distribution, not through the App Store. The new version will only share videos, not photos.The videos are small in filesize, about 10 megs each.Here"s a list of changes to each screen. Gallery Screen (the screen that shows the pictures in BoofShare)- see attached gallery.jpg for a sketch of what this should look like- make each video thumbnail larger, as in the sketch- gallery-bg.jpg should be the background imagePlayback Screen- this is what the user sees when they click a video.- see attached playback.jpg for a sketch of what this screen should look like- you can see the current version of this screen when you click a picture in BoofShare.- note that we"ll be removing all the buttons from the top, replacing them with the buttons in playback.jpg- we"ll have a hidden button to access the Settings at the top left. So touching the top left 50x50 pixels will go to Settings, just like the Settings icon does now.- user can share to Facebook, Email, and YouTube- note that YouTube sharing isn"t currently in the app, so we need to add that (see below)Facebook Sharing- we"ll be keeping the current method of Facebook uploading, except we"ll be uploading a video instead of a photo.Email Sharing- currently in Settings there"s an option to use a custom email client. Note that we won"t be using that, and instead will be using the iPad"s built in email client. YouTube Sharing- YouTube sharing is the only sharing method that we need to build from scratch, since its not currently possible in the app.- when the user clicks "Share on YouTube", they"ll be prompted to log into their YouTube account- after authentication, it uploads their video- it then automatically logs them out of YouTubeLoading Videos Onto the Ipad- currently we load photos onto the iPad either through FTP or through Dropbox. There will be no change there, we"ll continue to use FTP and DropboxMiscellaneous- note that in Settings we can set which services to share to. If you scroll down in Settings you"ll see how to disable the other services. You can disable "Allow Twitter sharing", "Allow texting", and "Allow slideshow".- also disable "allow sending multiple pictures", since the user can never share more than one video.

    Hi,I need a good developer to build an Android app for an existing dating website which uses the dating script vldpersonals (Previous knowledge of this software is a plus, because it will allow you to work faster). I need the app to be native, which means no phonegap or similar.Basically the app will replicate the functions of the website, and data added or modified through the app will be available on the website and vice versa. This means app and website will work on the same DB.These functions on the website will not be available on the app: chat, videos, banner ads, upgrade. And I want on the app a new function not present on the website: list of mobile members by proximity, filtered by what the user is looking for.

Search for "MrCrean" at the app store to see the scale of the job. Part1: Coding the appPart2: Making the content editable by the owner. So a CMS is needed. Considering the owner is not a tech savvy person the CMS needs to be easy to operate. Down there I added a couple of screenshots of the old app for you to see what the job is like.
