    I to convert an iPad app to Android. The app is for a co-tenancy space, and they do not have a receptionist. On entry to the office block they see an iPad that has the company logos on it. Clicking on one initiates a connection to an iPad mini in the relevant office space. They have a face to face conversation and hang up. The person in the office will then go to the lobby to pick up the visitor from reception. We have the iOS version live now. The API is all set up, and will naturally need a slight modification for Android devices. The API is built on a Wordpress backend, and our PHP developer will handle changes to that. It&quot;s all in JSON. The Video component is run by TokBox - you can see their documentation on their website. On iOS we use push notifications to alert each device of state change, to test the API, and set up the device on the appropriate office building / floor. When an update is made to the directory, a push notification is sent to update the lobby device. The final product must be able to work on Android Tablets. The Receiving device must also work on Android Phones, if required I will provide a PSD for this. You will be required to liaise with our Server side developer, and use the TestFlight platform for deployment of builds for testing. We will also provide a Git repository for the code. We will provide:- wireframes- API documentation- full photoshop files with design You can see a bit more about the project here

    Secure Lock App - The idea behind this app is to restrict access to visitors of a persons phone. The restrictions are put in place by the phone owner. By enabling the app the phone owner is able to create usage profiles based on the specific type of visitor to the phone (E.g Child, Teenager, Spouse etc.) In these profiles the phone owner can choose the enable / disable whole genres (E.g Banking, Social Networking, Settings, Phone, Messages, Mail, Games etc.) or specific application themselves. Even though these apps restricted after the profiles set the application can still be used by a passcode set by the phone owner.
