Android & iOS Front End Applications

Hello, My name is Cristian, and I am a startup owner, which is currently developing smart plugs. I'm sure you have heard of the term (wall sockets that can be controlled remotely). We have designed an Android and iOS backend SDK, which does all the communication to the plugs/sockets. We are interested in an app developer who can only develop the frontend part of the Android and iOS apps, and we will merge the backend and the frontend into a single app. We need simple apps, nothing uncommon or revolutionary, but having a flat design to them so that the simplicity makes them look good and not dull. We have all the ideas in mind, all the graphical resources already provided, and in need of well functioning front-end applications. I have attached a list of requirements which should let you know what vision we have for our possible collaboration. I hope they don't seem to hard. Thank you for the time, Cristian
