My mom is taking care of few children including my daughter. She takes a lot of pictures daily to send them to parents. It's ok when she want to send using SMS app but when she needs to do this with different app she is getting lost. One day she asked to help her with it and I showed her how can she do this. Few day later she didn't remember anything and asked for my help again. Sadly I wasn't available in that moment and I tried to explain what icon she should looking for. It wasn't easy. So I thought I could create app that could teach, users like my mom, using android and allow them to stay connected.The main purpose of app is to teach so in every entry there will be section "Show me how to...". It'll be showing step by step, what to click to achieve our goal. Whenever it'll be possible there will be section "Help me with..." which will help to achieve goal. For example with sending image it allows user to choose picture from gallery and then send to app of chose. 

All the time my mother was helping with project by providing feedback and accepting (or rejecting) user interface elements as this app has to be easy to use for not tech savvy people. That's why there are relatively big (and easy to tap) buttons with descriptive texts (not just keywords). All UI elements that matters from goal's point of view are highlighted.
