I wanted to get two things from building an App<p>1) I wanted to learn how to build and deploy an app with react-native and google cloud.<p>2) Also, I recently purchased an item in a department store and gave my personal email address and I received my receipt as expected. But I also received a load of emails about promotions over the coming weeks which cluttered my inbox.<p>My App can be found here:<p><a href="https://itunes.apple.com/gb/app/recbox-io/id1378437194" rel="nofollow">https://itunes.apple.com/gb/app/recbox-io/id1378437194</a><p>and<p><a href="https://play.google.com/store/apps/details?id=com.recbox" rel="nofollow">https://play.google.com/store/apps/details?id=com.recbox</a>
