Pi Vote:Eu Brexit UK referendum poll app for iPhone and iPad

Before any elections or referendum people are bombarded with opinion polls conducted on few hundred people. Have you ever thought, where is my opinion?
This is your chance to express it.
Everyone can vote now before real referendum and let our politicians know what you think before hand.
In the process if you change your mind, so what, you can change your vote too.
All the votes collected in this app are displayed in pie chart(thats where the name comes from).
Not only that every time you launch the app, it takes snap shot of opinion for that moment and stores it for you to display in line graph. We chose to call it "Trend".
