The easiest way to convince people about the uses of bitcoin is to demonstrate it.
If you could give them an opportunity to send and receive some, without risk, that's a huge advantage.

So how about an app that simulates a bitcoin wallet? Some suggestions:
- App would start up with say 50 imaginary bitcoins which can be sent to and received from demonstrator and learner.
- They can easily reset amounts and even choose their own amounts
- Send and receiving would take around same time as actual coins
- Would have QR codes and typed-in wallet addresses
- App would have QR codes pointing to where it could be installeded for new users. This way people that learned about it can in turn easily show others.
- Could have an info page where additional tips about the currency are explained in simple terms
- App would need as few permissions as possible, as people are already avoidant of risks
- Probably should have an attention grabbing "This is only a demonstration!" label somewhere, just in case.

So that's it, a demonstration only wallet. Give newbies a chance to send and receive fake bitcoins without actually risking anything.
