Looks interesting.
We very much think so - and it's only going to get more interesting from here on in.
I think I understand that anyone can download the app, and start earning GPS tokens for just moving around.
Correct. The app is monetised by the user needing to watch a short video message which, in turn, gives them a certain amount of time to earn GPS Tokens whilst travelling around. We return 50% of our video ad revenue back to users in the form of GPS Tokens that are bought on the open markets.
What can I do with my GPS tokens that I earn?
You can use them to create augmented reality beacons outside businesses - for example, 'Buy anything over $6 and receive 4.5 GPS Tokens - or you can use them to create scavenger hunt and geocache type games and you can also use them to pay for favours in the local community - eg, walk my dog etc...
The way we've designed the system makes GPS Tokens easy to integrate into literally any business - all you need is the phone app.
Also if I can earn tokens for free why would I buy them at the ICO
Because purchasing them in the ICO gives people a way to stock up on larger amounts of tokens, meaning that businesses and service providers can instantly start using them to create their owe augmented reality campaigns.
