If you don't know the phone app Gaspy by now, where have you been? 

Gaspy was created by four Kiwis back in 2015 as a way of documenting fuel prices in Tauranga when they felt it was getting a bit high at $1.50.  

Now thanks to fuel being the talk of the town, the app has taken off and they're closing in on 900 thousand users. 

One of the co-founders, Larry Green, joined Andrew Dickens.
