Second tap single finger zoom

I've just starting using the new Google Maps on my iPhone and I'm loving the second tap single finger zoom. It seems so much more intuitive for a device you are supposed to be able to use with a single hand. I really prefer it to pinch to zoom (I hope google have got a patent on it!)

As I sit here patiently waiting for my Nexus4 to arrive, I was wondering, are there any other android apps that use this zoom feature?
