I like this idea a lot. * Can I export data to e.g. google maps, if I want to? * Can I annotate places I've been? * Is info automatically shared between my devices? In short, what can the app do? The blurb says "keeping GPS open can dramatically shorten battery life". Does that mean this app will do that? The (iOS) app says "designed for iPad". Will it work equally well on a phone?
