for iPhone: pinch analytics (http://www.pinchmedia.com/ http://www.pinchmedia.com/). friend formerly worked there (full disclosure, really. :P) which was the main reason for going with this choice, and I tried to be fair when taking a peek at Medialets' Medialytics (http://www.medialytics.com/ http://www.medialytics.com/), but I kept returning to pinch media - both are super simple to get started with though. either way I think those two are the big ones for iPhone..there is also admob but they're more advertising-focused than anything else. apploop was another but they went out of business fairly quickly..
