Another option you might consider is Google Analytics App+Web.
It is a new type of Google Analytics property which is event-based (like Amplitude and Mixpanel). In App+Web you can collect exactly the same data and in the same format as the other 2 tools mentioned.
The great things about it are:
it is free
there is a free integration with BigQuery (though you'll need to pay for BigQuery, but for most SmB's it is peanuts - $5-30 a month)
Not so great:
reporting side is pretty buggy (App+Web is very new).
So if you are ok building your reporting in something like Google Data Studio, App+Web will be a great option. Your data analyst will especially be happy to have all the data in SQL format (BigQuery).
If you choose App+Web, then you can use Google Optimize (also free) as an A/B testing solution.
Google Analytics lets you measure your advertising ROI as well as track your Flash, video, and social networking sites and applications.

Amplitude provides scalable mobile analytics that helps companies leverage data to create explosive user growth. Anyone in the company can use Amplitude to pinpoint the most valuable behavioral patterns within hours.
