I was surprised by the amount of mobile app analytics tools out there. It's hard to pick one, even if you just need a specific feature. And although they use different terms, most support the same basic feature set.
I ended up doing a comparison table of the ones I found:
|Service||Google Analytics||Facebook Analytics for Apps||Flurry (Yahoo)||Mixpanel||Appboy||Tapstream||Localytics||Countly||Answers|
|Paid features||$150K/year for support and SLA||-||-||Tiered from $150/mo||From $100/mo (source)||$500/mo for all analytics features||Tiered from $200/mo||$125/mo for crash reports and messaging||-|

- I focused on general analytics features, like real-time information, user flow and custom events. There are more tools focused on stuff like marketing automation, app store analytics, referral tracking...
- I only included tools I could signup right away, and was able to find pricing information. No request demo or trial contact forms.
- I didn't try all the tools, so some information might be inaccurate.
There wasn't any Android-only tool. It seems once you got the analytic back-end developed, supporting another mobile platform is easy.
Do you know another tool I should add to the table? Leave a comment below, together with your feedback.
