My company, acerapps, recently did an exhaustive project looking at finding the best solution for mobile analytics for our apps – we have a dozen of them. We started looking at Mixpanel, Localytics, and Amplitutde. None of them were really to our liking and also too expensive.
We finally found Pyze, a startup that has an intelligence platform that automates a lot of the things we felt we needed to do manually with the mobile analytics solutions. Things like segmentation and campaign definition were a real pain points for us. Pyze automatically segments users across behavioral attributes and makes userbase exploration straightforward. They also have pretty good tools to automate user engagement based on behavior.
I asked them how they could offer the service for free long term and they said they will be introducing more functionality in a paid tier. Its worked out really well for us and we've deployed it in 4 of our apps. We'll be rolling it out to the others as we do the next set of updates.
