persona analytics and realtime data hooks deployment
This is a solid tool for mobile analytics if you can afford it. The SDK was clean and simple to use and didn't cause any issues for us. The support staff is fantastic to work with. Advanced integration required a lot of work, but there wasn't anything I couldn't do in the end with all of the APIs that they have made available. Push and in-app messaging features are a little simple, but they did work on both platforms. The developer tweaks were useless to me, I really needed a feature like that too. There are other tools that I'd recommend for user engagement, but for analytics this has been my favorite.
Super simple to use, events can be created without releasing an update to your app
