Apptimize has many great functions including a reliable visual testing tool and a powerful programmatic editor with which you can build many testing driven product decisions.

I like the responsiveness and the quality of support. Questions are addressed in timely manner, and the Apptimize team genuinely want to see us to realize the benefits of A/B testing. The service team actually performed tests for us to show what kind of benefit we could be seeing.

When it works it "just" works with minimal work from dev side
