An experimental, scientific approach is the foundation of the Lean method.
Experimentation and split testing are fundamental tools in every developer's toolkit, but running tests in the marketplace can be tricky and messy. The techniques covered in this chapter can help you circumvent real-world limitations and obstacles, improve learning, and accelerate growth. The examples provided can give you ideas on how to run your own experiments in either the App Store or in Google Play.
With the right tools, the right techniques, and a creative approach to testing, you can continue to learn and experiment, even after you have launched your product in an app marketplace.
Now it is time to look at how we can use split tests to find out what works best in our apps as we seek to create apps that our customers will love.
