In mobile applications, A/B testing, also known as split testing or bucket testing, is the practice of testing different user experiences. With A/B testing for mobile applications, AUDIENCES are split into TWO (or more) groups and a variable is tested to see how it affects user behavior. By using this, we can IDENTIFY and deliver the best possible user experience. In iOS app, it is possible to conduct A/B testing in three STEPS:   

• Step 1: CONFIGURING a test that prepares two versions of your iOS application (namely A and B) with required test metrics
• Step 2: Testing two of the above iOS versions simultaneously
• Step 3: Analyzing test results and selecting the best version to release

In the above diagram, audience/visitors are split into two groups to check two versions of the application (Variation A and Variation B). Conversion rate (% of visitors to your application who reach their desired goal out of total visitors) of variation A and B is 23% and 11% respectively. Now, you can identify which version is best and deliver the best possible user experience.
