With mobile app testing, you can deploy deep segmentation to bucket and categorize your users and target them distinguishably. The segmentation can be based on geographic, behavioral, demographic, or technographic factors, to name a few. You can then target each user segment separately (based on their characteristics) with a specific variation of your app experience and even control the percentage of a user segment that will be presented with a particular variation of an A/B test. This will help you understand your audience closely, experiment at a granular level, and deliver better, more relevant experiences
