Mobile app A/B testing tools allow for the creation of randomized experiments using two or more variants to compare the performance of different alternatives and determine which one works best for a mobile app. These tools can help improve a mobile app's design and conversion rates, gauge interest in new features, and measure the satisfaction of different app changes. Various mobile A/B testing platforms are available, including Optimizely, Apptimize, Leanplum, Mixpanel, Taplytics, Adobe Target, Kibo, Oracle Maxymiser, and Vanity. These platforms offer a range of features and support multiple platforms, allowing users to choose the best tool based on their needs. Many of these platforms are used by well-known companies such as Microsoft, Zendesk, Atlassian, Hotels.com, HotelTonight, Glassdoor, Delivery Hero, Tinder, Zynga, App Annie, NBC, Philips, Swisscom, Progrexion, FOX, The North Face, PANDORA, True Religion, National Geographic, and more.
