Bird's Eye: A powerful tool for exploring App screenshots

摘要

At Duolingo, striving for excellence is one of our core operating principles. We strive for excellence in our mobile app by devoting ourselves to a high-quality experience for every learner. As part of our commitment to building for a globally diverse audience, we've dedicated our efforts across the plethora of languages, operating systems, and mobile devices that our learners use. We run hundreds of A/B tests simultaneously, and staying on top of all possible versions of the app a learner might see depending on their user interface (UI) language, course, and device can become overwhelming. Until last year, there was no easy way to visually compare the same learner experience across multiple languages and devices to ensure a smooth, enjoyable experience for everyone.
