Duolingo recently published an app update for its community of language learners, forcing users to do their lessons in a specific order instead of letting them maneuver around. Sometimes it's good to offer choice and sometimes it's not. But when you've been successful offering choice for so long, it does feel like a strange move to take it away. As you can see from the chart, negative reviews spiked. These are not ratings, but rather written reviews that Apptopia Review Intelligence uses natural language processing to label as negative. Before the update, about 13.7% of all user reviews were labeled as negative, that spiked to 42.5% just a few days after the update. Also using Review Intel, I checked most used keywords since the update. Within the top 10 were "update", "new update", "layout", "new layout", "format", "new version", and "streak". All of these keywords were associated with a negative Impact Score from Apptopia, effecting the Overall Sentiment of users of the app. Duolingo should ask itself, what is my customer's love language?
