Experimenting with Dynamic Type on individual features in the Airbnb app resulted in a significant increase in engagement, helping move our bottom line metrics. It turns out, supporting this preference creates a consistent experience across the OS that users will notice. This usage is not skewed towards particular sizes, but evenly spread across larger and smaller than default.ģ0% of people using the app had a preferred font size that was not the default. To validate the importance of this feature, we examined the data and saw as much as 30% of people using our app had a preferred font size that was not the default. At Airbnb, we try to build an app that our entire community can use - since Dynamic Type is a critical accessibility feature, we knew supporting it would make more people able to effectively use our app, some of them probably for the first time. Since iOS 7, Dynamic Type has allowed users to choose a prefered font size for their phone.
