Keyhole built a client-facing, cross-platform mobile app allowing users to view movie times, book tickets, purchase concessions, watch on-demand, track rewards, and more.

Technologies: Flutter, Xamarin, GraphQL, C#.NET, Dart

The Keyhole team worked to rewrite an original Xamarin app in Flutter for AMC Theaters. In addition to the rewrite, the team added a handful of new features including notifications and an interactive map.
