The Global Key is a lifestyle brand that tests imagination and unlocks boundaries. Locations in the app meet the highest standards. All spots and locations included in the app are verified, but if the user wants to view all the locations, a subscription is necessary. Before we developed the iOS mobile application for this project, we team received a version of this application that was written using Fuse technology. Due to difficulties in implementing the In-App purchase option in the Fuse project, decision-makers realized that the app has to be written in Swift programming language. To develop the UI, we used the Texture library, which turned out great when it came to developing animations. During the development especially interesting were the animations, but as one of the most challenging features we would point out the In-App purchase because of the way it is tested in the Sandbox environment.
