UX/UI Design

Through UX design, we focus on creating a seamless and meaningful user experience by understanding user needs, conducting research, and designing intuitive interfaces, while UI design focuses on the visual, interactive elements of a product to create aesthetically-pleasing interfaces. Both UX & UI design are a crucial part of the app development process and user experience, so we make it our aim to ensure your app is a cut above the rest.


App interactive prototyping is an essential part of your app development journey. Interactive prototypes simulate how a product will work and allows us to mimic use of the app. A mobile app prototype shows us how real users interact with a product, therefore creating room for adjustments where needed. We align your prototype to your business goals, target consumer and overall design to produce an all-encompassing app experience.

Front-end development is a style of computer programming that focuses on the coding and creation of elements of an app that will then be seen by the user – development is about making sure the visual aspects of an app are functional. Additionally, back-end development focuses on the side of the app users can’t see such as databases and coding. We’re experts in both areas and we’re here to make sure the end result is exactly what you’re looking for.

User Testing

Mobile App Usability testing refers to evaluating a mobile app by testing it with actual users. It gives an idea of how easy it is to maneuver through the mobile application and learn how it can better support a brand’s key marketing objectives. You can detect problems as well as discover opportunities with usability testing and ensure your app is ready for launch. At WeAgile, we understand the importance of the user testing process, so we aim to make it as efficient and enjoyable for you as possible so you can really see your app come to life.
