AJ Development are an app development agency, working with you to bring your ideas to life and create your own unique app to accelerate your business. We're passionate about creating innovative solutions that help our clients achieve their goals and work together with our clients to create high-performance, reliable, and visually stunning applications.

All About Us

From fitness to finance, no single app is the same and we closely work in collaboration with our clients to create your vision and tailor it to your business needs. Being a small, specialist agency, we ensure that you won't be passed from team to team and will feel supported throughout every stage in the project. 


With over 10 years development experience, we have created unique apps for some of the largest online fitness platforms and clients all around the world. With our history of making highly successful apps, in a range of different sectors, we can bring a wealth of experience and expertise to your project.

We have extensive experience in iOS development (Objective C and Swift), Android development (Java and Kotlin) and React Native development, offering tailor-made apps across all platforms. 

We'd love to hear more about your idea and help you take your business to the next level, no project too big or too small, so get in touch and let's chat!
