Brand Design Review from Rhys Williams
League were fantastic. They exceeded all expectations & we are super happy with the end result. Their communication, willingness to go above and beyond & dedication they put into their work really stood out. I will definitely be recommending & returning to them with any further work that I need. Great work team!
Web Design Review from Shawn G.
We went looking for a new company to re-design our website. We have been down this road before and it's impossible to figure out who's the best fit. We interviewed at least 5-10 agency company's and independent contractors. League came out on top with the best vision that we were looking for. Great work, great design, great cost. Overall, very pleased and will continue to do business and follow-up work.
Web Design Review from Andrew Rymarenko 🇺🇦
Project management was highly collaborative, prioritizing quick feedback loops and structured delivery of design milestones. While all major items were delivered on time, their exceptional responsiveness and flexibility in integrating complex creative feedback was a highlight of the process.

Mobile App Development Review from Anonymous
We partnered with Build Me App for two projects: developing clickable prototypes of our mobile application on Figma and creating a mobile application from scratch. Its team, known for high ratings and experience, delivered a prototype that accurately represented our vision. Additionally, the agency successfully designed a pitch deck that met our objectives. For the second project, Build Me App developed a mobile app from scratch, managing design, functionalities, and backend infrastructure, delivering exceptional solutions. We value the agency's expertise, dedication, and professionalism.

eCommerce Review from Mahil Jasani
We hired aPurple to build an MVP for our modest fashion e-commerce startup based in the UAE. The team at aPurple understood our vision from day one and helped us turn it into a working mobile app within just 10 weeks. Their process was structured but flexibleperfect for an early-stage startup like ours.They helped us define key features, set realistic milestones, and made sure the MVP aligned with our target audience. Communication was smooth, and their suggestions often added real value to the product.The final app had all the core features we needed to go live and test the market, and it performed well with real users. Thanks to aPurples support, weve now started onboarding suppliers and planning for scale.If you're a startup in the UAE looking to build a solid MVP with speed and quality, Id highly recommend aPurple.
