      UI/UX Design Review from Jamie Flett

      Chimpare Design Lab helped us with a UI/UX research process, which included in-person interviews where they walked users through unboxing, connecting, and using the features of our smart air conditioner. From there, the team took the findings and produced a report for us to make improvements to our app and increase our activation rates. In addition to the report, Momentum Design Lab also redesigned some parts of our app using Figma.The project required a very iterative process, so we required more than one discovery call to get started. In fact, they didn't just work with me; we also integrated our consumer marketing insights team to identify participants. We also collaborated with them to figure out how to recruit the right users based on our target customer profiles.

      Mobile App Development Review from Piera Musselli

      Great service from start to finish. The team are very knowledgable, helpful and are negotiable on price which is great. I had an app development for just £400 for IOS devices and in my opinion it is some of the best design and features i have seen on any new app.

      Reez Deez's Review Sourced from Google

      Quality developers, if you're looking for development for mobile applications these are the people to go with. They are overseas but they will give you double the quality at half the price an American company will give you if you are a startup! American start up companies charge you double and outsourcevthe work to lower quality people. You will not be disappointed with these guys here. The attention to detail and your needs are superior to American companies that outsource just to make a few bucks off of you.

      I've been working with Techjays since they started and have never been disappointed. On each project I have worked with them they have always delivered on time, on budget and with great quality. They adapt to the needs of the customer and have been in large part, more of a technical co-founder for my start ups. I'll continue to work with them and highly recommend them to anyone!

      We've been working with TechJays the past 18+ months and the outsource experience has been great. They are agile and compared to previous outsource experiences, their competence, quality, and delivery punches above the rest.
