      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.

      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.

      Brandon Johnson's Review Sourced from Google

      I've worked with many different programs and services to create and maintain web sites since my first HTML site in the late 90s. An everchanging thing, it was difficult to keep up with all the new technologies. Web sites became my least favorite aspect of marketing because everything became so tedious. Linking up with Ruby Shore was the best decision I could have made. When I explained to them my disdain for Wordpress, they happily introduced me to their new system, Waves. Whoa. Surf's up, internetters! Waves is where it's at. I finally was able to create a site exactly the way I imagined it. I didn't run into any of the problems that frustrated me in years past using other services, and it didn't take me long before I was humming along to realize my vision. I want a thing. I get the thing. It just works. I have yet to find any limitations holding me back. Everybody Glows lives online as dreamt because of the team at Ruby Shore. Thank y'all for your awesomeness! Brando

      The business world today has become much more demanding for those of us that want to contribute. For those of us willing to put forth the extra effort, TIME has become our major enemy. Ruby Shore has not only developed applications that save us a tremendous amount of time, they have the ability to understand our process with little explanation. This saves even more TIME!!! Not to mention the flawless operation of these applications and the ability to add more features as we begin to understand all of what Ruby Shore can do for our specialized construction business. We will continue to search for ways to improve our business through specialized applications and we will continue to use Ruby Shore for those application designs, development, and management.
