      Software Development Review from Brandon Straza

      Mobcoder has been amazing to work with. Their communication as well as their follow through is unlike any other team we've worked with to develop our platform. They were prompt, thought for themself, and brought us their own ideas as well. They worked side by side throughout the entire process. We look forward to a continued relationship moving forward.

      Jerry Paffendorf's Review Sourced from Google

      Our team at Regrid had an amazing experience working with Gravity Jack. For us, it started with curiosity about whether our nationwide land and property dataset could be viewed and interacted with in AR. A knowledgeable friend recommended we contact GJ and I’m very glad they did. From the first exploratory conversation through project scoping and execution, the GJ team was great to work with at all levels: company leadership; project managers; and hands-on designers and engineers. They took the time to listen, understand, and get excited about our unique business and AR opportunity. More than that, they executed beautifully. A few things that stand out to me: • The weekly project meetings were always something to look forward to — progress, organization, and enthusiasm • I never felt lost in the process or timeline or budget • The collaboration, communication, and design were outstanding • There were always exciting updates we could feel and use and feedback on throughout the project • At the end of the project everything was perfectly wrapped up as a deliverable and the door felt wide open for more anytime I highly recommend working with them.

      Illinois Soybean Association's Review Sourced from Google

      Gravity Jack helped us build an amazing AR app. Their workflow is extremely thorough and they will walk you through every step of the process. They excel in many different ways, but the most valuable to us was their initial design phase. They have a core team that will help you get your best ideas on the table so that you can create the best experience possible.

      Russell “Superman” Allen's Review Sourced from Google

      Pretty boring alot of free space but think they should add a dog park there. Mine sure misses Johnson Park dog park. Huber has plenty of room to put a count in to fill dog bowls. This town has nothing but movie bowling fast food and shopping. Oh and plenty of drugs if your in to that. And you wonder why everyone is on them and drinking all the time. I want to open a pool hall back up.
