      Web Development Review from Heberto Limas-Villers

      Onix was our choice for the improvement of the company's website as part of our expansion into other states. They did a very good job of understanding my requirements and had several solutions for our needs. We had to automate a large part of the back end of the website, and they did a fabulous job with that. Communication with them was seamless, and they were very organised and diligent throughout the process. (Verified via email)

      David Dorough's Review Sourced from Google

      I read reviews of almost 100 companies and spoke with reps from 5 before finally going with Appingine for my first app. I'm sure you can pay more for less quality from a different company but why would you? They were easy to work with and quick to respond to questions. They split the charges by stage of development like every professional company should. I needed to make several changes during development and the cost was reasonable. Anthony was awesome and helped me along every step of the way. Apple has more stringent requirements than Google and Appingine was able to get the app published on both stores. Looking forward to more projects with them. Once again, don't pay more for less, go with Appingine!
