      Jim G's Review Sourced from Google

      As the owner of a commercial construction and maintenance company I have constant communication challenges…getting updates from the field, tracking materials, managing hours. It was eating up way too much time for everyone involved.We brought Epic Apps in to solve that, and they delivered on every front. They built us a custom private tablet app that our field crews use daily to order job materials, log hours, and submit job updates; and an internal website that doubles as an employee feedback hub, which has genuinely improved how we operate as a company.The whole team was professional and responsive from start to finish. If you're in the trades and looking for a development partner who actually gets your industry, Epic Apps is the real deal. I highly recommend them!Jim GagnonOwner – NorCal Construction & Maintenance Inc.

      Elizabeth Stevens's Review Sourced from Google

      After I had a false start with another developer, I found Epic Apps- they were ready to jump right in and were conscious of my budget. They made my dream come true of launching my own meditation app, Eyes Inward. Highly recommended!

      TrustFall's Review Sourced from Google

      I had an excellent experience working with this tech development company. They helped me create a unique app from scratch with creativity, collaboration, and thorough attention to detail. They truly understood my niche and provided a solid foundation I can expand on. Communication was professional and consistent throughout the process. I am very happy with the cost, service, and efficiency. The team's enthusiasm and commitment were also spot on, making the entire experience enjoyable and productive. Highly recommended! Truly, Epic!
