      Cross-Platform Review from Mark Gratiot

      In addition to building out a native remote inspection app for iPads, Zco concurrently ported the software to a Xamarin platform for Windows users. Zco has released nine major iterations of the iPad app, each available in the App Store, as well as the initial version of the cross-platform Xamarin build. Their nimble team boasts a wide breadth of skills to match any given situation. Having clear documentation upfront has reduced onboarding time.

      Mobile App Development Review from Katie Matter

      Zco Corporation provided full-stack mobile app development to an educational resource retail organization. They worked in Unity to build a cross-platform resource for users to advance through various curricula. The app has successfully been moved into preproduction and the second phase of development, completely satisfying project stakeholders with the quality of both its designs and functionality. The Zco Corporation team is highly creative and collaborative throughout their work.

      Startup Review from J. Michael Webb

      J. Michael Webb from CheckMySpot chose Zco Corporation for app development due to its expertise. Zco adeptly developed a hybrid mobile teledermatology platform and an admin website, demonstrating excellent communication, responsiveness, and innovation. Despite the project's evolving and innovative nature, Zco seamlessly integrated Webb's intent and met all challenges, leaving him with no suggestions for improvement. (Verified via email/call)

      Software Development Review from Martin Macmillan

      Codebludev was able to take our vision and help us deliver an app that empowers retail shareholders to make their voices heard. Theyve brought a depth and breadth of technical expertise and user experience design to challenge us on our assumptions on how people would want to interact with the app. From a mobile development perspective, we wanted to go to market with both an Android and an iPhone simultaneously.
