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.

Zco Corporation provided full-stack mobile app development to an educational resource retail organization.

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)
