      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.

      Web Development Review from Anders Östlund

      CleverCrew is great to work with. I have known the company for four years now and worked together for a year and a half. My favorite is that you can tell them to fix anything, and they will. Not these closed boxes with specialities that have become common among certain developers but instead open minds and a "fix-it, and make it work" attitude.

      Mobile App Development Review from Brigitte Granger

      CleverCrew was recommended to me by a fellow entrepreneur, and I'm so glad I took their advice. Over the course of building my startup, I worked with at least 10 other developers and agencies, but none came close to the professionalism, experience, skill, and friendliness that CleverCrew brought to the table.The lead developer Tonya was outstanding. She balanced understanding our needs with offering thoughtful recommendations to improve the project. Her communication was excellent, and despite major time zone differences, she ensured we were always aligned and informed at every stage. She also demonstrated strong leadership, managing her team with precision and proactively addressing any issues or questions.We ultimately had to make the difficult decision to shut down company. However, having CleverCrew by our side during this challenging time made the process far less painful. Tonya's support and guidance throughout the closure were invaluable, ensuring everything was wrapped up professionally and efficiently.For anyone looking for a reliable, skilled, and collaborative software development partner - especially a bootstrapped startup - I couldn't recommend CleverCrew more. They set the bar for what a development team should be, and I'm grateful for their role in both building and gracefully guiding me through the closure of our mobile app project. I look forward to working with them again in the future!

      Si Muddell's Review Sourced from Google

      Fantastically positive and driven team who on every interaction you just know care deeply about a) what they do b) what they deliver and c) ultimately the experience the end user will have.Hugely impressed with their personal, creative and energy driven approach at the pitch stage, I commissioned 3SC to help us better scope an app. Their task was to take an in-house developed app prototype, and turn it into a fully fledged technical specification with user stories, MoSCoW prioritisation, costs, and an updated look and feel; all done with audience need at the heart.Myself and the wider team have nothing but very good things to say about 3SC. When reflecting on an agency to work with, loads say they can do it, some can actually do what they say they can do, even less do it in the spirit of real partnership and mutually respect/drive. 3SC do all of these excellently. I highly recommend them.
