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)

Mobile App Development Review from Khang Pham
Choosing dotcode was one of the best decisions we made for our business. Their team's ability to understand our vision and turn it into reality was remarkable. Not only did they provide app development, but they also ensured our project was completed quickly and successfully. Their post-payment work format eliminated any risks on our end, making the collaboration seamless and stress-free. We couldn't be happier with the result

Web Development Review from Ben Goodfellow
Dotcode exceeded our expectations in every way possible. Their commitment to meeting deadlines and budgets was evident from the start, and they delivered a flawless end product. The transparency they maintained throughout the project gave us peace of mind, knowing exactly where things stood at all times. If you're looking for a reliable partner for your design and development needs, look no further than dotcode

Product Design Review from Sofia Diaz
I had an idea and vision, which intent helped me bring to life. We required a platform that would be usable on different types of mobile and desktop devices, as well as work on different browsers.We went through the process of designing the product and building an MVP. Their UX designer evaluated the mockups I gave them. Then, they gave me some suggestions on how to improve the product and provided a UI designer, who built the interfaces.From there, intent handled the following stages of product development. We went through several iterations based on user feedback for the MVP, and every feature was QA-tested before release. Now, we continue to improve the product on a monthly basis.

Web Design Review from Christopher Calarco, D.C.
Our company had an excellent experience partnering with Jeremy and the 97 Switch team on our website and SEO. The initial build was on a tight timeline that was kept, and after the sites completion we saw a significant increase in new business coming our way. More medical professionals learned about us and wanted to join our network, which was an amazing bonus of working with 97 Switch. We've committed to work with 97 Switch for the next several years given they have been crucial in guiding our plan for growth.

Web Design Review from Justyna Chrupek
We hired them to build a new website. The website was quickly completed in just a couple months, and weve seen markedly positive results from 97 Switchs efforts. It's a new marketing feature that we use on a daily basis. The improved quality has facilitated our communication and made things much easier. Weve received great feedback from our vendors, investors, and customers who want to view our properties. Internally, our staff is excited to see what's going on in our company. We are definitely proud of our new platform. Our executive team is excited to be featured on the new website; previously, they didn't even want their picture shown. Before this redesign, we were almost embarrassed to send out the link. Now, we can comfortably share it with our investors, potential investors, and landlords so they keep track of our updates on a monthly basis. We love how this site presents the face of our company.

Web Design Review from Adam Greenberg
We've seen tremendous growth and exposure. The website has generated a number of new leads and weve received tons of cold calls from potential clients. This is thanks to 97 Switchs efforts to increase our digital exposure. We communicate primarily via phone and email and theyre highly responsive. I receive a response to emails within minutes and they get back to me within half an hour if I request a phone call. They're able to conduct face-to-face interactions in order to truly understand the goals and business culture of their clients. This allowed them to create a design that accurately represented our brand. I've had nothing but positive experiences with 97 Switch and Id recommend them to anyone.
