Mobile App Development
I had a vision for an Accessibility mobile app to help the disabled community (and others) be able to navigate indoor spaces with ease. The team at ZCO brought that vision to life and it was more than I could have hoped for. They were transparent every step of the way, met deadlines, and were always available to explain and answer any question I had.

I selected Zco to develop a smartphone application for ecological field work on an invasive pest. The Zco team has been great to work with. They were very professional and from day one took the time to explain the development process to me, clearly detailed the costs involved, and guided me in the content development needed for the application to function as I envisioned. Praveen and his team have always been available and responsive to my questions and request for a meeting to go over issues. They have also been quick to make adjustments and fix bugs as they occurred. I will deffiniatley use Zco again if I ever need to develop another application, and I will also definately recommend them to my colleagues.

Zco had originally reached out to me on LinkedIn in the middle of my search for a bigger development team, so it couldn’t have been more of serendipitous meeting. I’d originally worked with individual contractors prior to signing on and as much as loved the one on one attention, I needed a team to grow with my business. Turns out that I wasn’t without one on one attention with Zco, the team was attentive and took care in addressing any concerns and or our of the box ideas I throw at them. We met deadline and within ballpark of estimates - I will be back for updates!

Game DevelopmentMobile App Development
My name is Trevor Connor and I'm the Founder & CEO of the Beer Pong National Championships, a March Madness-style national collegiate Beer Pong tournament which is organized through a game tracking, stat keeping and tournament organizing app for Beer Pong. I launched the first version of my app and not only wasn't satisfied with the work the first developer did but also had a terrible customer service experience with them. So I found Zco online and explained to Kevin Morrow (account manager) and Praveen Kumar (project manager) what I wanted to do for the second version: fix bugs, add new features and improve on existing features. After sending them all of my notes and files, they put together a reasonably priced estimate which we narrowed down and agreed to after several discussions. Before development started, Praveen sent me a 50+ page PDF explaining the plan for Version 2 in great detail, which I was really impressed by and showed me that they fully understood what I was looking for. Throughout development, the team would frequently ask questions about certain items for clarification through the collaborative website Basecamp, and when I asked questions about items that I needed clarified they would respond in a prompt manner. Zco was clear about payment milestones throughout the process, which also included some out-of-scope additions towards the end. Overall, this team of talented developers was able to clean up problems, implement new ideas and make the app function better than it had before. Not only will I continue to use Zco for this app going forward but I won't hesitate to recommend them to anybody I meet in the future who has software development needs.

The people at Zco have treated me and my company as more than just a client or a customer. Their team of highly intelligent developers, project managers, and salespeople turned our dream into a practically flawless reality, and each Zco team member was genuinely just as excited as we were to accomplish this goal.
They thoroughly reviewed our project requirements and were up front with the pricing, which, given my experience with their team, has been worth every penny. Our app, the Train Co. app, creates a marketplace allowing student athletes to earn money, meaning the app had to not only abide by applicable NCAA rules, but also handle those rules flawlessly. I am proud to say that they went above and beyond on the app and accomplished this goal! Our constant emails, ideas, app changes, phone calls, etc. were immediately responded to with solutions, estimates, and excitement. I could not be happier with Zco and am blessed to have them in my corner working on our app. I consider each team member a friend.

Having worked with them for over 2 years to develop our native mobile apps, We have had an amazing experience with this offshore development team. Great quality of software delivered on-time has been the hallmark of the Zco engineering team. They are pretty precise in their cost and effort estimates. In over 2 years, there has been 0 turn over in the team and I would hire each of these engineers myself for my local engineering organization any day. They have definitely helped in making our products better and I would use them again without hesitation in all my future projects.

The experience with Zco has been everything I'd hope for and even more! When I started creating my dating app (DateSpot) with Zco I only had a basic concept for my dating app. Working with Zco, they help to bring my concept into focus, creating a competitive product. With each passing week my project evolved from ideas into a sleek and professional business app.
It is very easy to communicate with the project manager and other team members using the systems they have in place. Whenever I had a question or a last minute change, Zco always responded the same day and usually within 15 minutes. Zco really takes pride in providing an excellent product and excellent customer service.

Software DevelopmentApp Designing (UI/UX)
We've worked with multiple software engineering firms on many internal enterprise applications throughout the years. There is a major difference with ZCO Corporation, though. Their production quality is first rate, and their pricing is transparent. With other companies we've experienced poorly estimated work that ultimately results in additional costs. ZCO, on-the-other-hand, gives thorough estimates that reflect true final costs. This is a major benefit when managing large scale projects. Moreover, the quality is exceptional and allows you the confidence to rollout any project to your end-users with the assurance it'll work as expected.

App Designing (UI/UX)
Let me just start by saying if you are ready to turn your board game into an app then hands down ZCO Corporation should be your first choice.
I recently brought my board game King Toe to the world. I knew it needed to be made into an app too but I had my doubts anyone would be able to pull it off. I talked to many companies and none gave me the confidence that Randy did at ZCO Corporation. I knew whoever created the app would have a challenge ahead of them especially for the UI programming. Well ZCO pulled it off. The art design was perfect. At times I thought they were reading my mind. Everything finished just the way I imagined it would be when I created the game for the first time.
Randy was there from the beginning to end which really gave me a lot of insurance through the whole process. My game was assigned to Don as the project leader. Whatever needs or wants I had from the team he made it happen. Thumbs up to this guy. The whole team did such a wonderful job, thank you. ZCO Corporation has truly made my dream come true!

<p>The mobile application developed by them provides safety to the people riding in a cab. It basically, sends real-time updates when a person is traveling through a cab to the selected contacts. We provided them with the coding of iOS mobile application which they transformed into Android mobile app. They also added advanced functionalities in iOS as well as Android version. </p>
