“We had a great experience working with them. ”
They were extremely educated, accommodating and kept to the timetable and spending plan. We discovered it was a joy working with them
“The best Partners you could discover”
It was great working with such an outperforming team. I really enjoyed working with them as they were very proactive throughout all communication and also helped me by suggesting better ideas in making my app out of the crowd. The technology team was quick to adapt any changes and they delivered it on time. I'm planning to engage them for long term maintenance now.
“We do not have a working app and Grey Chain ignored all of our feedback and concerns.”
Working with Grey Chain was the worst experience I’ve had with any team in 12 years of business. They overpromised and underdelivered, failing to meet even basic contractual expectations. 1. Lack of Communication – They ignored their promised two-week sprints and avoided key discussions. 2. Ignored Design Approvals – What they built didn’t match signed-off designs, forcing me to repeatedly correct their mistakes. 3. Terrible Execution – They built a nonsensical CMS without consulting me. Core functionalities were broken, poorly implemented, or missing. 4. Unprofessionalism – They revoked my access to the code repository for weeks and dismissed all concerns despite me being the owner of the code according to our contract. 5. Unusable Product – After paying $26,750 of a $35,000 contract, the app was riddled with issues and is being rebuilt from scratch. Grey Chain refused to take any accountability and are reckless, unprofessional, and lack integrity. Avoid them.

After a lot of research and deliberation I chose Grey Chain technologies as app developers for developing distance learning app for my Institution. I was very apprehensive in the beginning as being a doctor I had minimum technical knowledge related to this .However,in my first interaction only with the team my fears were allayed . It was a smooth ride thereafter.One of the most hard working,focussed and cooperative team I have come across till date. Very accommodating,honest and dedicated to give their best. Happy and very satisfied with the Services.Highly recommended.
“Mobile App Redesign for Humanitarian Relief Org”
Grey Chain redesigned an app (that they had built) for iOS and Android to provide a coaching and community space for aid workers who work remotely and are mobile without access to reliable internet. The redesign made the app more user friendly and accessible, gave it an updated look, and included additional content and features. Grey Chain was incredibly communicative throughout the process. They were quick to respond and able to figure out the best ways to implement our wants for the app redesign. We are already planning to hire them again to do additional development work!
