Update to current app
Working with this team was a genuine pleasure. Getting an MVP live was no small thing, and they made it happen. They brought real effort, patience, and technical skill to the project from start to finish. I’m closing the contract as my product moves into its next phase that’s entirely on where Checkin is heading, not the quality of their work. I’d have no hesitation recommending them. Any project would be in good hands.

Smart TV Player App Development for Samsung, LG, Android TV, iOS, and Web Browser
I had a very disappointing experience working on this project. The freelancer was not responsible and did not complete the agreed deliverables. Communication was poor, and despite repeated requests for updates and meetings to review the progress, I did not receive a functional application. In the end, he ended the contract without delivering the project. Unfortunately, this shows a lack of professionalism and responsibility.
