I am so glad, and so grateful that we partnered with TriState Technology. TriState has been with us from the beginning, looking at our very basic sketches and bringing all of that into a reality. The things I’ve loved best about working with TriState is that the communication has been consistent, reliable and fast.






I am Sisi from Netherland and we are very happy that we found TriState Technology LLP. They have developed our Android App, Flurry which is now online in Google Play Store. Our contact person Jay was professional, very flexible, he was also very easy to work. The development team did a very good job by completing the app, applying our questions, finding solutions that we have faced with the previous team. Even though there was the time difference, the communication was flexible. We are hoping that Android App would be a super success and will ask TriState to develop the iOS version App too.






We enjoyed working with TriState, they are very professional, respond fast and are flexible to additional querries. We will continue to work together in future projects. Thank you for the good work!"






I've been working with Tristate now for almost two years. It's been a pleasure. They've been fantastic. Their developers are strong. Project management is great, they're reliable. If anything comes up, it gets taken care of right away and I can't recommend them enough.






The team @ TriState Technology are very honest, helpful, and knowledgeable. They were familiar with the latest developer rules from Apple and Google and guided me to setup all the necessary accounts I needed for both the Apple Store, Google Play Store, and website hosting. They are very agreeable and communication was very open during the entire project. Thank you TriState!
