      Web Design Review from Barbara Schmal

      I decided to go with Site It Now because they are in Chicago IL and I am in Florida. I wanted a website developer in the US. I checked out their website and was impressed with the information I found. I am very pleased with my website and especially pleased with how they communicate with their customers. A real phone call, text, email all day every day until the project was completed.

      Really solid team. We had a messy vision for a mobile game and Trifleck helped turn it into a finished game end to end. Beta phase was not painful (which is rare lol) and they kept refining stuff till it felt right. It hit the stores and somehow people liked it so we will take that. Would work with them again for sure.

      I worked with Apptonic to develop my app, and it was a positive experience overall. The team was friendly and easy to talk to, and they helped shape my idea into something better. There were a few delays, and I had to follow up a couple of times, but they always responded quickly and fixed any issues. In the end, the app turned out great and worked as I wanted. They did a good job, and I’d recommend them with a little patience for timelines.
