Mobile App Development Review from Eliana Lubofsky
AppMakers USA was a great experience! The team was professional, responsive, and easy to work with. They understood my ideas and helped turn them into a quality app. I'd definitely recommend AppMakers USA to anyone looking for reliable app development services.
What stood out most about working with AppMakers USA was how attentive and helpful the team was throughout the project. They listened to our feedback, kept us updated and were always available when we had questions. Everything was handled professionally and we felt confident that our project was in good hands. Were very pleased with the final outcome!

Startup Review from Roei Schneider
I work in IT support, so I was probably more interested in whether this would save us headaches than whether it looked impressive. AppMakers spent time understanding why tickets were getting stuck and found that a lot of our delays were actually caused by people not knowing who was supposed to do the next step. That was a very simple observation, but we had never really stepped back and looked at it that way. The system they planned would make ownership much clearer and let employees see what is happening without constantly asking us for updates. I liked working with them and would do it again.

Katherine's Review Sourced from Google
What impressed me most about this company was how genuinely invested they were in bringing our vision to life. They truly cared about getting it right and shared in the excitement every step of the way. Their passion for what they do is obvious, and it made the whole process not just productive, but fun. It felt like they were part of our team, not just a vendor.

Black Flag carried us from concept to production on a very complex website with multiple interest holders. Designing a website for the California Department of Education means that we serve a varied user base and must adhere to the highest accessibility standards. Black Flag took input from internal teams, educators, and other interested parties that would be accessing and using the site. They adapted their designs to meet the needs of various types of users, coming up with not only attractive design elements, but created code that added automation to eliminate some of the manual updates. Black Flag provided us with a high-quality product and were so much fun to work with along the way. A helpful tip: save some of your funding for ongoing maintenance because once you start working with them, you won’t want to stop!

Rob Bowman's Review Sourced from Google
The team a Black Flag Creative interviewed our group at key milestones throughout the web design process to thoroughly understand our industry and the goals we want to achieve with our new website. I've been through a number of website updates with just as many web designers and Black Flag communicated with us in terms the layperson can understand, making it easy for us to provide content (both media and text) that would allow them to develop a website with the look and feel we wanted. They are just the right balance of website knowhow and flexibility in their thinking.
