AppMakers USA Reviews & Testimonials
Eliana Lubofsky Teacher at SAM School
5.0★
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!
Roei Schneider IT at Ness
5.0★
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.

Web Design Review from Jo Maney
DDC has been an excellent partner since we engaged with them in 2023. The DDC team worked with us to completely redesign our website and work to provide ongoing digital marketing services. The DDC team has been responsive, proactive, and thorough with their work. They are also very transparent about how they operate and how much time special projects will require. We have referred DDC to several clients and partners thanks to their outstanding process and product. DDC is a very professional, creative, and well-organized team.

Web Design Review from Sapna Doshi, Ph.D.
My experience working with Design in DC was incredible. Everyone was friendly, approachable, and seemed to genuinely care about helping create the best possible website for my business. They were also invested in making sure the process was one in which I enjoyed and felt taken care of. The regular meetings made me feel like I was a priority and that progress was continually being made. I so appreciated the attention to detail in regards to the user experience. The collaboration in understanding my wishes and desires for the website and user experience was met with patience and paying attention to detail on my behalf. Not only were they taking my suggestions but offering their own to help me maximize the potential of my website. The design and functionality is more than what I could have imagined. I know, undoubtedly, that the work that Design in DC did for me will help my business grow. After wasting money in years past on website designers, I was worried I'd be doing hte same here. I was wrong. I don't think I'll ever need to search for another website designer group again. I would recommend this group to anyone I know. Thank you, Design in DC! It was an absolute pleasure working with all of you!

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 Review from Google

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.

Jessica Dally Review from Google

Jessica Dally's Review Sourced from Google
"We loved working with badpixel!We had already started talking with some potential locations and we needed to quickly establish our logo and branding. With the questionnaire that kicked off our discovery, we were able to capture what we were looking for and it was clearly understood as we went into our first review and really liked what we saw. After a few modifications, we had our logo and style guide allowing us to start working on our social presence while the badpixel team continued to work on our Square website setup.Once the site was ready, they walked us through everything and we were able to jump in and take control! Getting a website up just before the holiday season was huge, it lead to our first sales and profit!"
