AppMakers USA Reviews & Testimonials
Awital Ifrah Program manager at Masa Israel journey
5.0★
Cross-Platform Review from Awital Ifrah
Masa came in with a pretty loose idea and AppMakers helped turn it into something solid. What I appreciated most is they didn't overcomplicate it or try to make it into some giant monster platform. They listened, asked smart questions, and helped us focus on what would actually matter for alumni and current participants. The end result felt thoughtful and realistic. I'd definitely work with them again.

Moishi Stern Customer support at Madlan
5.0★
Startup Review from Moishi Stern
We create live events. We wanted a site that shows what we do without making people dig. AppMakers listened, trimmed the fluff, and gave us pages that read fast and look good on a phone. The quote form asks the right things and our team can update galleries without calling a developer. They stayed on schedule and answered messages the same day. The whole process was calm and clear. We already see better inquiries. It feels like a real upgrade, even before the full rebuild.

George McKerrow CEO at Ted's Montana Grill
5.0★
Mobile App Development Review from George McKerrow
ELEK+RIK has worked on improving our React Native mobile app. We had the skeleton of an app, but they were able to do an end-to-end re-design of each of the main pages. Since then, they`ve successfully implemented around ~20 different features on our mobile app. We share a spec and design, they provide an estimate and occasionally some design options, then when completed create a PR on GitHub. Their code is well-organized, easy to follow, and rarely do we have to go back-and-forth about bugs. They are also excellent communicators - carefully following threads on Slack, effectively communicating design and engineering tradeoffs, and even producing a 10m Loom video walking through a diagram. Their communication is top-notch. They are super easy to work with even though we are on very different time zones. And, I am impressed at the speed and execution of their development.

Web Development Review from John Riley
ELEK+RIK was tasked with creating a website for our company from scratch. They were professional, communicative, and dedicated to delivering an exceptional website that perfectly captured the essence of our company while exceeding our expectations. They are a talented, reliable, and customer-focused web design and development company that I would highly recommend to anyone.
