      Mobile App Development Review from Eliana Lubofsky

    • Alexa Ginsberg
      Alexa Ginsberg Social Media Manager at Nanobébé
      5.0 ★

      Startup Review from Alexa Ginsberg

      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
      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.

      Mobile App Development Review from Max Levchin

      We've partnered with HDWEBSOFT who have created our app using .NET. The feedback from our customers we've received has been overwhelmingly good. We had heard positive things about the idea even before we released the app, so it's encouraging to see those comments continue once it has been out. HDWEBSOFT was set up from the start. The design team was outstanding; they completed the job on schedule and within our allocated budget. They followed a well-defined procedure that was in place.

      Mobile App Development Review from Beranger Dumont

      Junkies Coder delivered an excellent mobile app for BPI Real Estate Poland, combining strong technical skills with a clear understanding of our business goals. From the start, they were professional, responsive, and focused on user experience. The app was designed with a clean, modern interface that made property browsing, filtering, and agent contact smooth and intuitive. Built using React Native, it launched seamlessly on both Android and iOS platforms, with features like advanced search, map integration, push notifications, and bilingual support. The team managed the project efficiently using agile methods, kept us informed with regular updates, and quickly implemented feedback. They also ensured strong backend integration with our property database and CRM. Testing was thorough, and the final app was stable, fast, and secure. Since launch, we've seen a noticeable increase in user engagement and property inquiries. Junkies Coder also provided great post-launch support, helping us refine features and monitor performance. Overall, they exceeded our expectations and delivered a product that added real value to our business. We highly recommend them for any mobile app development needs.
