UI/UX Design Review from Wladimir Wolinski

Communication was smooth either through our teams communication channel or with the project manager via email. We were in daily contact with the UX/UI designer in form of dailies or when we had to clarify some questions. With the project manager, we had a short conversation every 2 weeks to clarify all possible questions.We personally love to work in a very process-oriented way. Because when we understand how to do something, we usually know how the end result can look like. With Digis, we also had the feeling that they knew what they were doing and how to do it. Every next step was planned from the beginning. If something didn't work in line with our processes, we could readjust it.We were basically satisfied with everything.

Both the developer and tester have exceeded expectations. Their performance is excellent. Together they eliminated bugs, introduced new features, and ensured that the app is working without problems.

Mobile App Development Review from Angie Tromley-Morales, PMP

We hired Empat to design and build the MVP of House Caddy, a household management app that keeps receipts, warranties, manuals, and repair history in one place, with reminders for expiring warranties and maintenance. The product also helps homeowners prepare a full digital home history for future property transfers.Empat delivered end-to-end work: discovery, UX/UI design, Flutter mobile development, and a Python backend. They implemented a clear flow where users first create home appliances/systems and then attach documents and repairs to each item.A major highlight was Empats AI expertise. AI features simplify the entire user journey by auto-filling appliance details from photos/docs/links, assisting with utility provider setup, and importing contacts to speed up adding contractors. This reduced manual input and made onboarding fast and intuitive.Communication was excellent, with proactive brainstorming, clear sprint updates, and on-time delivery. The MVP is market-ready, early feedback is very positive, and Empat proved to be a reliable, product-driven partner with strong mobile, backend, and AI capabilities.

We were kept informed about the progress of work and we got answers to all of our questions.Our clients love the new design and now they have even better understanding of our services. We have also received many positive opinions from industry specialists.We are very satisfied with the cooperation and its results. There is not much to improve. When we first launched, we found the animations a little too fast and we had to adjust them.Every challenge has been met. Our new website is safe (0 attacks after launch), fast – despite using so many animations (page speed insight analysis showed 86 on the desktop and almost 60 on mobile), and both user- and seo-friendly.
