    Empat Reviews & Testimonials

    • Angie Tromley-Morales, PMP
      Angie Tromley-Morales, PMP CEO at House Caddy
      5.0

      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.

The solution allows us to monitor client success in real time, visualize key trends, and make data-driven marketing decisions. The Empat team was professional, communicative, and highly attentive to our needs. They quickly understood our workflow and created a system thats both intuitive and scalable. Thanks to their work, weve streamlined our internal processes and gained much better visibility into our clients results. Were very satisfied with the outcome and would definitely recommend Empat to anyone looking for a reliable software development partner.

      iPhone Review from Gabriel Sabadin

      We engaged SolveIt to develop a minimum viable product (MVP) app, including a user-friendly iOS design, an artificial intelligence (AI) model, and a monetization strategy while ensuring General Data Protection Regulation (GDPR) compliance and preparing for future integrations. Despite a tight deadline, SolveIt delivered the app on time and efficiently handled beta-testing within three months, allowing us to gather feedback and launch successfully. We acquired our first 1,000 users within a month of launching the app. SolveIt's team communicated effectively, addressed issues proactively, and maintained a high level of autonomy, bringing diverse expertise that greatly benefited our project. We appreciate the agency's dedication and professionalism.

      From my perspective as a former employee: I worked here for almost a year. Colleagues and staffs here are pretty open-minded but employees are highly underpaid. Also in order to get a job here you must have decent technical skills and English language ability. Pros: nice office, friendly staffs that really take care of employees Cons: underpaid salary
