      Mobile App Development Review from Domenic Fraboni

      We couldn't be more pleased with our experience with TouchZen. They took over a bad situation left behind by our previous development team and have been able to continue to build new features while cleaning up the old project. We have been very pleased with their developers responsiveness as well as the project management. I would highly recommend working with them for any of your web or mobile app development needs.

      B2C Apps Review from Brett Lassig

      We have been extremely impressed with TouchZen's development team behind the Get Cover Mobile App. Their approach has been collaborative, and responsive to the needs of our warranty and claims environment. The app is intuitive for end users while still delivering the robust functionality needed on the backend, especially around claims processing, and real-time updates. Their diligence has made a significant impact. Features like streamlined claim submission, status tracking, have enhanced both customer satisfaction and operational efficiency. Overall, this highly capable and professional development team has delivered quality work and stands behind it. We look forward to continuing to build and scale with them.

      Mobile App Development Review from Dr Asa Frey

      They worked on our app and continue to work on it to this day. We originally had a bad experience with various developers and ended up with a bunch of code and no functioning app - touchzen took the code and audited it and made it work and it work great now. Can't complain - still going to work with them and I would recommend to anyone who wants it done right.

      Software Development Review from Mario Mariani

      We worked in collaboration with Longwave for several projects, including the new version of our Junior Full Stack Developer Course, also having them onboard as teachers. Moreover, I've been working with some of them in another company as I was part of a senior management team. But in the end they are a software development agency, so I am happy to write this review of Longwave Studio to which we outsourced the implementation of our new product that is still in stealth mode. Longwave Studio exceeded our expectations in every way, from planning and designing to developing and delivering the product. They worked closely with our team to understand our needs and vision, and they developed a comprehensive plan to bring our product to life. They were also incredibly responsive to our feedback and made changes as needed to ensure that we were happy with the final product. Longwave Studio's team of experienced developers is highly skilled and knowledgeable in the latest software development technologies. They used their expertise to develop a robust and scalable platform that meets all of our needs. We are extremely pleased with the resultl that Longwave Studio brought to us. It will definitely help us to streamline the business processes and become very effective in what we do. We are confident that we would not have been able to develop such a successful platform without Longwave Studio's help. We highly recommend them to any company looking for a reliable and experienced development partner.

      Software Development Review from Hannes Rössler

      I worked with the Longwave agency on a software project for US physicians involving employees from several teams on our side. The collaboration with Longwave was very easy and straight forward. Everyone in their team had a great can-do attitude and the solution suggestions and execution were extremely professional. Longwave was responsive to all our request and made to find pragmatic, yet reliable ways of executing. Throughout the entire project the agency made proactive proposals how to best move forward and sticked to all their committed timelines. When we moved the project to maintenance mode several different options were offered and Longwave was really helpful in making sure we found the best way to continue collaborating. It was great to have a variety of skills in the agency, including design, backend, web frontend and mobile development. I can strongly recommend this agency for any sort of software project.

      Blockchain Review from Salvatore Campus

      Longwave Studio's work on the "Unblended" project has been nothing short of exceptional. This complex endeavor, involving the creation of a blockchain-based software solution, demanded a diverse skill set, and Longwave Studio delivered on every front. The backend development is robust and reliable, providing a strong foundation for our blockchain-based system. The team exhibited a deep understanding of blockchain technology, ensuring data security and integrity were paramount. The database design is efficient and well-structured, enabling seamless data management and retrieval. The meticulous attention to detail in optimizing database performance greatly enhances the software's overall efficiency. Frontend development, both for the web and app interfaces, is nothing less than stunning. Longwave Studio's designers and developers have crafted an intuitive and visually appealing user experience that sets "Unblended" apart in its industry. Communication and collaboration throughout the project were outstanding. Longwave Studio was responsive, accommodating, and receptive to feedback, ensuring that our vision for "Unblended" was fully realized. The "Unblended" software has already made a significant impact on our operations, thanks to Longwave Studio's exceptional work. We couldn't be more pleased with the results, and we highly recommend their services to anyone seeking top-tier software development. In a nutshell, Longwave Studio's development of "Unblended" has set a new standard for excellence in blockchain-based software, and we are excited to continue our partnership for future projects.

      I had the pleasure of working with Debut Infotech for DeFi development, and I am extremely satisfied with their expertise and service. Their team utilized a comprehensive suite of tools, including smart contract generators, DeFi protocol integrators, and liquidity pool management tools, all of which streamlined the development process. They not only helped us build secure and scalable decentralized finance solutions, but also provided automated yield farming and staking platforms that significantly boosted user engagement. Their focus on security, with built-in auditing tools, gave me confidence throughout the project. I highly recommend Debut Infotech to anyone looking for reliable, efficient, and innovative DeFi development.

      After many frustrating weeks of looking for a development team to help bring my idea to life, I was fortunate enough to find the team at Modall. From the very first call I knew I'd found the right partner to help me build my app. They proved themselves to be much more than "just" a dev team and much more like a trusted co-founder and partner. They cared as much or more about the project than I did. MVP was delivered on time and on budget with regular and frequent communications throughout the process. We have active users and the feedback has been positive. I'll continue to iterate and improve the app with the incredible guidance, vision and partnership of the amazing team at Modall. - Mike, Founder - HuddleBooks

      As a founder looking for a technical partner to build our MVP, Modall was exactly what I needed. They felt like part of my team and worked with me every step of the way. Im based in Toronto so having a local team I could actually talk to made a huge difference in speed and communication. They took my idea and turned it into a real, working product. If you're a founder looking for an MVP development company, I can't recommend Modall enough.
