      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.

      We have been working with M TECHUB since 2023 on software and application development projects, and they have become a valued technology partner to our company. Their team has consistently demonstrated strong technical capabilities, responsiveness, and a genuine commitment to delivering quality work. They communicate well, are receptive to feedback, and work collaboratively with us to solve challenges and continuously improve our applications.

Based on our experience since 2023, I am very comfortable recommending M TECHUB to companies looking for a dependable software development partner.

      Markovate are passionate about building products for startups helping to shape ideas into reality. They have been more than a developer, a true partner to us, even supporting with fundraising. Equally, they built with minimal reliance, considering easy adoption by our developers when selecting a tech stack.

      David Dorough's Review Sourced from Google

      I read reviews of almost 100 companies and spoke with reps from 5 before finally going with Appingine for my first app. I'm sure you can pay more for less quality from a different company but why would you? They were easy to work with and quick to respond to questions. They split the charges by stage of development like every professional company should. I needed to make several changes during development and the cost was reasonable. Anthony was awesome and helped me along every step of the way. Apple has more stringent requirements than Google and Appingine was able to get the app published on both stores. Looking forward to more projects with them. Once again, don't pay more for less, go with Appingine!

      Mobile App Development Review from DJA

      We paid $117,000 across two contracts $68,000 for development and $49,000 for marketing to Naked Development for a consumer-ready iOS and Android app and a full marketing funnel. They delivered neither. We originally requested delivery by Black Friday, the most critical sales window for a parent-focused consumer app. Naked Development proposed December as an alternative. That deadline was their own suggestion. They missed it. We extended to January, then February, then April, then issued a formal written Notice of Breach before giving them one final deadline the following June. Every deadline was missed. We were over 300% over timeline. When we finally handed the codebase to a second development firm, the app would not build on either iOS or Android. We paid thousands just to get it running enough to assess the damage. The contracted team was never fully assembled. Tickets were put on hold without explanation. Subscription management, the most critical feature of the app, was broken for months and never fixed by Naked. The commercial video Naked produced was unusable by launch, as cultural references had gone stale during the delay. We are software engineers who have led teams of over 100. These were not minor issues. They were basic, objective engineering failures. When we raised breach concerns with founder John Driscoll, his response was "let's just let our lawyers talk about it." We are aware of more than a dozen other former clients who experienced similar issues. Do not recommend.

      Mobile App Development Review from Mimi Bouchard

      I hired Naked Development in 2022 to build a new version of my mobile app. I paid $203,000 upfront (spread over six months essentially everything I had saved from my first year in business), and was told the app would be completed in five months, by Fall 2022. Instead, the project turned into nearly a year of delays, almost done updates, and declining involvement from their team. My very small internal team and I ended up doing much of the project management and QA work ourselves because progress had stalled so severely. Despite constant reassurances, no functional product was ever delivered. By mid-2023, I hired multiple external development teams to assess the code. Every single one independently concluded that the app was non-functional, unstable, not scalable, and could not be launched. They warned it would crash immediately and required a complete rebuild. I then hired a neutral third-party auditor with zero connection to any agency and his report confirmed the same findings. After paying over $200K, I had nothing usable. When I factored in delays, internal time lost, expert audits, and the cost of rebuilding from scratch, the financial impact to my business exceeded $500,000. After multiple attempts to resolve the situation privately were unsuccessful, I filed a lawsuit, which is now a matter of public record (Superhuman Inc. v. Naked Development). The case is set for trial in early 2026. While litigation is never something a founder hopes for, at a certain point it became the only responsible path given the evidence and the financial damage. I strongly recommend extreme caution when considering this agency.
