ANML Reviews & Testimonials

Product Design Review from Manuel Colom
Working with ANML on the Yummly app experience and the Yummly Smart Thermometer (IoT) was an outstanding collaboration. Yummly combined personalized recipe discovery, meal planning, and guided cooking into a highly curated food experience, while the Smart Thermometer extended that ecosystem into connected cooking with real-time temperature tracking and assisted preparation workflows. As Director of UX at Yummly, I worked closely with ANML throughout both initiatives, and they operated almost as a seamless extension of our internal design team. Their work consistently demonstrated excellent design craft, strong product thinking, and a highly collaborative mindset. Beyond delivering high-quality UX and visual design, their contribution helped sharpen and strengthen the overall value proposition of the products by making complex cooking experiences feel approachable, premium, and intuitive for users.

Web Design Review from Nathan Thornburgh
As Anthony Bourdain's partners, we were approached by CNN to create an immersive digital site that would provide a beautiful home for each destination covered by Bourdain's show Parts Unknown. It was a huge task not least because there were already close to 100 destinations to integrate into a usable global site. But also because the site was meant to live up to the beauty and aesthetic of the television program. And it needed to be done in a way that satisfied both our mainstream luxury advertisers (like LandRover, ANA, and more) but also the famously high standards of Bourdain himself. ANML engaged in this 18-month design and build process with outstanding workmanship and creative decision-making. They navigated wildly different and demanding stakeholders. And in the end they built a site that still looks fresh even nearly a decade later. If you want to make lasting work, there is no one else I could recommend more.

Web Design Review from Alex Lacerda
We partnered with ANML to evolve our digital experience in a way that stayed true to our brand while modernizing how we present our products and story. As a company with a long history in music, it was important to find a partner who could respect that legacy while helping us move forward.ANML took the time to understand our brand, our audience, and the role our products play for musicians. They built on our existing foundation and translated it into a more cohesive and intuitive experience that better reflects who we are today.Their team brought strong thinking across UX and design, helping us improve how content is structured, how products are presented, and how users navigate the experience. The collaboration was smooth and highly responsive throughout.The end result is a more polished and modern experience that still feels authentic to our brand. ANML was a thoughtful and reliable partner, and we would highly recommend them.

Mobcoder is a great team to work with. They are professional, responsive, and able to execute any of your development needs. We've worked with several different developers on the team and they all have exceptional character. Definitely recommend working with them!

Software Development Review from Brandon Straza
Mobcoder has been amazing to work with. Their communication as well as their follow through is unlike any other team we've worked with to develop our platform. They were prompt, thought for themself, and brought us their own ideas as well. They worked side by side throughout the entire process. We look forward to a continued relationship moving forward.

Christina Milano's Review Sourced from Google
Luke & Jen and the GJ team have been nothing short of great partners who listen first and then add value and expertise to our vision. We see them as an extension of our team!
Jerry Paffendorf's Review Sourced from Google
Our team at Regrid had an amazing experience working with Gravity Jack.For us, it started with curiosity about whether our nationwide land and property dataset could be viewed and interacted with in AR. A knowledgeable friend recommended we contact GJ and I’m very glad they did.From the first exploratory conversation through project scoping and execution, the GJ team was great to work with at all levels: company leadership; project managers; and hands-on designers and engineers.They took the time to listen, understand, and get excited about our unique business and AR opportunity. More than that, they executed beautifully.A few things that stand out to me:• The weekly project meetings were always something to look forward to — progress, organization, and enthusiasm• I never felt lost in the process or timeline or budget• The collaboration, communication, and design were outstanding• There were always exciting updates we could feel and use and feedback on throughout the project• At the end of the project everything was perfectly wrapped up as a deliverable and the door felt wide open for more anytimeI highly recommend working with them.
Illinois Soybean Association's Review Sourced from Google
Gravity Jack helped us build an amazing AR app. Their workflow is extremely thorough and they will walk you through every step of the process. They excel in many different ways, but the most valuable to us was their initial design phase. They have a core team that will help you get your best ideas on the table so that you can create the best experience possible.
