Alty Reviews & Testimonials

Mobile App Development Review from Ewa Koltunczyk (Karabon)
I recently had the pleasure of working with Alty to develop our mobile app. We needed a developer who was able to translate my vision and provide technical guidance. The experience has been nothing short of outstanding. From the initial consultation to the final product, Alty's professionalism, expertise, and dedication have exceeded my expectations. Alty has demonstrated a deep understanding of mobile app development and was willing to go the extra mile. Their ability to translate my ideas into a seamless, user-friendly, and visually appealing app is truly impressive

Mobile App Development Review from Adam Kubas
Alty did excellent work for our department. The team prepared a high-quality and easy-to-understand development roadmap for Virtual Academy of Bioinformatics. Their positive attitude and willingness to learn made them a pleasure to work with. Overall, I highly recommend Alty for any development role. They have the skills, dedication, and professionalism to excel. Thank you for developing our app.

Dogtown Media Reviews & Testimonials

Web App Review from Michael Paskow
Dogtown media helped to develop a new cross-platform app and web portal for a sleep health study involving insomniacs for the National Sleep Foundation. The team was reliable and developed an excellent experience for end-users. It has been a great experience working with DTM. The team is reliable and communicative. They come up with creative solutions and are always available for any and all maintenance issues that arise. Although I am not well-versed in pricing for app development, I do feel that the pricing may have been a little too steep. That said, the work they have produced is excellent, and I'm very happy I got to work with the team at DTM.

Call Centers Review from John Shammas
We've really enjoyed the time spent with Dogtown and their support in our product initiatives. They have always been readily available to talk through design ideas, technical challenges, or feature improvements. Communication has always been solid, with a reliable stream of beta builds (delivered to our own devices to test out) and detailed patch notes. We look forward to working with Dogtown on more projects in the future!

Fingent Reviews & Testimonials

Web Design Review from Undisclosed
I hired Fingent to create a web-based application for my website's visitors. They communicated their strategy effectively and adhered to our agreement. The pricing was notably low compared to other quotes I received. Ultimately, the project was a huge success, and they continued to provide support even after delivery.

Software Development Review from Alex Burkhead
Fingent brought both attention and creativity to our project. They polished our storyboard and developed the tool we needed. Very responsive and very talented.

Studio Almond Reviews & Testimonials
Holly Bennett's Review Sourced from Google
Studio Almond is a class act; they have supported my firm through various website iterations and pieces of development work; proud to be associated with a home-grown New Zealand brand of such calibre!
Mason Feehan's Review Sourced from Google
We started working with Studio Almond in 2024 after having a challenging experience with the agency who originally built our 3 websites.Since taking over, Studio Almond have provided incredible service with great communication, as well as providing valuable counsel on short-term optimisations and long-term strategy.They've got us out of a few sticky situations swiftly too.I'd highly recommend the team at Studio Almond - good people doing good work.
Cynatra Major's Review Sourced from Google
We’ve worked with Studio Almond for many years now - from initially helping us deliver an award-winning Shopify Plus website to partnering with them on ongoing optimisations that continue to elevate our ecommerce experience.What sets Studio Almond apart is the standard they hold themselves to. They work with integrity, transparency, and a genuine commitment to excellence. At BLUNT, we value technical craft and engineering precision just as much as beautiful design and a meaningful customer experience, and Studio Almond shares that same mindset - never compromising one for the other in their approach to web design and development. That value alignment drew us to them from the start and remains one of the main reasons we continue to work together.What really makes it such a pleasure to work with them though, is that they’re just genuinely great humans, doing great work. We couldn’t recommend them more!
