Use All Five Reviews & Testimonials

Web Development Review from Rostislav (Rusty) Klibaner
We can't possibly recommend Use All Five enough! Our office came to the Use All Five team wishing to redesign and overhaul our website, which greatly needed functional and structural upgrades. From the get-go, Kara, Michelle, Levi, and their whole team were kind, supportive, and communicative with all of our questions and concerns. Moreover, they were endlessly inventive with their ideas, recommendations, and overall approach (not to mention always willing to be flexible and work within our budget). They took in all of our feedback and needs, and then masterfully incorporated our requests into a product that went beyond our greatest expectations. The resulting website was nothing short of amazing: featuring dynamic, wonderful colors, ease of navigation, and accessibility for all users. We're so lucky to have worked with Use All Five, and cannot wait to collaborate with them again in the future!

Digital Services Review from Kerrie Mitchell
We worked with Use All Five on the redesign of our flagship site. It was an incredibly complex project and website with a large number of stakeholders, but UA5 managed it all with ease, grace, organization, and good humor. The site they created for us was gorgeous, and we continue to work with them on ongoing maintenance. I was incredibly thankful to have them as partner on this undertaking and really couldn't have imagined doing it without them. Would highly recommend their services.

eCommerce Development Review from Anonymous
Our experience with Use All Five on our e-commerce project was outstanding from start to finish. They built us a custom Shopify-based solution that perfectly captured our brand aesthetic while delivering powerful functionality. The team's technical expertise and creative vision resulted in a website that not only looks incredible but also drives conversions. Since launch, we've seen a substantial boost in online sales and received numerous compliments from customers about the user experience. Use All Five proved to be reliable, innovative, and genuinely invested in our success. I wouldn't hesitate to work with them again.

The Touchzen team was amazing!! They were always responsive and ready to incorporate our feedback. The quality of their work was great and the tips they gave us during development were extremely helpful. We would gladly work with them again.

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.

Flyaps Reviews & Testimonials

Python Django Review from Andrew Stetsenko
We partnered with Flyaps to build the GlossaryTech Chrome Extension from scratch, including the backend for tech terminology analysis. The goal was to help recruiters, sales professionals, and other non-technical specialists in IT quickly understand the technical terms they encounter every day.The first release shipped back in 2017, long before today's AI tools were available off the shelf. Flyaps built a custom tokenization layer on top of NLTK library to resolve the ambiguity problem - distinguishing "Go" the language from "go to the shop," or "Swift" the framework from the adjective, while also correctly recognizing multi-token terms like "Ruby on Rails" or "Amazon Web Services". It was a pragmatic, precise solution that made the extension genuinely usable from day one.The outcomes have validated that early bet. GlossaryTech now holds "Featured" status in the Chrome Web Store, has passed 25,000 downloads, and consistently serves 10,000+ weekly active users and 2,000+ daily active users. For a niche professional tool, that level of organic, sustained engagement is rare - and it traces directly back to the technical foundation Flyaps put in place.Beyond the engineering, what stood out was how Flyaps engaged with the product itself. They contributed to architecture decisions, flagged edge cases early, and treated scope conversations with honesty rather than upsell. Communication was straightforward throughout, deadlines were met, and the codebase has held up well as we've extended the product over time.I'd recommend Flyaps to anyone looking for a partner who combines solid engineering with genuine product thinking. They've been central to GlossaryTech's success and continue to be a team we trust.

Software Development Review from Dariia Ryzhova
Our collaboration with Flyaps has lasted for several major projects, of which I personally worked with them on two. I am very satisfied with the level of expertise (both technical and domain), the involvement and responsibility of the teams, and the quality of delivery. We successfully brought 2 major products to life together. Flyaps teams have diverse specializations, so I had the opportunity to attract consultants from different fields: software developers, including high-level architects, DevOps, QA, and business analysts.The teams have a modern technology stack and are experienced in Agile development. This allowed for smooth integration with internal teams and processes. It is also important to note that Flyaps provides technical consulting on demand, and this was very valuable service as well. Overall, I can recommend working with Flyaps as a reliable and high-quality partner.
ТОВ ХОТНАЙТС's Review Sourced from Google
Flyaps delivered outstanding results for our e-commerce store! They built a visually stunning and high-performing website that perfectly captures our brand. Since launching, our site speed has improved by over 60%, and we've seen a noticeable increase in our conversion rate. Their team's technical expertise is top-notch, and the new admin panel they created has made managing our operations so much easier. I am happy to recommend this team of professionals.
