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

Big Fish Reviews & Testimonials
Eric Wexler Review from Google
5.0★
Eric Wexler's Review Sourced from Google
Working with Big Fish App Development was a fantastic experience. Sara and her team were professional, helpful, responsive, and incredibly easy to work with throughout the entire project. Building an app or software can be a stressful undertaking but Sara really takes an organized approach and explains the process step by step. Her deep knowledge and expertise really showed, and she consistently met deadlines while being flexible enough to work at whatever pace was needed.Big Fish was thorough, and always one step ahead — often thinking of things I hadn’t even considered, which made a huge difference in the App. Her input during the development process was invaluable.I highly recommend Big Fish to anyone looking for a skilled and dependable app developer. If you are coming into this with little AppDev knowledge, just know that Big Fish is fair and trustworthy. I couldn’t have asked for a better team in bringing my app and ideas to life!

I've had really great experiences with Big Fish. Their attention to detail is only surpassed by the solid execution of app development with each project. One of the best app development companies that I've worked with, and I look forward to our next project together.

Wayne Barker's Review Sourced from Google
The Summit team are smart, knowledgable and engaging and made the project fun from the first briefing call. Maybe we could've figured out how to build our Mybridity website in-house (we've seen the adverts!) but I'm so glad we didn't go down that path. We made more progress in less time working with Summit and, as a result, have a growing pipeline of projects.

Roger Walker's Review Sourced from Google
When we came up with the idea of a web portal for searching and booking experiences and activities from across the county, it was clear that a quality, bespoke website was going to be crucial to our business model. The team at Summit worked hard to understand the concept of what we were trying to achieve, helped design our logo and corporate identity and then worked tirelessly to build a robust website for us. They continue to support our ongoing development, offering friendly and knowledgeable advice. Summit are well worth contacting to discuss a new website build, or to offer a boost to your current site

Gene McCreesh's Review Sourced from Google
FIVE STARS!!! 10 out of 10.After more than 30 years in business, I’ve learned the hard way that not all website and SEO companies deliver on their promises. Over the years, I’ve hired multiple companies that talked a big game but never produced real results.Nowadays, having a strong online presence is absolutely critical in the service industry, and Jeremy at Digital Minds has finally gotten us moving in the right direction. From day one, he’s been honest, knowledgeable, responsive, and incredibly easy to work with. He always answers the phone, knows SEO and website marketing inside and out, and consistently over-delivers for a very fair price.What I appreciate most is that Jeremy isn’t trying to drain your budget with unnecessary extras. He puts together a realistic game plan and rolls things out the right way so you get the maximum return on your investment.I can honestly say I’ve finally found my SEO, website, and marketing team. Highly recommend Jeremy and his team at Digital Minds to any business owner looking for real results. 100%. I'm super excited to grow this area of my business with the support of people that know what they're doing.Thank you,Gene McCreeshPresidentMcCreesh Tree Service, Inc.

Jeremy at Digital Minds is fantastic. From start to finish, he was incredibly personable, easy to talk to, and genuinely invested in making sure everything turned out exactly the way I needed. His responsiveness is unmatched — every question was answered quickly and clearly, and he consistently went above and beyond to keep the process smooth. If you’re looking for someone reliable, professional, and truly customer-focused, Jeremy is the one. Highly recommend!
