Amazing and talented people. I’ve worked for both client and agency side and can can say their partnership is amazing. They truly care about ongoing operations and not just ending it at a project level. Highly recommend! Message me if you want specifics.
John Andesilich's Review Sourced from Google
I own a marketing firm in Troy MO and I recently met with Calvin at Sketch Development Services to discuss a software development project I have been thinking about pursuing. He was very nice, easy to speak to and even though his field is a bit out of my knowledge base, he was able to explain things in a way that made perfect sense. I look forward to working with him and his team in the future and recommend anyone looking for a software or app development company to give them a try.

Impressed with their expertise and quality of work, we also trusted Probey with our CRM development project as well. Thank you to the entire Probey Services team for your professionalism and support.

Dedicated Developers Reviews & Testimonials

Mobile App Development Review from Robert Miller
I lost over $125,000 to developers who couldn't deliver so when I came to Dedicated Developers, I wasn't just looking for a dev shop, I was looking for a reason to trust again. They earned it fast. Their Idea To App Blueprint took everything scattered in my head and turned it into a clear, structured roadmap that actually made sense. Within six months, they delivered a sleek, fully functional MVP for our AI-powered homework assistant something a previous team couldn't pull off in over a year. What really set them apart was how early they brought in their ASO experts not as an afterthought, but from day one because they weren't just thinking about building an app, they were thinking about setting us up for a strong launch.Every deadline was met. Every question was answered. Every milestone felt like a shared win. As we approach launch, I can already see the difference a truly invested team makes the foundation is solid, the product is polished, and we're going to market with confidence we never had before. Dedicated Developers didn't treat this like a contract they treated it like a mission. After everything we went through before finding them, that meant everything. If you're serious about bringing your app idea to life and you're done gambling on the wrong team, this is the partnership that will change the trajectory of your product.

Mobile App Development Review from Ben Connors
As CEO of a relationship-focused mobile app company, I partnered with Dedicated Developers to build a dating platform centered on meaningful, long-term connections not casual swiping. I needed a true full-cycle partner, and they delivered. Before development began, they invested time in understanding the vision and created detailed product blueprints. They asked thoughtful questions, challenged assumptions, and scoped each phase carefully, ensuring smooth execution as the platform expanded. Their cross-functional team project manager, developer, UI/UX designer, QA specialist, and app store marketing expert consistently delivered milestones on time and handled complex feature requests with structure and clarity.Since launch, the app has achieved steady download growth, strong engagement and retention, and positive app store ratings a testament to the scalable, high-quality foundation they built. What stood out most was their true product-level ownership. They didn't just execute specs they contributed ideas, challenged assumptions, and helped refine decisions I hadn't fully considered. Their detailed blueprinting before each phase created clarity and saved significant time in execution. They treated the platform like their own product, and that mindset made a meaningful difference throughout a long, evolving engagement.

Mobile App Development Review from Akshath Goyal
As an advisor to a fintech startup, I've seen firsthand how Dedicated Developers operate at a level beyond typical vendors they truly act as product partners. They successfully architected and built a complex mobile platform combining social media and secure peer-to-peer payments, handling everything from blueprinting to post-launch optimization with strong ownership and technical depth. The result speaks for itself: over 1 million downloads, well received 5-star reviews, and a scalable, compliance-ready foundation. Their disciplined execution, transparency, and long-term thinking make them a valuable partner for any ambitious fintech venture.

Off the Grid has had a longstanding developer partnership with Admios. Recently, the client trusted Admios with building a complex React Native POS system and a guest order-ahead app. Given the complexities of the project, Off the Grid wouldn't have chosen any other agency to work with. The Admios' developers did an excellent job, the management was proactive, and the software quality is exceptional. Admios is highly recommended. (Verified via email)
