Mobile App Development Review from Amanda Chalofsky
My experience with Simpalm was very good. They made a full prototype of our neuro-wellness app so we could show partners and investors what our system looks like. It matched our brand and showed the flow in a simple way. Their communication was steady, they stayed on time, and they explained things clearly. The prototype helped people understand our idea fast, and it moved our project forward. I felt supported the whole time.

Mobile App Development Review from Matt Rudnick
Working with Simpalm has been a really positive experience. We hired them to handle the frontend development of our mobile app for iOS and Android, while our backend was already in place. From the start, their team communicated clearly, stayed organized, and met every deadline we set. They were flexible when we added new features, and their designer’s input really helped improve the look and usability of the app. I appreciated how reliable and easy they were to work with having a U.S.-based team made communication smooth and fast.

Web Design Review from Steve Dickson
Simpalm partnered with us to redesign, develop, and deploy our corporate website, providing strong value and creativity throughout the process. Their design phase was particularly impressiveusing Figma, they collaborated closely with us, provided creative infographics and visual assets, and delivered polished branding and wireframes that aligned with our goals. This allowed us to confidently defer much of the creative direction to them while still having opportunities to review, provide input, and iterate over alternatives.Project management was handled through a dedicated project manager, with virtual meetings and a collaborative project site keeping communication organized. From the outset, we agreed that achieving a high-quality design was more important than strict timelines, and Simpalm supported that approach. The design phase was timely and well-executed, and overall, they remained responsive and delivered the key milestones.Most importantly, the website is now fully deployed in production and reflects the design sessions and specifications we set. The end result is a responsive, user-friendly site that enhances our branding and capabilities. What impressed us most was the value Simpalm delivered: strong design and creativity, great collaboration, and a willingness to bring forward ideas while working with us to refine the final product.

We worked with Fuselab on multiple projects and each time they took care to detail our needs. The designs they produced were thoughtful and visually striking. They especially have a very talented illustration team and we enjoyed the many illustrations they produced for us. They have fair pricing, fast response time, and a full team of talented UI/UX designers. I'd highly recommend them to anyone looking for those skills.

The team at Coretechs is phenomenal. We needed to transition our custom app and databases to a new developer rather quickly due to an unexpected discontinuation of service. Coretechs handled all of the details and made the transition absolutely seamless. They communicated their progress and timelines the entire time. Since then I've had them do some modifications to our app, which they turned around right away. Everyone I've talked to there is super friendly and super knowledgeable. I'm looking forward to working with them on future improvements.

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.

We worked with Digital Charter to build a custom AI solution for our business and honestly it exceeded expectations. From the start, they really took the time to understand how we operate and what we were trying to accomplish instead of pushing some generic, off-the-shelf product.The solution they built was tailored specifically to our workflows and has already saved us a ton of time. What stood out most was how responsive and collaborative their team was throughout the entire process. They explained things clearly, kept us in the loop, and delivered exactly what they said they would.If you’re looking for a team that actually understands AI and knows how to apply it in a practical way for your business, Digital Charter is the real deal. Highly recommend.
