    • Amanda Chalofsky Owner/Founder at Neuro Speech & Swallowing Services

      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.

Frequently Asked Questions

What services does a UI/UX design agency typically offer?

A UI/UX design company typically helps organizations plan, design, and validate digital experiences for mobile apps, websites, and software products.  

Core UI/UX design services include:

  • UX audit
  • User research and analysis
  • Design systems (visual components, standards, governance) 
  • Interaction Design (IxD)
  • Information architecture 
  • Wireframes and prototypes 
  • User testing

Many also offer design consulting, cross-platform experience design, content writing, branding, and development.

How long does it take to complete a UX design project?

A UX design project takes about 4-6 weeks for a simple digital design with minimal functions and features. In contrast, an enterprise build or SaaS app can take over 20 weeks due to scale and complexity. 

The final timeline will depend on the complexity of your digital design, features, and functions, development method (Agile or Waterfall), feedback loop, and existing user data. Below is an estimated timeline of the UX process: 

  • Discovery and UX research: 1-4 weeks 
  • Information architecture and user flow: 2-6+ weeks 
  • Wireframing and prototyping: 3-5+ weeks 
  • Usability testing: 2-4 weeks 
  • Iteration and refinement: 2-6 weeks 
  • Development handoff: 3-8 weeks 

How much do UI/UX services cost?

The cost of UI/UX design services ranges between $300 and $1,500+ per screen or $25-$200 per hour. The actual price will depend on project type (website design, mobile app design, or product design), feature and design complexity, UX strategy, industry-specific requirements, and the UI/UX design company’s location. 

Below is the average rate of UI/UX design companies around the world:

What factors impact the cost of UI/UX design?

Beyond project scope and complexity, factors like design iterations, turnaround time, compatibility requirements, and ongoing maintenance can impact the overall cost of a UI and UX project. Here’s how each item may add to the overall billing: 

  • Extra design revisions: Additional 10%-25% of the initial costs for every round 
  • Paid tools, plugins, and stock assets: 5%-15%  
  • Cross-platform compatibility: 20%-30% 
  • Fast turnaround timelines: 10%-50%  
  • Ongoing optimization and maintenance: 10%-25% 

What is the difference between a UI design agency and a UX design agency?

The difference between a UI design agency and a UX design agency is their focus. A UX designer prioritizes how the product works and feels, such as user flow and wireframes. On the other hand, a UI designer manages how the interface looks and behaves, including the color scheme and typography. 

You can think of a UX as the architect designing the blueprint and the UI as the interior designer, shaping what people see and interact with day-to-day. 

Here are more details on their differences: 

User Interface DesignUser Experience Design
  • User research and user personas 
  • Usability testing and analysis 
  • User journey maps 
  • Information architecture 
  • Sitemaps, wireframes, and prototypes 
  • User flows 
  • Page layout 
  • Interactive elements (e.g., buttons and menus) 
  • Design system (e.g., color scheme and typography) 
  • Mockups 
  • Graphic design, motion design, and illustrations
