Product Design for Web & Mobile Apps

Take your web & mobile app to the next level with a responsive design and digitally transform your business.

Product Design Process

These are the steps we’ll take to make your product a reality. Depending on the stage your product currently is, we will adapt the steps, their order and the length. To ensure that our collaboration goes smoothly, we’ve layout a thorough plan to get to know you and your project:

Design Process: Step 1

Discovery Workshops

Unravel the truth about your business and its needs during a 2-day Discovery Workshop. You can meet us online or onsite to tell us about your project, your vision, and what you’re aiming for.


Give us all the information you have on your product (in any format) and we’ll prepare a 1 to 2-day workshop of exercises and activities. No need for countless meetings and back-and-forth emails.

Allows participation

Different from a simple meeting. Workshops uncover what your project really is about. With structured activities, everyone has the same value as participants, and the chance to share and create ideas. We’ll evaluate ideas, select and prioritize them for the Minimum Viable Product.


We’ll understand the business goals, user needs, and technical feasibility, to set groundwork and project milestones. We’ll create a rough version of a user flow mapping and roadmap.

Inventory Management and Procurement App

In the workshop, we discussed the client’s product goals and the business angle, we bounced ideas off, and planned the first MVP. In four months we built a user-friendly MVP with an inventory complex enough to handle the database, but simple enough for a non-techy user.

Design Process: Step 2

Information & Planning

Together we’ll build a clear roadmap of your app. Planning the architecture and user flows will give you an organized and clear structure so that your users understand where they are and where to go next in your application.


The emphasis on the initial kickoffs will not only tell us must-haves and nice-to-haves but also the roadmap for the development, the client’s timeline, and a prioritized backlog for the first sprint.


We start with information architecture. We organize the ideas, knowledge, and discoveries from the workshop. We estimate and budget the product. We’ll set user journeys, site maps, user stories, navigation, and content.


We can also take the role of Product Owner. By planning the product’s process, we set the testing time, delivery, devise the timeline, and how it's going to happen. We check and analyze your competition’s new features.

A Web & Mobile App For The Hr Industry

To deliver an innovative user experience, and appeal to corporations, we started an intense and thorough planning: 120 hours of design workshops and in-depth analysis of the product. The PM was a consultant and translator for the technical and business stakeholders. In just 2 months we delivered an MVP with a novel idea and new features for the product.

Design Process: Step 3

UX Research & Audits

Involve your users in the product design process to base your app on real insights. User research shows you the user’s behaviors, needs, and motivations. Then take actions to improve user experience. UX interviews help develop a better software product.

Existing apps

With research and evaluation, in-depth interviews, and surveys, we’ll audit your app from a user’s perspective and score it based on intuitiveness, strengths, weaknesses, readability, and user-friendliness.

Real data

To understand the user, we gather data and make informed decisions and not guesses of what they think, need, or how they act.


Analyzing functionality and usability points out what should be improved. We propose which changes will solve the problems, with graphic representations of all the elements and functionalities.

A Healthcare-oriented Web Application

To overhaul an existing app, we conducted extensive market research. The data showed users with a wide range of devices and resolutions (720x1280 to 360x640) and slow internet. We developed a lightweight app (only 0.7 MB), with a brand new interface using client guidelines. The application is available in multiple languages and increased by 8 African countries.

Design Process: Step 4

UX Design & Testing

Take your business’ prototype app for a test drive. A prototype design is a functional and clickable app that can be navigated through. Testing will verify your assumptions early on and address any key pain points in advance.


Test the app to evaluate functionality with a few users. We ask them to use the app for a certain goal, and then analyze how they navigated through it.


Developers, designers, and end-users review the app and user flow, and give feedback. This shows us where to improve.

B2C Web and Mobile Parking Platform

A 2-year-old app written in legacy code and based on 15 servers, with poor logic, system architecture, documentation, testing processes, and server-to-server communication. We automated the testing functionalities and facilitated development with 2,000 unit tests. Server requests now take 30 milliseconds. The app is now easy to scale and supports more users and markets.

Design Process: Step 5

UI Design & Branding

Create a beautiful and understandable interface to delight your users, with a new digital product or revamping an outdated app. A design that meets the industry’s standards, with a brand identity to speak your values and unique selling propositions.


The previous prototype will turn into a well-designed and colorful app, personalized on your brand’s concept and values, to build trust with your users.

User friendly

We deliver responsive and accessible user interfaces that allow more people to access it from different types of devices with different needs.

3D Interior Design Web App

This web app is accessible online with no installation. For a truly customer-oriented solution, app stability, tip-tier UX/UI, and integration with external assets, we sed BabylonJS, one of the best 3D engines to help us maintain stability and high performance. Very quickly, it gained a four-digit number of active users and became a big fish in the architecture industry. By 2018 it was sold for $19.8M.

What clients love about working with us

  • valuable expertise

    We found it really valuable to be able to bounce our ideas off the Monterail team. They challenged us to think, reevaluate initial assumptions and even say “no” to some of them. We loved the extent of their expertise and topics we’ve covered: from design to choosing the tech stack and establishing the final project scope.

  • professional and beautiful design

    It took Monterail six weeks to deliver us a beautifully designed app for iOS and Android. I didn't even know it was possible! Each stage of the development was conducted professionally and in a timely manner: from the concept, through the implementation to final steps.

  • impressive tech and business approach

    Due to their business-wise approach, we were able to answer questions which we wouldn’t have asked on our own. And the support from the tech lead was impressive. I would recommend Monterail to all our partners and people from the industry.
