Planning, Development and App Creation for Snowball

Snowball community logo

Introduction

We were approached by our client, Simon Sansome, who had a brilliant idea for a new app design and needed a team with the expertise and know-how to bring it to life.

Well, he came to the right place! Inspired by the premise of Simon’s app concept: to create a “TripAdvisor-style” experience for people with disabilities, making it easier to find accessible venues. Our team at b4b got to work.

The app was launched in early 2022 and has gained an international following, with reviews praising the way in which the programme makes it easier for those with physical disabilities, mental health issues and learning disabilities to explore and travel with confidence.

The Challenge
Based on his own experiences, and the challenges he has faced as a wheelchair user, Simon developed the idea for Snowball long before the app itself was realised.

With a dream to inspire confidence in others and remove some of the unknowns that could make activities - like going out to dinner or visiting a new venue – a frustrating experience, Simon had already started running a Facebook page. This became a place where people could share their reviews of how certain establishments catered to (or failed to cater to) their specific needs.

From here, the idea for an app was born, aiming to make this information even more accessible and easier to find - it was just a case of building it!

Building Snowball

A detailed breakdown of how we got the ball rolling for the Snowball app - from conception to creation!

01

Plan to suceed

Our software team started the app-creation process with several idea-generation sessions, aiming to begin with a strong foundation of possibilities. These sessions were held both with Simon, and internally, to collate all the best ideas which we thought were essential for the app to thrive.

One of the first hurdles to overcome was the app’s name. The name is always such a huge part of any brand, so we wanted to make sure we got it right. In fact, our idea-generating sessions were so successful, we also mapped out phase 2 and 3 of the app build! We were, you might say, on a roll!

02

Putting the framework in place

Once we had an understanding of what needed to go into the app, the software team started to create the “wireframes”. These are the app’s framework; they lay out how the different functionality aspects will look on each screen.

After we were happy that the wireframes included everything on our list of requirements, we started to overlay the final design on top.

During the design stage, we made sure the app itself was fully accessible, using specific colours and fonts to create an easier experience for users with disabilities such as visual impairment.

Before sending the app off to our development team, we created a full end-to-end prototype. This was fully interactive and allowed Simon to navigate through the whole thing as if he were using the final app.

We always view this as a crucial final step in the design phase, making it easy for clients to check that they are completely happy with the app’s appearance and usability.

03

Developing the app

After the designs were signed off, we handed the project over to the development team. This is when everything really started coming together; they got to work building the app and the accompanying customer relationship management system (CRM).

Module by module, the app was released back to our software team to test. Every time we received a module, we became more and more excited for the final product to be delivered.

Features & functionalities of the Snowball app

Snowball is an innovative mobile platform designed to empower the disabled community by providing a central hub for reliable, user-driven accessibility information. The app enables users to discover, review, and share insights about venues and services based on their accessibility standards.

Key features include:

  • Community-Driven Reviews
    Users can contribute by adding and reviewing any venue, rating them on a tier of accessibility. This crowdsourced approach ensures that information stays relevant, transparent, and reflective of real experiences.

  • Verified ‘Snowball Assessments’
    Beyond user reviews, Snowball conducts its own professional assessments of venues’ accessibility, known as Snowball Assessments. Each assessed venue receives an official Snowball Accessibility Rating, offering an objective measure of inclusivity that users can easily view within the app.

  • Interactive Accessibility Map
    The app includes an intuitive, interactive map that allows users to locate nearby accessible venues, restrooms, fuel stations, and parking spaces in real time. This feature helps users plan journeys with confidence and ease.

Together, these tools make Snowball a trusted and comprehensive resource, helping to remove uncertainty and promote equal access in everyday life for people with disabilities.

 

The Result

In early 2022, we successfully launched Snowball to the public. Since its release, Snowball has amassed over 15,000 users and 7000 reviews and is making positive waves throughout the disabled community and wider public.

In October 2025, Snowball featured on Dragon's Den and received £80,000 in investment from all five Dragon's.

Snowball has also won six recognised awards, including the Santander Global Award 2024, the De Montfort University Entrepreneurship Award 2024, and the TBAT Innovation Challenge Award 2025, and has gained late-stage recognition in many others.

We were thrilled to work with Simon to make Snowball become a reality, and are extremely pleased with the growing success of the app. We look forward to working with Snowball in the future to help fulfil even more of its huge potential.
