A 30-year coaching vision, distilled into an app
Ben Stork - a fitness coach with over 30 years of experience - built the B.E.N. programme to help teenagers understand the connection between their metabolic health and mental wellbeing. The app had to make students more self-aware without feeling like they were being checked up on.
That meant one of the hardest design constraints in software: fully anonymous data that still gives each child personalised insights - and gives teachers a clear view of class and year-group wellbeing, not individuals.
Teenage-first design
Simple, clean and uncomplicated - a daily check-in that takes seconds, not a chore to be avoided.
Class-level insight
Staff monitor the wellbeing of a class or year group as a whole - spotting trends without singling anyone out.

The build - PWA, dashboards, reporting and data.
The technical graft behind the friendly interface
Working with our partner Mohunky LTD who owned the client management, design and UX. We built everything underneath - the native apps, the APIs, the dashboards and the gamification engine that keeps young users coming back.
Anonymous by design
Anonymous sign-up and recovery. No student is identified in the system by any personal information - ever.
One codebase, two stores
Native iOS and Android apps built with C#, XAML and .NET MAUI - one team, one source of truth.
Store-compliant sync
Carefully crafted background services keep scores, streaks and content in sync - without tripping platform policies.
Gamification engine
Streaks and monthly badge challenges that turn daily check-ins into a habit young people actually enjoy.
Rules builder
Administrators define custom app behaviour from user scores - with version-controlled rule sets for streaks and challenges they can track over time.
The Flux Capacitor
Time-sensitive challenges adjusted in real time in the future and the past - perfect for both QA teams to test gaming features.
Simple screens. Serious engineering underneath.
Five of the screens that make B.E.N. feel effortless - each one backed by real-time telemetry, offline-friendly storage and an API layer built to scale.
In schools, and getting positive feedback
The app rolled out to a select number of schools at the start of the academic year. Students found it easy to log and track their wellness; staff are confidently monitoring the wellbeing of year groups.
And the work doesn't stop at launch - it's a 2+ year partnership, with new features, SDK updates and store policy compliance handled for the life of the product.
“[hayman.dev] have built my website and my app: Biorhythms.Exercise.Nutrition Ltd. Completely new territory for me, they have been brilliantly supportive and patient while guiding me through the process from concept to delivery. I cannot recommend them highly enough.”
