Every week, thousands of grassroots coaches plan sessions from scratch

A minute on the touchline: browsing, filtering and running a session straight from the phone.

Your browser does not support embedded video playback.

_>About

The Grassroots Coach set out to give volunteer football coaches professional, age-specific training sessions without the prep time. Most grassroots coaches lack structured resources, which makes planning slow and inconsistent.

The product needed a mobile-first experience: browse and filter sessions, follow instructional animations, and work offline on the pitch. On the backend, subscriptions, payments, analytics, and content management had to scale from local UK clubs to a global coaching community.

>_Challenge

The core tension was simplicity for volunteers versus depth for serious coaches. The app had to work for users with varying digital literacy while still supporting team invites, subscriptions, saved filters, and offline playback.

Scalability was equally critical. The backend needed to handle growing clubs, expanding content libraries, and regional rollout without sacrificing speed or security. We added device tracking that limits each account to two devices, reducing account sharing without adding friction for legitimate coaches.

>>>Process

Apptension built The Grassroots Coach app in React Native for consistent iOS and Android performance. Session browsing, intelligent filters, and offline caching sit on a Firebase backend for authentication, content delivery, and push notifications.

We delivered a custom CMS so administrators can upload sessions, videos, and pricing tiers without engineering support. RevenueCat powers subscription flows. Google Analytics 4 tracks engagement for continuous product improvement.

Delivery ran in structured sprints with demo checkpoints, feedback loops, and QA across supported devices. Jira tracked tasks. Confluence held specifications. Documentation kept collaboration transparent from kickoff to launch.

__>Solution

The result is a coaching platform that saves prep time and raises session quality. Coaches filter by age group, player count, equipment, pitch size, and training objective across 13 youth categories from U6 to U18. Each session includes step-by-step animations available offline.

Club administrators invite and manage multiple coaches, keeping standards consistent across teams. RevenueCat subscriptions unlock flexible access tiers from free to club plans. Push notifications drive engagement with new sessions and reminders. The custom CMS manages content, user access, and pricing in one place.

The Grassroots Coach turned fragmented, hours-long prep into a few taps on a phone. Coaches spend less time planning and more time developing players.
