The challenge
A coaching business runs programmes over messaging apps and PDFs. Clients drop off because progress is invisible, and coaches spend their time copying notes between tools.
Approach
How we would tackle it
- 01
Choose the right platform strategy
Weigh native against cross-platform. For a content and check-in product, a single React Native codebase ships faster and costs less to maintain.
- 02
Design for daily use
Short check-in flows, thumb-reachable actions and reminders that respect quiet hours.
- 03
Make it work offline
Clients log habits without signal and the app syncs safely when the connection returns.
- 04
Release through the stores early
Internal builds every sprint, a closed beta well before launch, and store review time planned into the schedule.
Solution
What gets built
Coach dashboard
Responsive web app to build programmes, review check-ins and message clients.
Backend
Authenticated REST API with background jobs for reminders and weekly summaries.
Payments and privacy
Subscription billing through the stores, encrypted personal data and clear privacy disclosures.

Goals
What we would aim for
Targets we would agree up front and measure, not results we claim.
- Clients complete daily check-ins in under a minute
- Coaches see progress across all clients in one place
- Reliable behaviour on slow or missing connections
- A release process that makes store updates routine
