One launch across Android, iOS and web
A consumer product designed to launch on three platforms on the same day, with identical features and offline support for the flows that matter most.

A representative scenario that shows how we approach this kind of product, rather than an account of a specific engagement.
The scenario
A consumer product reaches more of its audience when Android, iOS and web users can all start on the same day, and it is simpler to support when every platform offers the same features. This scenario sets out to release on all three platforms together, keep the feature set identical as the product grows and make the core flows work without a connection.
Objectives
- Release on all three platforms on the same day
- Keep features identical across platforms after launch
- Support the core flows without a connection
Design targets
- Release
- Same day, all platforms
- Offline
- Core flows supported
- Quality
- One shared acceptance suite
- Experience
- Native on each platform
Our approach
This scenario involves two of the five layers: the applications layer, where parity is designed in, and the cloud and agents layer, where a single API and the sync engine keep every platform consistent.
One specification, native on every platform
What we build
One feature specification, a shared design system, native implementations on Android and iOS, a web app built on the same component model, and one acceptance test suite that every platform must pass.
Key decision
Native implementations give each platform the experience its users expect, and the shared specification and tests keep them identical.
One API with offline-first sync
What we build
A single backend with a sync protocol, conflict resolution at the data layer and a local store on each platform.
Key decision
Solving sync once at the data layer keeps all platforms consistent, rather than each app handling offline behaviour in its own way.
Delivery path
An indicative sequence. The length of each phase depends on the product, and we agree it with you during discovery.
- Phase 1
Specification and data model
A single source of truth for features, states and sync rules before any screen is built.
- Phase 2
Parallel development
Three platforms built side by side and tested against one acceptance suite.
- Phase 3
Offline sync
Conflict handling, recovery and testing across poor and intermittent connections.
- Phase 4
Launch
Store submissions coordinated for a same-day release, with monitoring in place from the moment of release.
Outcomes the approach is designed to deliver
Three platforms, one release day
Android, iOS and web go live together, so the whole audience starts on the same day.
Features that stay identical
A shared specification and test suite keep the platforms aligned release after release.
Core flows that work offline
Users complete the essential tasks without a connection and sync as soon as they reconnect.
Key takeaway
Parity is decided at the data model, long before the interface is designed.
