The challenge
A founder needed iOS and Android in market before a funding milestone, with no in-house mobile team and a fixed budget.
Our approach
One cross-platform codebase with native modules where the hardware demanded them, an onboarding flow tested on real users before build, and analytics instrumented from the first release so retention could be measured, not guessed.
The outcome
Both stores approved the app eight weeks from kickoff. Post-launch iteration on onboarding lifted thirty-day retention substantially.
Why this approach
With a funding milestone fixed on the calendar, the deadline made the architecture decision: one cross-platform codebase, with native modules only where the hardware demanded them. Two native apps would have doubled the work for a difference users of a fitness app would never feel.
The other deliberate choice was spending design time before build time. Onboarding was prototyped and tested on real users while the codebase was still small, because onboarding is where consumer apps lose most of their users — and changing a flow in a prototype costs hours, not sprints. Analytics shipped in the first release so that post-launch iteration was steered by retention data rather than opinion.
If you are facing something similar
A store deadline concentrates the mind, but the sequence matters more than the speed: scope tight, test the onboarding early, instrument from day one. The MVP scope worksheet is the tool we use to force those decisions, and the mobile development service covers how we run the build itself.
