Self-serve, 1 to 3 days
Possible if everything is already in place
Same-day technical launch only works if the brand uses a default template, accepts the builder's defaults, has Apple Developer and Google Play Console accounts already provisioned, and is prepared to wait through App Store review. In the real world, brands that customise even a little tend to take one to two weeks on a no-code builder.
Custom, 4 to 9 months
Discovery, design, build, QA, submission
Discovery runs three to six weeks. UX design runs four to six. Engineering for iOS and Android runs ten to sixteen weeks in parallel. QA adds three to four. App Store and Google Play submission takes one to three weeks plus review time. A £75,000 plus build typically lands at six to nine months by go-live, before scope creep.
Talmee, two weeks
Why it is fast and what it covers
Week one: discovery workshop with the brand, UX design in Figma, brand asset gathering, Apple Developer and Google Play Console account setup. Week two: React Native build, manual and device QA, store-listing assets, App Store and Google Play submission. Day fourteen: live on both stores. The pace works because the React Native commerce foundation, Storefront API integration, push retention plumbing, deep linking, Shop Pay integration and analytics layer are already built and tested. Every new app reuses them.
Where time actually goes
Discovery and UX, not engineering
On a Talmee build, five to seven of the fourteen days are discovery and design. The actual engineering window is short because the foundation is reused. On a custom build, the long pole is integration testing across loyalty, subscriptions and reviews, plus the design-handoff cycle.
