Why US brands need this

Why mobile apps are a strategic asset for US brands.

Americans spend over 4.5 hours a day inside mobile apps. No web experience comes close to that kind of retention or frequency.

Apple Pay and Google Pay dominate US mobile checkout. Native integration converts much better than web checkout.

HIPAA, SOC 2 and PCI compliance are now table stakes for US healthtech, fintech and B2B apps. Getting the architecture right early saves you 6+ months down the road.

iOS ATT and state privacy laws keep shrinking ad tracking. Your own first-party app data is now the most valuable growth signal you've got.
