Is it realistic to build a mobile app in 8 weeks?

Yes, for a focused MVP with 4-6 core features, a cross-platform framework like React Native, and scope locked before development starts. It's not realistic for marketplace apps, fintech, healthcare, or any product with regulatory compliance requirements, which typically need 16-28 weeks minimum.

What's the biggest risk to hitting an 8-week timeline?

Scope creep after development starts is the single most common cause of an 8-week timeline slipping to 16 weeks or more. Every added feature after week 2 needs a formal scope-change conversation, not a quiet yes, or the whole schedule shifts.

Should I use native or cross-platform to hit an 8-week timeline?

Cross-platform, almost always. Building separate native iOS and Android apps roughly doubles engineering time because every feature gets built and tested twice. A cross-platform framework like React Native lets one team ship to both platforms from a single codebase, which is what makes an 8-week timeline achievable at all.

Does app store review affect the 8-week timeline?

Yes, budget 1-2 weeks inside your 8-week plan for App Store and Google Play review, not on top of it. Apple's review typically takes 24-48 hours but can extend to a week with resubmissions; Google Play review is usually faster. Submitting a build with obvious guideline issues is the most common cause of delay here.

What should I have ready before development starts to protect the timeline?

A locked feature list, one decision-maker who can approve design and scope questions within 24-48 hours, brand assets (logo, colors, copy), and a clear answer on which third-party services you'll use for auth, payments, and analytics. Missing any of these typically costs 1-2 weeks once development is underway.
