Should Your MVP Be a Mobile App or a Web App?

"Do I need a mobile app?" is one of the most common questions we hear. The short answer: probably not for v1.

The Default Should Be Web

A responsive web app accessible from a mobile browser validates your product just as well as a native app for most use cases. And it ships 2–3x faster.

Build a native mobile app only if you can check at least one of these boxes:

You need device hardware — camera, GPS, accelerometer, biometrics

Your users are mobile-first by necessity — field workers, delivery drivers, people who can't use a laptop

Offline functionality is core — your app needs to work without internet

Push notifications are central to the UX — not a nice-to-have

The App Store is your acquisition channel — you're relying on App Store search

If none of these are true, start with a web app.

The PWA Middle Ground

Progressive Web Apps (PWAs) are web apps that install on mobile home screens, support push notifications, and can work offline. They're built with standard web technologies but feel native.

For many MVPs, a PWA is the sweet spot:

• Ships as fast as a web app
• Can be "installed" on mobile
• Supports push notifications
• No App Store review process

When You Do Need a Native App

If you've validated the product with a web app and mobile-specific features are now blocking growth, that's when to build native.

Our recommendation: React Native. One codebase, two apps (iOS + Android). Shares code with your Next.js web app. Your team doesn't need to learn Swift and Kotlin.

The App Store Tax

Shipping on the App Store means:

• 15–30% cut of in-app purchases (Apple and Google)
• 1–3 day review delays for every update
• Strict guidelines that can result in rejection
• Users need to update the app to get new features

For a payment-heavy product or a product that needs fast iteration, this is a significant constraint.

The Mobile Reality Check

Ask where the user is when the pain happens. If they are at a desk, in a spreadsheet, or coordinating with a team, a web app is usually the right first move. If they are on a job site, in a car, scanning receipts, recording workouts, or working offline, mobile starts to make sense.

Also be honest about iteration speed. App Store review, release approvals, push notification setup, and device-specific bugs slow the learning loop. If you are still discovering the core workflow, that delay matters more than native polish.

The Decision Framework

Your situation	Build
B2B SaaS, productivity tool	Web app
Consumer app, social features	Web app (PWA) or React Native
Marketplace, two-sided platform	Web app
Delivery, field service, logistics	React Native
Health tracking, fitness	React Native
Gaming	Native
Anything with a complex form	Web app

When in doubt, ship a web app, validate, then build mobile once you know exactly which mobile features your users need.
