Mobile app or web app? A decision guide for startups

Whether you launch first as a mobile app or a web app affects development cost, how you reach users and how fast you grow. The right answer depends on where, how often and how users will use the product.

The options

Native mobile app

Apps downloaded from app stores with full access to the phone's features.

• Pros: best performance, full access to camera, location and sensors, strong notifications, store visibility
• Cons: higher cost, store review processes, users must install

Cross-platform tools that build for both platforms from one codebase can lower cost.

Web app

Apps that run in the browser.

• Pros: no install, shareable by link, updates go live instantly, findable in search, works on desktop too
• Cons: limited access to some device features, no store visibility

Progressive web app (PWA)

A web app that can be added to the home screen, work offline and send notifications. Some can be packaged for app stores. An economical middle path combining web flexibility with an app experience.

How to decide

Go mobile first if:

• Users use the product often during the day and on the move
• Device features such as camera, location or health data are central
• Notifications are a key part of the value

Go web first if:

• Users work at a desk (most B2B software)
• Winning customers from search matters; see our SEO guide
• You want to experiment and ship updates often; see our MVP guide

A practical approach

Many startups start with a mobile-friendly web app or PWA and invest in native apps once behaviour is clear. Track which channels are actually used; see our UX guide.

Conclusion

Choose the platform by the user's context. Today's decision is not permanent; you can expand as you learn. To prototype without code, see our no-code guide.
