Key takeaways
- A progressive web app (PWA) is a website that can be installed and work offline. It is the cheapest and fastest route, with the least device access.
- Native apps for iOS and Android give the best performance and full access to device features at the highest cost.
- Cross-platform frameworks such as React Native and Flutter share one codebase across both stores and suit most business apps.
- Choose based on the features you need, your budget and where your users are, not on fashion.
- Validate demand with the lightest option first, then invest when usage justifies it.
Four ways to build a mobile app
- Responsive website. Works in any browser, no install.
- Progressive web app. A website with an install prompt, offline support and some device features.
- Native. Separate apps written in each platform's own tools, such as Swift for iOS and Kotlin for Android.
- Cross-platform. One codebase compiled to both platforms with frameworks such as React Native or Flutter.
How they compare
| PWA | Cross-platform | Native | |
|---|---|---|---|
| Codebases | One (web) | One | Two |
| App store presence | Limited | Yes | Yes |
| Performance | Good for most content and forms | Near-native | Best |
| Device features | Growing but limited, varies by platform | Wide, plus native modules | Full and first access to new features |
| Relative cost | Lowest | Medium | Highest |
| Best for | Content, forms, dashboards, early validation | Most business and consumer apps | Graphics-heavy, hardware-heavy or platform-specific apps |
Questions that decide it
- Do you need deep device features, such as background location, Bluetooth, advanced camera use or push notifications on every platform?
- Do you need to be in the app stores for discovery or customer trust?
- How demanding is the interface? Complex animations and games lean native.
- What are your budget and timeline? One codebase halves the build and maintenance load.
- Which skills does your team have? Web developers can be productive in React Native quickly.
A staged approach
For a new product, start with the lightest option that tests your core idea, often a responsive web app or PWA. If people use it, move to a cross-platform app to get store presence and better device access. Reserve fully native builds for needs that cross-platform tools cannot meet. This follows the same logic as our 8-week MVP plan: learn first, then invest.
Do not forget the running costs
- Developer accounts and store fees, and review processes for each release.
- Ongoing updates for new operating system versions.
- Backend services, push notifications and analytics.
- Support and testing across many devices.
