Short answer
Convert your URL to an app when your website already works well on phones and the app's job is to bring that experience to the home screen and Play Store — it takes minutes and stays in sync with the site. Rebuild in React Native or Flutter when you need native-feeling UI throughout, real offline work, background tasks, Bluetooth or heavy device features, and have the budget to maintain a separate codebase.

|---|---|---|
| Time to first release | Same day | Weeks to months |
| Codebases to maintain | Your website | Website + app |
| Content/feature updates | Instant | Store releases (or OTA updates) |
| Native UI & animation | Web | Native |
| Offline-first | Limited | Full |
| Bluetooth, background sync, widgets | No | Yes |
| Skills needed | None | Mobile developers |
A common path
Launch a URL app first. Measure installs and what app users do. If the app becomes central to your business, rebuild the most-used screens natively — the URL app will have proved the demand and shown you which screens matter.
FAQ
Will users notice it's a web app?
Only if the site feels like a website. Most of that is fixable on the site — see make it feel native.
