Responsive check
OpenCart 3 and 4 default themes are responsive; heavily customised or very old themes may not be. If your store needs zooming on a phone, fix the theme before converting.
Carts and sessions
OpenCart keeps the cart in a session cookie. Inside the app, cookies persist between launches, so customers find their cart where they left it — test that a cart survives closing and reopening the app.
Checkout
Guest checkout reduces friction in an app. Test every payment extension; redirects to external gateways must come back inside the app.
SEO URLs and the start URL
With SEO URLs on, use the clean home URL. Avoid starting on a URL with route= parameters unless it's the page you really want.
Extras
Use bottom tabs for Categories, Cart and Account, and an offline screen for flaky connections.
Frequently asked
Does OpenCart have an app builder?
Third-party extensions exist; a web to app converter is the quickest route because it uses your existing storefront.
Will OpenCart extensions work inside the app?
Frontend extensions behave as on mobile web.
