Your store, or your idea, as an iOS and Android app.

One Flutter codebase for both platforms, or native Swift and SwiftUI when the app needs it. Store apps talk to WooCommerce or Shopify through the store's own API. Apps with no store behind them get their own Laravel backend. Four to six weeks, fixed price, source in your repository.

Questions about mobile app development

Do we need a custom app or an app builder?

A builder like Tapcart, Shopney or MobiLoud is right for many stores at $100 to $1,250 a month. You need custom when the checkout has its own logic, the app has to work offline, you want your own push infrastructure, or you are tired of paying monthly. A custom app pays for itself inside two years once the builder tier you need costs around $800 a month. The app builder guide has the arithmetic.

Can you build an app that has no store behind it?

Yes. Booking, delivery, membership and content apps get a Laravel backend and an admin panel, built with the app.

Flutter or native?

Flutter when you want iOS and Android from one codebase and one budget. Native Swift and SwiftUI when the app leans on iOS-only features, or when the feel of the app is the product. We say which in the quote.

Who submits it to the stores?

We do, under your developer accounts. Listing copy, screenshots, privacy forms and review replies are part of the build.

What happens after launch?

Thirty days of fixes are included. After that, the App care retainer at $299 to $499 a month covers OS updates, API changes and store resubmissions.

Can you take over an existing app?

Yes, after a two-day code review that ends in a fixed quote for the work needed.
