App development company in Washington, D.C.

For an app centred on accounts, forms, lists, maps, bookings, payments or content, a cross-platform build is worth considering. We use React Native to share a codebase across iOS and Android, adding native modules where a feature needs them. Shared code keeps the work focused across both platforms, while the screens still need to suit the people using each device.

Native development is a better fit when the product depends on deep device features, heavy graphics, complex background work or new platform features at launch. The trade-off is separate codebases to build and maintain. We go native when those device needs call for it. That decision should follow the tasks your app must perform, particularly where those tasks depend on the phone itself.

Flutter is another cross-platform option. It uses Dart and draws its own interface, which suits a heavily branded design that should look identical on both platforms. Your team would need to be comfortable working in Dart; consider that alongside the freedom you want over the interface.

For a state or local government app, the ADA Title II rule requires WCAG 2.1 Level AA. That changes the screen design and testing work: we design the app screens with that standard in view and test the result against it, instead of leaving accessibility until the store submission.

Payment flow also follows what you sell. Stripe lists the United States as a country where businesses can sign up to accept payments. For physical goods or services used outside the app, we plan a card-gateway checkout; digital features and subscriptions used in the app have different store purchase requirements.

A few practical details will make the first scope discussion more useful.

• List the actions users must complete in the first release, in the order they will do them.
• Start developer account registration in your company name; organisation verification needs a D-U-N-S number.
• List the website, booking, CRM, ERP and payment systems involved, their APIs and who holds admin access.
• Prepare a privacy policy that matches the data the app collects; it needs links in the app and store listing.
• Keep developer accounts, signing access and the code repository in your business name.

  Putting sign-up before any value

  Let people explore without logging in when the app does not depend on significant account-based features. Give them a reason to create an account when they reach a task that needs one.

  Asking for notification permission immediately

  Ask when the benefit is clear, such as after an order. On Android 13 and later, notifications remain off until the user allows them.

  Adding an analytics or advertising SDK without revisiting privacy answers: Update Google Play's Data safety form to include data collected by third-party SDKs in the app.
