Mobile app development company in Philadelphia

For an app built around accounts, bookings, payments or content, a cross-platform build is a practical place to start. We usually use React Native, sharing a codebase across iOS and Android and adding native modules where a feature needs them. That gives you both platforms without treating every screen as a separate build.

Native development gives you access to deep device features, complex background work and new platform capabilities. It uses Swift for iPhone and Kotlin for Android, so you have separate codebases to build and maintain. Flutter is another cross-platform option: it uses Dart and draws its own interface, which suits a heavily branded design where screens need to look identical across platforms.

A progressive web app is worth considering for a staff tool when store distribution is not essential. It skips store review, but it will not appear in the stores unless packaged for them; on iPhone, it can ask to send notifications only after someone adds it to the Home Screen. Start with the features people need in daily use, then choose the format that supports them.

Your checkout depends on what customers buy. Apple requires in-app purchase for digital content, features and subscriptions used in the app; physical goods and services used outside it need another payment method. Stripe is available to businesses in the United States, so we can set up a Stripe card gateway for those physical purchases and configure in-app purchases and subscriptions where they apply. We also account for storefronts that allow links to outside payment options.

A few practical details make the first discussion more useful.

• List the tasks users must complete in the first release, in the order they will do them.
• Identify your website, CRM, booking or payment systems, their APIs and the people holding admin access.
• Start registering Apple and Google developer accounts in your company’s name; organisation accounts need a D-U-N-S number.
• For a new personal Google Play account, check the closed-testing requirement and arrange testers before production release.
• If the app has a login, prepare a working demo account and live backend for Apple’s submission review.

  Wrapping a website

  Give people a useful reason to install the app. A site placed inside an app shell risks rejection by Apple.

• !

  Blocking access with sign-up

  Let people see value before asking them to register when significant account-based features are absent.

• !

  Asking for notifications too early

  Request permission when the benefit is clear, such as after an order. Android requires the user’s permission before notifications are enabled.

  Forgetting store privacy answers

  Update Google Play’s Data safety form when adding analytics or advertising software, including the data collected by those tools.
