Mobile app development company in New York

Native development fits an app that depends on deep device features, demanding graphics or complex background work. You maintain separate codebases for iPhone and Android, so changes need attention on both. Flutter is another cross-platform option: it uses Dart and draws its own interface, which suits a heavily branded design that needs to look identical across platforms. A progressive web app is worth considering for a staff tool; it skips store review, though it will not appear in the stores unless packaged for them.

React Native shares a codebase across iOS and Android and suits apps centred on accounts, forms, bookings, payments or content. We build with React Native and add native modules where needed. We go fully native when the product needs deep device features. To choose, look at the tasks users must complete and the device features those tasks actually require; that gives us a basis for selecting an approach without adding separate codebases unnecessarily.

For a state or local government app, the applicable accessibility rule requires WCAG 2.1 Level AA. We design the app screens against that standard, so accessibility is part of the screen work from the outset.

Checkout needs to match what you sell. We set up store purchases for digital content, features and subscriptions; physical goods and services need another payment route, such as a card gateway. Stripe is available to businesses in the United States, so it is an option to consider for that checkout.

Bring the details that will help us agree what the app needs to do.

• First releaseList the tasks users must complete in the order they will do them.
• Existing systemsNote the website, booking software or other systems involved, whether each has an API and who holds admin access.
• Developer accountsStart registration in your company’s name and prepare the D-U-N-S number needed for organisation verification.
• Privacy policyHave a policy that matches the data the app collects; Apple requires links in the listing and app.
• Account deletionIf users can create accounts, plan how they will start deleting them inside the app. Deactivation alone is insufficient.

• !

  Wrapping a website without adding useful app features risks rejection. Plan what people will be able to do in the installed app before submitting it.

• !

  Asking for notification permission at first launch can waste the request. Ask when the benefit is clear, such as after an order.

• !

  Adding an analytics or advertising SDK without updating privacy answers creates a mismatch. Include the SDK’s data collection in Google Play’s Data safety form.
