An App Walkthrough Screen is a slider screen which allows the user to learn everything about the features of a mobile app when they open the application for the first time. We can implement this feature in a React Native application in multiple ways. In this React Native tutorial, we describe how we implemented the Walkthrough Screens in all of our React Native Templates so that you can speed up your app development by reusing our open source code.

Sign in with Apple is a common requirement for React Native apps that offer third-party login options such as Google, Facebook, LinkedIn, or Amazon. It also gives iOS users a privacy-friendly authentication option that works well with Firebase Authentication.

Optional imports are useful when a React Native app has platform-specific code, feature-gated screens, optional assets, or native modules that should only load in one environment. They are also easy to misuse. Metro still needs to know what files can be bundled, so arbitrary runtime strings are not a good import strategy.

Push notifications are one of the highest-leverage features in a React Native app, but they are also easy to get wrong. Firebase Cloud Messaging can deliver messages to Android and iOS, but iOS still depends on APNs, modern Android requires runtime notification permission, and every production app needs a trusted backend to send notifications.

This guide focuses on the current architecture: the mobile app requests permission and stores device tokens; Firebase owns delivery; your backend sends messages with Firebase Admin SDK or FCM HTTP v1.

Phones, tablets, and foldables have status bars, notches, camera cutouts, rounded corners, gesture home indicators, and navigation bars. A React Native screen that looks fine on one simulator can still hide content under system UI on another device.

The modern solution is react-native-safe-area-context. The older SafeAreaView exported from React Native core is deprecated and should not be the default choice for new work.

Deep linking lets a React Native app open directly to a specific screen from an external URL. It is useful for passwordless login links, push notifications, marketing campaigns, referral invites, order tracking, chat threads, and content shared from the web.

Instagram-style filters are a product feature, not just an image effect. A good React Native implementation lets users pick or capture a photo, preview filters quickly, export the selected result, upload it safely, and recover when a filter library or device GPU behaves differently across platforms.

Older tutorials often recommend a single native filter package as the default. For production apps, choose the filter stack deliberately and test maintenance, export behavior, Android/iOS parity, and upload integration before committing to it.

React Native projects collect several kinds of local state while you work: Metro cache, Watchman watches, node_modules, CocoaPods, Gradle build output, and Xcode DerivedData. Cleaning all of them at once can fix some painful build issues, but it can also create new problems if you delete lockfiles or update native dependencies accidentally.

This guide shows a safer cleanup order. Start with the smallest cache reset that matches the symptom, then move down the checklist only if the problem remains.

Mobile banking, electronic transactions and online payments have been a growing trend in the modern world. It will not surprise you that every buy and sell transaction will take place online through the internet in the near future. Take a look at our curated list of the best free and premium Finance UI Kits, to use as inspiration while developing your next FinTech app in React Native. Mobile banking application, e-commerce websites and apps are increasing on a day to day basis. Every business companies are developing their own financial software and application. A large number of people already use mobile banking and finance apps to complete transactions, check balances, and explore financial services or financial product options. Financial apps have made it easy to manage your financial information and keep track of personal expenses and savings. As a result, you can leverage these Financial UI kits as inspiration for our next personal finance app project. Due to an increasing number of mobile banking applications, tools and kits are necessary for their quick and efficient designs. Therefore, we provide you with a list of Financial UI kits which will help you get started with your very own business finance application.

This article is focused on finance screens. For the broader React Native UI kit decision, read Best Free React Native UI Kits. If you need a full production starter instead of design inspiration, compare options in The Ultimate Guide to React Native App Templates.

Drawing directions in a React Native app usually starts with a simple map polyline. A straight polyline is enough for connecting two coordinates visually, but real turn-by-turn-looking routes need a routing service such as Google Routes API, Mapbox Directions, HERE Routing, or a backend you control.
