Next time you start working on a new mobile app, consider using a fully-coded react native starter kit, to speed up your development. At Instamobile, we build react native templates, to help mobile developers and small business owners launch their apps faster. We’ve compiled a list of beautiful React Native templates, that allows entrepreneurs to focus on their product, rather than on reinventing the wheel, by rewriting the boilerplate code every app has (like user authentication & sign up, Facebook login, Firebase integration, etc.).

For the current framework for comparing free, premium, and production-ready options, read The Ultimate Guide to React Native App Templates. This page remains a product-oriented shortlist.

If you’re a mobile developer like me, you’ve already heard about the new toy everyone is playing with these days: Flutter – Google’s open source SDK for building native apps for iOS and Android from a single codebase. In other words, it’s Google’s competing horse against Facebook’s React Native, to say the least.

In this article, we curated a list of the best Kotlin starter kits that are available as of the time of this writing. Kotlin is the new cool kid in town: Google’s new programming language for coding up Android apps. It brings up a lot of value on the table, through amazing modern features such as higher order functions and lambdas, which were not supported in Java. With Kotlin, Google is shifting the paradigm towards functional programming, which can also be seen as a response to Apple adopting Swift.

Kotlin is extremely powerful and Android developers should adopt it as soon as possible. An effective way of ramping up on Kotlin is to download an existing free starter kit, to learn practically. By getting used to the Kotlin syntax and by making a few changes to existing open-source Kotlin templates, an Android developer can quickly incorporate the new language.

Apple Pay and Google Pay can make mobile checkout faster, especially for commerce, marketplace, restaurant, delivery, booking, and service apps. Old React Native tutorials often mention Android Pay or abandoned Payment Request wrappers. For current production work, use the maintained payment SDK for your provider and keep privileged payment logic on your backend.

This guide focuses on Stripe's React Native SDK because it supports PaymentSheet and platform wallets through the same production payment flow.

React Native payment integrations have changed a lot since early checkout packages wrapped a few native payment APIs. For production apps today, Stripe's React Native SDK and PaymentSheet are the safer default for card payments, Apple Pay, Google Pay, saved payment methods, and multi-method checkout.

The mobile app should never own payment secrets. It presents checkout, receives client-safe values, and shows status. A secure backend creates PaymentIntents, validates amounts, handles webhooks, and finalizes orders.

One of the most important aspects of designing a mobile app consists of colors. We’re introducing a Color Framework – Chameleon, which can be used by mobile developers to create iOS apps. It provides support for amazing flat colors, color gradients, complementary colors, colors from images, hex codes, and many other features. The framework can be used in both Swift and Objective-C and it’s open-source on Github.
