1. React Native

React Native is an open-source framework that allows developers to build mobile apps using React. It enables developers to write code in JavaScript and deploy it on both iOS and Android platforms. A neat feature of React Native is its ability to render native components, giving a native look and feel to applications. One lesser-known aspect is that React Native can be fully integrated with existing apps, allowing developers to incrementally adopt it.

2. Flutter

Flutter, developed by Google, is an UI toolkit that facilitates stunning, natively compiled apps for mobile, web, and desktop from a single codebase. Unlike its competitors, Flutter uses its rendering engine, which allows for highly customizable UI elements. An interesting fact is Flutter's widget library, which offers a broad range of widgets to streamline your development process.

3. Xamarin

Xamarin is a Microsoft-powered cross-platform app development tool that allows developers to write apps in C#. One of its standout features is shared code—up to 90% of code can be shared across platforms. Additionally, Xamarin.Forms provide a way to design UI elements using XAML, which is particularly beneficial when targeting multiple devices without sacrificing performance.

4. Ionic

Ionic is a hybrid mobile development framework that combines Apache Cordova with Angular, allowing for the development of apps with web technology like HTML, CSS, and JavaScript. A lesser-known fact is that Ionic can also be combined with popular frameworks like React and Vue.js, which further broadens its accessibility and application scope.

5. PhoneGap

PhoneGap is an open-source mobile development framework backed by Adobe. It allows developers to utilize HTML, CSS, and JavaScript to create apps. A typical underappreciated feature is its vast plugin repository, which enhances functionality by allowing access to device features like the camera, accelerometer, and file system. This makes integration much simpler!

6. NativeScript

NativeScript allows developers to build native mobile apps using TypeScript or JavaScript. One surprising aspect of NativeScript is its true native performance, as it compiles to native code rather than just running in a web view. This framework provides access to all native APIs of iOS and Android, allowing developers to leverage the full capabilities of these platforms.

7. Sencha Ext JS

Sencha Ext JS is reputed for its powerful data management capabilities, offering numerous pre-built UI components. An interesting fact about Ext JS is its built-in support for modern web standards and Progressive Web Apps (PWAs), enabling users to build applications that can function like native apps on the web. This makes Ext JS a popular choice for complex enterprise applications.

8. Appcelerator Titanium

Appcelerator Titanium provides a JavaScript-based platform for building native mobile applications. A unique aspect of Titanium is its ability to compile JavaScript code into native code, ensuring maximum performance across platforms. Moreover, it has a rich ecosystem of modules that allow easy integration with various cloud services, streamlining backend connections.

9. Cordova

Cordova (previously known as PhoneGap) is a mobile development framework that allows for the creation of apps using HTML, CSS, and JavaScript. The ability to wrap HTML5 applications in a native app wrapper enables access to device features, making it easier to transition web apps to mobile platforms. This flexibility can be a game-changer for leveraging existing web applications.

10. Framework7

Framework7 is a free and open-source mobile HTML framework that enables developers to create hybrid mobile apps. A relatively lesser-known feature is its ability to create apps with a native look and feel using nothing but HTML and CSS. It also includes built-in support for popular UI components, making it highly versatile for rapid application development.
