App Development Technologies

iOS App Development

While Android has an open-source code, iOS has closed source code. This means that iOS works on Apple devices only. The development team might use Swift or Objective-C. Also, iOS developing tools include: iOS SDK, or Software Development Kit, is integrated with the Cocoa Touch UI framework. The framework provides graphical elements, user interface controls, and others. XCode is the official integrated development environment (IDE) for iOS app development. Swift Playgrounds is a development environment for Swift. TestFlight is an online service for over-the-air installation and testing. This online service allows to test your apps and collect valuable feedback before the app release. Advantages of iOS mobile app development:

  • Revenue. As you may already know, Apple users spend more money on app purchases compared to Android users.
  • The number of devices. As we said, iOS powers Apple devices only. Because of this, your app should fit the limited number of screens and devices.
  • UI design. Apple provides developers with a detailed style guide for the app UI. The team needs less time, making it more affordable in the app design stage.

The strength of flutter is that it has a single codebase which can be utilized to build apps for mobile, web and even desktop. It’s an open source platform while it’s a primary method to create apps for fuchsia.


Xcode is an IDE (Integrated Development Environment) of Apple that can be used to develop applications in several languages. Specifically and among others, it allows the creation of apps for iOS mobile devices, such as iPad, iPhone or iPod, something that we are expert at Appstudio.


Java is an object-oriented programming language created in 1991 and published in 1995 by Sun Microsystem (acquired by Oracle in 2010), with the intention that programmers write the code only once and execute it on any device.


For macOS or iOS, the best option is to do it in Swift. The most used programming languages are over 20 years old. But that which at first sight can be considered a disadvantage is a great advantage. Why? Because it is a language adapted to the needs we currently have.

Objective C

Objective-C is much less compromising with errors, has a complicated syntax and also offers certain concepts that are complex for programmers that come from other languages. However, the main libraries for iOS are written with Objective-C.

React Native

React Native is one of the most fashionable technologies at the moment. When developing an app in React Native, the code we write is the same for the Android and iOS versions. However, if not handled well, it could ruin the whole development process.

Android App Development

To create Android apps, developers use Java, C++, and Kotlin programming languages. Furthermore, Android developers use the following advanced Google development tools: Android Jetpack, a set of pre-build Android components. Firebase is known as a comprehensive mobile app development platform. Android SDK development kit, connected with Android Studio, an integrated development environment. Advantages of developing Android apps:

  • Open system. Android developers receive access to more features, restricted in iOS apps.
  • Design. Developers use extensive Google design guidelines for developing an intuitive user interface.
  • Fragmentation. On the one hand, we may consider fragmentation as a disadvantage, but you can develop apps for a broader range of devices, including wearables, TVs, in-car systems, and more.
  • Release. In comparison to iOS, Android apps are easier to publish to Google Play. The whole process may take just a few hours.

Android Kit

SDK is the acronym for “Software Development Kit”. The SDK brings together a group of tools that allow the programming of mobile applications.


Java is an object-oriented programming language created in 1991 and published in 1995 by Sun Microsystem (acquired by Oracle in 2010), with the intention that programmers write the code only once and execute it on any device.


Kotlin is a statically typed programming language, that is, it is the virtual machine that infers the type to the variables and, therefore, does not have to be specified. It is a language that runs under the Java Virtual Machine, so it has the same performance as Java, without penalizing this aspect at any time.


The strength of flutter is that it has a single codebase which can be utilized to build apps for mobile, web and even desktop. It’s an open source platform while it’s a primary method to create apps for fuchsia.

Material Design

Material Design is an Android-oriented design language created by Google, supporting onscreen touch experiences via cue-rich features and natural motions that mimic real-world objects. Designers optimize users' experience with 3D effects, realistic lighting and animation features in immersive, platform-consistent GUIs.

Mobile Backend Engineering

The backend in a mobile application system is that centerpiece, which we also call the web server engine, which centralizes all requests made from mobile devices that need to write, collect data from a database, records, shipments, etc. The backend can be developed in several very diverse and different technologies. There are large mobile application development systems that are developed in different languages. For example, we have facebook that its backend is developed mainly with PHP; we have linkedin or paypal, that your backend system is implemented with the powerful and versatile node.js, etc. In AppStudio, we prefer to use the powerful node.js as a preference when implementing robust backend systems and for app development. Its versatility, efficiency and unlimited resources in the market, make it an optimal choice today for any mobile application system that wants to scale and have a long journey. Experience indicates that this language exceeds its objective. Either for mobile app development systems or for complex web page systems, which can scale in the future, removing the processing limitation. In addition, backend systems can be easily deployed in the cloud. From AppStudio, we use both large projects and small software projects such as Heroku or Amazon WebService to host these centralized systems.

Python DJango

It is a highly recommended web system that energizes quick improvement and spotless and sophisticated structure. It is the only framework that “by default” comes with an active management system, ready to be used without any configuration


Powerful empires have been made with PHP, such as Yahoo and Facebook. PHP is a well-known open source language, appropriate for web advancement and that can be installed in HTML. It is popular because a large number of web pages and portals can be created with PHP.

Node JS

NodeJS is an open source JavaScript (which is why the JS flag is included) that is designed to generate highly optimized applications. Taking advantage of the V8 engine allows Node to provide a server-side runtime environment that compiles and executes codes at incredible speeds.

QA and Testing

When a user runs a software, no matter what type, it only sees a small part of it. The outside, the design, and how it behaves while it is being used are the visible elements. However, in the shade there is a work that is not perceived, but that is essential for a correct start-up of that product and to maintain its quality during its operation. An important part of that work that is not seen is in quality control. Once the software has been developed and the design adjusted, it is necessary to test the operation of the final product. This process is somewhat more complex than simply using the program and waiting for failures to arise. Structural quality is measured with applications specifically created for this purpose.

Our App Development Approach

Native App Development

Applications developed on the native programming language (Java, Swift, Objetive-C…) of the device. These applications are 100% platform dependent. Therefore, we must develop and maintain a complete application for each target platform (iOS, Android or others).

Hybrid App Development

Applications developed in HTML, CSS and Javascript that run on an abstraction / framework layer (Apache Cordova, Ionic, React Native, Capacitor ...) that provides access to the terminal resources in a neutral way to the type of device. Therefore, through this paradigm, a single common application is developed and then prepared for each platform (with small functional adjustments if necessary).

Mobile App Development

Smartphones and tablets are already part of everyday life for most people. Just look around in the streets, restaurants or the subway, to see how crowded they are. According to a study, 84% of users say that smartphones are more important to them than computers and television. Another study shows that mobile traffic already exceeds desktop traffic in North America. Considering this data, it is clear that it is a relevant channel for marketing.

With their specific services and functions, mobile applications have become relevant tools in the daily routine. Calendars, emails, chats, maps, and games, among many others, accompany people every day, at all times. Companies that manage to enter the world of applications generate a mutually beneficial relationship with users, loyalty and giving stability to their businesses.
