    How to create free apps

    Prima di enter the live of the tutorial and spiegarti how to create free apps, it is my duty to provide you with some preliminary information on the case in question. First, know that to be able to create applications, it is essential to know the programming languages reference, or at least have a smattering of it.

    The most popular programming languages ​​on Android are Java e XML, while for the side iOS abbiamo Swift (launched by Apple in 2014) and Objective-C (historical language on which iOS apps have been based from the beginning): for further information, I refer you to reading my specific guides on how to start programming, how to create a program, how to learn Java and how to program in Java. Further detailed tutorials on the subject can also be found by doing some research on Google, on specialized Internet sites on the subject.

    Programming languages ​​can be used through special programs designed, precisely, for the development of applications. The software belonging to this category are essentially divided into two types: the SDK and independent commercial solutions.

    The SDK (acronym for Software Development Kit), are tools made available by the companies that manage the operating systems (Google, in the case of Android, and Apple, in the case of iOS), thanks to which it is possible to make the most of the platform which they go to contact, allowing you to manage everything in detail, optimizing each function and performing various tests.

    Independent software, on the other hand, as the definition itself suggests, is made available by third-party companies and allows you to develop content within an integrated environment. Usually, they are easier to use and allow you to work on a single project that can be exported in different formats, as a package compatible with multiple platforms, depending on the license you have.

    How to create a free app for Android and iOS

    How to create free apps and make money

    You have finally managed to create free apps and now you would like to understand how to publish them on the digital store of the mobile platform of your interest and earn thanks to the work done? I'll explain it to you right away. Contrary to what you may think, the hardest part is the one you have already faced.


    How to create free apps

    In regards to Android, to proceed with publishing your app on the Play Store, the first move you need to make is to create a developer account and associate it with yours Google account.

    The operation, from the cost of dollars 25, it's very simple: all you have to do is go to the Google Play Console page and send your application to Google, uploading the related APK file, managing its metadata (i.e. version and system requirements) and thinking about the commercial part (title, description, etc.).

    As for the possibility of earning money thanks to the apps you publish on the Play Store, you can do it in various ways: you can choose to make your apps available paid, or for free but with advertisements inside, thanks to which monetize.

    You can also evaluate the possibility of proposing in-app purchases, through which to offer additional content to users, after downloading, upon payment of a specific sum of money. For more information about the use and operation of Play Console, I refer you to reading the official guide.

    iOS / iPadOS

    How to create free apps

    If you have developed an application for iOS / iPadOS, instead, to be able to publish it on App Store, Apple's digital application store for mobile platforms, you need to get a developer account.

    The operation, unfortunately, is not free (it costs $ 99 per year) and must be carried out through the appropriate web page on the website Apple Developer Program, by clicking on the button Start Your Enrollment, which is located at the bottom.

    The app publishing process you developed requires the use of Xcode and App Store Connect. The first is the software you need to develop the app and will also allow you to submit it to App Store Connect. The latter is Apple's web platform that will allow you to enter all the information on the app which will then go online on the App Store.

    As for the monetization discourse, the same rules apply as for Android: you can choose to make money with your app by making it available paid, to allow free download with advertisements or, again, proposing in-app purchases to unlock additional content. For further details, I refer you to the consultation of the website dedicated to the Apple Developer Program.
