Android vs iOS: Which is more secure for Mobile App Development in 2019?

It’s been over a decade now and still, two of the most popular mobile app development platforms are trying to prove which one is better. This constant battle between the Android and iOS platform is no way near stopping so let’s take this whole situation a step forward. By finding out which of these is the most secure platform for mobile app development in the year 2019.

Mobile App Development on Android Platform

As you might already be aware of, Android is the operating system that is currently leading the OS market share for mobile applications. This translates to the fact that there are hundreds and thousands of people that own an Android smartphone and also use android mobile applications in their day-to-day lives.

It all comes down to a major concern for securing the data of these millions of end-users and protecting their private information as well. Because mobile app security is crucial and cannot be messed around as it can the user lost its trust from the app as well as the platform. ���

With releases of the latest releases of OS update versions like Android Oreo and Android P, Android can be seen to learn from its previous mistakes and catch up with iOS. Keep on reading to know what changes have been bought by Google in Android.

Mobile App Development on iOS Platform

As we are proceeding towards 2019, many experts from the field of mobile app development have referred to ‘Mobile App Security’ as the hot topic of the year. With each day passing, companies are coming forward with innovative software and advanced tools to somehow tame this whole user security situation.

That’s exactly what Apple has been working on as well, although the iOS platform is considered to be one of the most secure mobile operating systems that exist today. But with the high increase in the usage frequency of mobile applications, more risks are now surfacing to the user’s private data. ��

The iOS platform can be referred to as a closed system because of all the restrictions imposed on it by Apple itself. But that does not mean that there is no reason to worry about the security aspects of developing an iPhone application.

Security Factors: Android vs iOS

Let’s have a look at some of the most essential security factors that are to be considered while developing a mobile application on an iOS or Android platform: ��


Encryption is a great method to ensure that your data is safe from various security breaches. Basically, by encrypting the user’s personal information the data becomes protected. On Android, you get the option of using an encrypted file system that will be encrypting the whole program of the app. By doing this, you can make sure that an individual’s data cannot be accessed by any other user of the application.

Apple uses the concept of Keychains to make their iOS apps more secure for the end-users here; the keychain is a password management system where each app has a different keychain attached to it for access. Mainly, Core Data is preferred to be used for security

measures as it is Apple’s persistence framework integrated with the SQLite database. By using the feature of ‘Data Protection’ the process of encryption is initiated.


The step of authentication in a mobile app can either make or break the security concerns. The process of authentication can be done via embedded login screens in iOS applications. While these embedded lock screens are not something that is new in the market, this method allows the user to have seamless integration with the mobile app. Extra switching delays are also resolved by using these lock screens.

The Android industry standard of dealing with authentication of external 3rd party services is by implementing the OAuth2 protocol on the mobile app. Using OAuth2 has several advantages like handling errors, authenticating an online service, getting permission to access an online service etc. A great example of this method is Google Services.

Tips for Building a Secure Mobile App

Below are a few important tips on how to build a secure mobile application:


  1. APIs plays a very crucial role in back-end programming of the app, so it is important to be careful with them as they can also turn out to be a security vulnerability. To avoid it from becoming a security concern only use the APIs that are verified for the platform that you are using i.e. Android and iOS.
  2. Securing data transmission is another tip that can come in handy while developing a mobile application. By using TLS, SSL (Secure Sockets Layer), and VPNs you can easily secure your information in transit between the sender and receiver by encrypting the data. Once the transmitting data is secure, it won’t be intercepted by an external entity easily.
  3. You can also eliminate the number of attack vectors by minimizing permission while developing your mobile application. The reason behind it is that zero-trust security is an emerging security method that only offers the minimal permission required by the user or the device itself. This ultimately reduces the chances of facing a security breach by the app.


Even though Android Application Development is preferred for developing a mobile app in case you are targeting a large audience base. But looking from the perspective of security iOS is the choice, the process of iOS app development is comparatively costly and time-consuming than the Android development process.

Yes, Android has been making significant improvements in its operating system updates but it still has a long way to go. But for the upcoming year, the title of the most secure platform for mobile app development goes to iOS.
