Why order Apple iOS application dev outsourcing?


Benefits of iOS mobile outsourcing

Users of Apple devices are considered the most solvent, which is confirmed by statistics. In addition, users of Apple devices know quite well that the App Store publishes only verified, reliable and high-quality software, and therefore, they are more willing to install, use and invest money in iOS apps.


Facts about iOS apps

In 2021, the App Store featured over a million gaming apps and 3.74 million non-gaming apps. Every second, users download from the store about 850 games and programs for iPad, iPhone and iPad. * Since the inception of the Apple App Store, mobile app developers have earned about $ 30 billion.*

Features of iOS apps development outsourcing

Interface features

During  iOS app outsourcing, it is necessary to take into account certain features and requirements: the absence of a “Back” button on the devices, the app working on both iPhones and iPads and different options of side and resolution ratios. Also, the developers should not forget about the signature line of the iPhone, starting with X version, the famous “bangs” –  a part of the device screen, where the front camera and sensors are located. The design should be suitable for devices with and without this element. And most importantly, the recommendations and requirements of the corporation Apple – Human Interface Guidelines – should be observed in iOS app development.

Development for iOS: native design

IOS outsourced development meets Apple requirements. When developing an application, you must use your own interface templates. This allows the user to quickly understand the interface and find the functions they need. Our iOS outsourcing company creates animations that aid navigation and give your app experience a unique character.

Publication of iOS app

Publishing an app requires adherence to the strict Apple guidelines. Throughout the app review phase, our developers are guided by moderators to ensure that the app would be published. iOS software development ends with release. The team then takes part in improving and updating the application.

Updating the iOS apps

With the release of each new device and the OS update, the vast majority of mobile apps need to be adapted to new conditions. App Store statistics shows that users of iPhones willingly update to the current OS version. Therefore, the apps should meet current requirements. For example, an app should support the dark mode introduced in the devices in 2019.


The iOS operating system was released by Apple in 2007. Until 2019, both iPhone and iPad ran on it, but now this has changed with the recent development of separate operating systems for iPad. In this article, we will discuss the platform features and development of mobile apps specifically for iPhones.

Peculiarities of iOS mobile apps

The first and the main distinctive feature of iOS apps is that the fleet of devices is much smaller than the number of smartphones with Android. This means the adaptation of the mobile app appearance for iPhones currently presented in the market is easier.

Thus, screens of modern iOS devices have a good resolution. This allows using thin fonts. They are not distorted, as happens on displays of poor quality.

The similar architecture of the devices allows users to avoid additional checks when starting the app. There is no need to check availability of a camera, a GPS sensor or an accelerometer.

Features of outsource iOS app development

And still, despite the fact that the range of devices running on iOS platform is much smaller than that of those running on Android, there are a lot of development peculiarities.

1. The developer has to consider not only the size of the screen, which is important in the application design, but also the hardware differences of each device. Using the features of the smartphone can greatly increase the user loyalty, which will lead to boosting the app’s rating in the store.

Whenever a new version of the operating system is released, most users update their devices  almost immediately. But the new version can be very different from the previous one, and some features of the app may not work properly or may not work at all.

2. Accordingly, the code should be kept up to date. Yet, Apple does not provide a complete list of all the new features in advance, giving access only to beta versions with incomplete sets of functions, the implementation of which may eventually differ. Therefore, within a few weeks after the release of the new OS final version, it is necessary to test the mobile app and quickly adapt it to the new conditions, if necessary.

3. Another block of the platform features is the design. The visual component always has been a priority for Apple, so the audience is used to stylish interfaces, intuitive app controls and obvious arrangement of sections. Moreover, strict guidelines must be followed to successfully pass the test before publishing the app in the App Store.

4. When developing a design, the developer should take into account that some users open the app in compatibility mode on tablets. On some iPad models, the resolution of the workspace becomes the same as the one of the old iPhone models: 4 and 4s. The Apple application check service often checks the apps intended for iPhone only on an iPad.

Apple’s policy on publishing the apps in the App Store

The App Store has strict requirements that must be met when releasing an app. It is important not only to comply with all the design guidelines, but also to ensure the confidentiality of user personal data, the app’s stability during the operation and, most importantly, its usefulness.

One of the reasons for having an app rejected can be that the verifier considers the app useless or not useful enough against the background of many similar apps in the App Store. In this case, the functions of the app should be revised. The app should be supplemented with the elements that affect the innovations of the operating system. Such apps are readily accepted, which encourages the developers to continue to support the latest features of the operating system.
