A mobile application is a software program built specifically for use on smartphones and tablets, optimised for the particularities of mobile devices, touchscreens, smaller screens, limited hardware resources and use while on the move. Unlike desktop programs designed for computers with a keyboard and mouse, mobile apps make use of device capabilities such as GPS, the camera, the microphone, the accelerometer and biometric sensors to deliver a personalised, context-aware experience. Mobile applications today cover almost every aspect of daily life, from communication, entertainment and education to banking, health, productivity and e-commerce, and have become the primary way users interact with digital services. Prolink builds mobile applications for companies across the EU who want exactly this kind of communication channel with their customers, from straightforward native builds to more complex cross-platform apps tailored to specific business processes, at development costs that reflect Central European rates rather than Western European agency pricing.
Types of mobile applications
Mobile applications fall into several categories depending on how they're built and the technology behind them. Native apps are developed specifically for one platform, iOS or Android, using the programming languages and tools optimised for that platform. iOS native apps are written in Swift or Objective-C, while Android native apps are built in Kotlin or Java. This approach delivers the best performance and the deepest integration with the device's operating system and hardware, but it requires separate development teams and higher costs if both platforms are targeted at once. Cross-platform apps are built once and run on both platforms through frameworks such as React Native or Flutter, which share a significant portion of code between the iOS and Android versions. Web apps are optimised websites that behave similarly to native apps inside a mobile browser, they don't require installation, but they have limited access to a device's hardware capabilities. Progressive Web Apps are an enhanced version of web apps that can work offline and can be added to a device's home screen, bridging the gap between web and native experiences. Depending on the pricing model, apps can be free, paid, or offer a freemium model with a free base version and paid premium features, plus in-app purchases for additional content or subscriptions. Prolink builds both native and cross-platform apps, depending on what a given project actually requires, so the choice of technology follows the client's real needs rather than a single fixed approach applied to every project. A more detailed overview of this approach is available on the page mobile application development.
Installing mobile applications on Android devices
Android is the most widely used mobile operating system in the world, present on devices from numerous manufacturers, Samsung, Google, Xiaomi, Huawei, OnePlus and many others. The Google Play Store is the primary and safest source for downloading apps on Android devices, holding more than three million apps and applying a review process that filters out malicious software.
- Open the Google Play Store on your device.
- Type the name of the app into the search bar.
- Review the results, paying attention to the publisher's name, rating, number of downloads and user reviews.
- Tap the Install button to start the download and installation.
- Wait for the process to finish, depending on the app's size and your connection speed, this can take anywhere from a few seconds to a few minutes.
- The app icon will appear on the home screen or in the app drawer.
- Tap the icon to launch the app.
- On first launch, some apps will ask for permission to access device features, only approve the ones that make sense for the app's purpose.
Installing apps outside the Google Play Store via APK files is technically possible, but isn't recommended for the average user, since it bypasses security checks and increases the risk of installing malicious software.
Installing mobile applications on iOS devices
iOS is an operating system exclusive to Apple devices, the iPhone and iPad, and is characterised by significantly tighter control over software installation compared to Android. Apps are available exclusively through the Apple App Store, a more closed ecosystem, but a considerably safer one, since every app goes through Apple's manual review process before becoming available to users.
- Open the App Store on your device.
- Type the name of the app you want into the search field.
- Review the results, the App Store displays screenshots, a description, ratings, reviews, developer information and a privacy policy.
- Tap the Get button for free apps, or the price button for paid ones.
- Confirm the download by entering your Apple ID password, or using Face ID or Touch ID.
- Wait for the download and installation to finish.
- The app icon appears automatically on the home screen.
- Tap the icon to launch the app.
Apple lets users enable automatic app updates in settings, which ensures all installed apps always run the latest version without manual updating.
Why regular app updates matter
Updating installed apps is one of the most important, yet most commonly neglected, habits of responsible mobile device use. Development teams regularly release updates that fix discovered bugs, close security vulnerabilities, optimise performance and introduce new features that improve the user experience. Security vulnerabilities are a particularly important category, outdated app versions can become targets for attacks that exploit known flaws for which newer versions have already released patches. On Android, updates can be set to download and install automatically over Wi-Fi, or triggered manually through the My apps option in the Google Play Store. On iOS, automatic updates can be enabled in Settings under the App Store option, with manual updates available through the Updates tab in the App Store. Neglecting updates can lead to weaker performance, incompatibility with newer operating system versions, security threats and loss of access to certain online services that require a minimum app version.
Security and responsible use of mobile applications
Mobile app security is a topic that grows more important as apps gain access to an ever larger amount of personal data, location, contacts, financial information, health data and private communications. A few basic principles help users stay safe. Only download apps from official stores, the Google Play Store or the Apple App Store, since both platforms run review processes that filter out malicious software. Carefully review the permissions an app requests, if a flashlight app asks for access to contacts or location, that's a red flag suggesting potentially malicious behaviour. Read the privacy policy of the apps you use, especially ones that handle sensitive personal data. Regularly review your list of installed apps and remove ones you no longer use, since unused apps with granted permissions can still pose a security risk. Use two-factor authentication where available, and never share login credentials across different apps or platforms. The same security principles that apply to users apply to development too, Prolink builds security standards, authentication and data protection into every project from the start, rather than adding them later as a patch.
Mobile applications as a foundation for digital business
For companies considering building their own mobile app, understanding the distribution and installation ecosystem is essential to making informed decisions about platforms, development technology and user experience. The choice between native development for one or both platforms and a cross-platform approach depends on the target audience, budget, timeline and the specific functionality the app needs to support, and that decision, made at the start of a project, has long-term consequences for maintenance costs and the ability to add new features later. Being present in the Google Play Store and Apple App Store means going through review and approval processes that can take anywhere from a few hours to a few weeks and require compliance with each platform's rules, and Prolink guides clients through that entire process, from the first specification through to launch in the stores, so those formal requirements don't slow the launch down.
A well-built mobile app that's properly optimised, secure and regularly updated becomes a lasting communication channel with customers and a powerful tool for building loyalty and business growth. Prolink builds mobile apps for a range of industries, from taxi and logistics to service booking and internal team tools, always starting from a concrete business goal rather than a generic template adapted after the fact.
