mobile app approaches

First a brief overview of the four approaches:

Native apps

A native app is a traditional way of making apps. Native apps are built with separate codebases to target different platforms (Apple iOS & Android). Because each platform has to be addressed separately, the development is very costly and requires broad technological expertise. On the other hand, native apps are the best way to benefit from the particular device features, resulting in unrivaled user experience.

Cross-platform apps

Unlike native apps, cross-platform apps share the same code base. The main difference is that they use a native rendering engine to compile the app for the different platforms. That’s why they’re also called Compiled to native apps. This provides close-to-native user experience and better performance compared to hybrid apps. They offer seamless functionality, relatively easy implementation, and cost-effective production. If you want to offer app functionality on a website as well, you will still have to maintain two codebases, since cross-platform apps are not based on web technologies.

Hybrid app

Hybrid apps blend web elements with mobile ones. They are built on a single codebase of standard web technologies (HTML, CSS, JavaScript) and are then wrapped inside a native container that provides (limited) access to hardware functionalities of several platforms. Because they are based on the same technologies, hybrid apps are particularly suitable if you want to offer functionality not only in an app but also as a (progressive) web application in a normal web browser.

Progressive web apps (PWA)

Progressive web apps (PWA) are basically normal websites which (if supported by the browser) behave almost like native apps and the longer the more they support functions that were previously only available in native or hybrid apps (e.g. offline mode, push notifications). In addition to the low development costs, the main advantage is that the app content can be found on the web via search engines, which is a decisive factor for e-commerce applications. All other app types can only be obtained via app stores. If the availability in app stores is an important requirement, a hybrid app can be developed based on a PWA with relatively little effort.

Each type of app has its pros and cons based on various factors such as functionality, technological know-how, findability of the content (target group), or budget. Objective and technology-agnostic, the ERNI AppType Chooser helps you to come to the right decision for your project. Just answer a handful of easy-to-understand questions about your planned app. By the way, the ERNI AppType Chooser itself was developed as a Progressive Web App (PWA), which allows easy home screen installation for mobile devices and (limited) offline availability.

    Recognising trends: An insight into regression analysis

    Data plays a very important role in every area of a company. When it comes to data, a distinction is made primarily between operational data and dispositive data. Operational data play an important role, especially in day-to-day business. However, they are not nearly as relevant as dispositive data. This is because these data are collected over a longer period of time and provide an initial insight into the history or the past.

    Why do we need digital transformation for medical devices?

    For hospitals, it is not up for discussion as to whether they want to digitalise. The increasing age of the population in western countries and the progressive shortage of medical professionals mean that without digitalisation, the healthcare system will not be able to provide the quality that patients want in the future.
