Benefits of the mobile app
We recommend developing a mobile app for cases where you need a particularly user-friendly interface and business process integration. Most of the goals that a mobile app achieves can be achieved by the web-based version of the system, but it is often slower and cannot work without an internet connection. Developing apps allows time and other business resources to be maximised to optimise business processes.
The main objective of the mobile app is to improve the daily processes of employees and users through smart devices.
Mobile app development process
Developing a mobile app always starts with an app description. The development team needs to know what your business needs and what design would suit you. Then, knowing all the necessary features, the team will prepare a time and financial estimate. These are agreed with the client, and once confirmed, we get to work to bring tangible benefits to your business as soon as possible. Once the work is complete, the app is uploaded to the App Store.
Server-side is an important part of application development
Developing mobile apps requires an additional application on the server that acts like a brain - doing calculations, storing data, logging changes made to the system and more. We use PHP programming language and Laravel framework to develop the server-side application. The development of the server application is included in the price of the mobile app development.
A mobile app development success story
Mobile app development has helped many of our clients. Our favourite example is auditing equipment in a manufacturing company. We developed a mobile app that only allows auditing when the user scans a QR code for the employee and the device that changes daily. This ensures that the auditing process is fully compliant and that the employee must be in the vicinity of the equipment in order to audit it.
Technologies used to develop mobile apps
As we want to make mobile apps available to as many employees as possible, we use React Native technology, which allows us to create apps for Android and iOS devices.
Notas IT teams have experience in mobile app development
Mobile apps are an area we've been working on since 2019. During this time, we've managed to complete many projects and gain invaluable experience. We have developed both public and business-only mobile apps.
Mobile app design
We have a network of trusted partners who create designs tailored to individual business needs. We'll make sure your mobile app development is implemented from A to Z - starting with an idea, a detailed analysis will be carried out, which will lead to the creation of an app that optimises your business processes.
Mobile app testing process
Mobile app development is unthinkable without detailed testing. The first testing is done on emulators, but we also have Apple and Android devices of various sizes and manufacturers, on which we try to use the app as a real user. The team's experience in mobile apps and testing allows us to efficiently find and fix bugs faster than users can access them. We have real iOS and Android devices that allow us to test apps under real conditions.
Maintenance, development and design services for developed applications
With changing consumer habits and the ever-increasing variety of technologies, changes to the app are inevitable. We are happy to expand your mobile apps and their functionality.
Cost of app development
Developing a mobile app is a bespoke process that requires detailed analysis and knowledge of business processes. Typical app development project costs start from €3200 + VAT.
