A web app is software that you can easily run in a web browser on your computer, phone, or tablet. It is completely independent of the user's operating system. Unlike desktop applications, you don't have to install or update anything. Unlike websites, the app is much more complex, it can work with databases, handle complex tasks, let third-party software access it, and much more.
A web application should always automate a process or solve a specific problem.
✅ Invoicing and accounting
✅ Reservation systems
✅ Connection to ERP
✅ Statement of work
✅ Information for customers (SMS, email)
✅ Assigning tasks
✅ Connection to payment gateways
✅ Creation and automation of offers
✅ Connection to warehouse management
✅ Recording of received customer requests
✅ Automatic notifications (SMS, email, etc.)
You can update and "release" a web application several times a day. The latest version is always available to users of the app. This makes the web app more flexible and secure than, for example, desktop or mobile apps.
The web application is accessible from anywhere and at any time. Just own a device with any web browser.
Web applications run on powerful servers that can handle demanding functions much more efficiently. They don't put a strain on your computer or mobile phone.
