Web Application Development FAQ

What is a web application?

A web application is software that runs in a browser, such as a customer portal, configurator or dashboard. Users don’t need to install it, and it works on desktop and mobile.

How much does web application development cost?

At SPLIT Development, web app development is billed from $35 per hour. You get an estimate after a free review and a clickable prototype.

How long does it take to build a web app?

Timing depends on features, user roles and integrations. Apps are built in stages, so a first version can launch before the full feature list is done.

Can a web app connect to my Shopify store?

Yes. Web apps can use Shopify’s APIs to read products, create orders and update customers, like the configurator and AI design tools SPLIT Development built for Nuvisso and Artificial Printer.

Web app or mobile app: which should I build?

A web app works on any device through a browser and needs no app store release. A mobile app fits when you need deep device features. A progressive web app sits in between.

Who owns the code?

You do. Code, designs and accounts created for your project belong to you, and you get full access at handover.
