How Felgo helps Qt Developers & Engineers to succeed

The Challenge

Killisperger is a reseller of heating oil and freight forwarder. Their goal was to provide an app for Android, iOS, and Windows featuring a clear overview of their products & services as well as the option to buy and schedule deliveries for businesses as well as private customers.

The Solution

A cross-platform framework had to be the basis, the team already had experience with Qt. However, they realized that Qt is missing many components and coding those themselves would have taken a lot of time and effort. The Felgo tooling provided simple solutions to alleviate the time constraints: features like QML Hot Reload, ready-made plugins (i.e. Firebase) & out-of-the-box UI/UX components supporting all target platforms made development extremely easy and fast. In addition, the option to get help from the Felgo professional services team at any time made rapid adoption and maximum efficiency in utilizing the tooling possible.

The Outcome

Version 1.0 was released on Android and iOS within 2 months instead of 4. On top of that, the final app exceeded the planned results: significantly more features were implemented.

What our Customers Say


If I only knew about Felgo before! It would have saved us about 50% of the development time compared to plain Qt, and we would have been able to focus on the app itself, instead of recreating problem solutions that are already provided by Felgo, and that are not unique or specific for our app.

So, please: Don’t make the same mistakes, use Felgo! Just as we will, from now on.
