Company
Sick App Developers GmbH
A German software company that builds, publishes and operates its own mobile apps and web products.
What we do
Sick App Developers GmbH develops and operates software products — mainly mobile apps, together with the web and backend systems they depend on. We publish our apps ourselves, so we are responsible for them from the first release to the last update.
Alongside our own products, we are building a new line of business in B2B software discovery: helping businesses choose software and partnering transparently with the vendors behind it.
-
Build
We develop mobile apps, primarily with Flutter, together with the web and cloud services behind them.

Operate
After launch we handle updates, support requests, data-protection questions and account deletion ourselves.
-
Learn
We test distribution channels for our products and carry what works into new projects.
