'Geprüft' (tested/tried) is the past participle of the verb 'prüfen' (to test/check). It is used like an adjective to describe that something or someone has undergone the action of being tested or tried.

The meaning of 'geprüft' (tested/tried) depends strongly on the context. If it refers to an object or thing, it is about a technical check. If it refers to a person, it usually means difficult life experiences.

In a technical context, 'geprüft' (tested) is often combined with the type of testing. Common compounds are 'qualitätsgeprüft' (quality-tested), 'sicherheitsgeprüft' (safety-tested), or 'TÜV-geprüft' (TÜV-tested).

controlled
'kontrolliert' and 'geprüft' can both mean that something has been looked at in order to find mistakes or problems. But they are not always the same. 'geprüft' emphasizes the result of an examination: something has been tested or checked for correctness, quality, or safety. 'kontrolliert' can also mean that something is monitored or regulated according to rules. Learners may confuse the words because both have to do with safety and control. When a test or a careful examination is the focus, 'geprüft' is often a better fit. When it is about monitoring or following rules, 'kontrolliert' sounds more natural.
