Deutscher Nutzer hier :)

Hab die App über Reddit gefunden und mal ausprobiert, funktioniert echt gut und macht Spaß. Sie hilft spielerisch in der heutigen Zeit zu erkennen was wirklich News, Übertreibungen oder sowas sind. Oder wenn man versucht unseren Verstand mit Methode XYZ zu beeinflussen.

Man wird halt auf den ein oder anderen Mind-Trick vorbereitet.

Ich find die App cool und lass mal 5* da.

Grateful this app exists

Mostly this app is great. The games are straightforward and get you practicing your logical fallacy spotting skills immediately. My only criticism is that some of the examples in the “people you meet” category feel AI generated or the writing is just really clunky and awkward. Maybe it’s meant to be vague so that it doesn’t seem to political but the vague robotic language is unnecessarily confusing.

Response from developer

This is useful and specific — thank you. You're right that some of the "people you meet" scenarios read stiffly, and the vagueness meant to keep them apolitical has made a few of them genuinely confusing instead. We're going back through that category. — the Fallacy team

Critical in this era

Such a useful app and essential life training. Highly recommended!

Response from developer

Thank you — "essential life training" is a high bar, and we'll keep trying to earn it. — the Fallacy team
