Funktioniert nicht

Sonst 5 Sterne, aber unter iOS 26 stürzt die App beim starten ab und funktioniert dementsprechend überhaupt nicht mehr :(

used for years now

love this app, but as of recently haven’t been able to view anything other than the drug list… can’t search and can’t see any drug reports, would love for this feature to be added back as it helped a lot to identify things i had myself

Amazing app!

I love everything about this app—it looks very sleek, and is extremely helpful/informative. It’d be cool to see W-18 on here though!

una app necesaria

como dice en otra reseña, la gente no va a dejar de consumir, siempre habrá gente que consuma drogas y es mejor saber que llevan para prevenir malos viajes/sobredosis o muerte. Es bueno tener información.
