Die GSAapp basiert auf dem Datenbestand des ChemInfo-Systems, welches durch ein Bund-Länder-Kooperationsprojekt betrieben und gepflegt wird. In der GSAapp können mittels unterschiedlicher Profile für Feuerwehr, Fachberater, Rettungsdienst und THW intuitiv Informationen von etwa 40 000 Stoffen überprüft werden. Die GSAapp bekommen Sie mit einem Demodatenbestand. Damit werden die Funktionen der GSAapp verdeutlicht. Wenn Sie berechtigter Nutzer von ChemInfo sind, können Sie kostenlos den kompletten Datenbestand der Gefahrstoffschnellauskunft herunterladen. Eine kostenfreie Registrierung für Behördenmitarbeiter und Einsatzkräfte ist hier möglich: http://www.chemikalieninfo.de/gsaapp.htm Die GSAapp ist unterteilt in eine Stoff- und Transportsuche. Mit der Transportsuche kann mittels Eingabe von Suchparametern in eine visualisierte Warntafel nach rechtlichen Regelungen und Gefahren von Transportgütern im Allgemeinen gesucht werden. Über die Textsuche können chemische Eigenschaften zu einzelnen Stoffen recherchiert werden. Zur Eingabe und Suche dienen Stoffnamen, CAS-Nummern oder UN-Nummern. Je nach eingestelltem Profil werden die gefundenen Informationen aufbereitet in unterschiedlichen Tabs angezeigt. Enthaltene Informationen sind u.a. allgemeine Stoffeigenschaften, Gefahren und Maßnahmen sowie Schutz- und Erste-Hilfe-Hinweise.

Verdict

The call

The clearest difference is review sentiment: QROX at 68% against GSA's 6%. QROX also leads on update cadence (every 5 weeks vs every 6 months). GSA's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases, device support and iOS requirement there is nothing between them.
