QLab

Die App ist eine digitale Erweiterung des „QuantumSchoolLab“ an der Universität Duisburg-Essen. Mithilfe von Augmented Reality wird das Verständnis für die komplexen Versuche erleichtert. So kann man z.B Photonen während eines Quantumschlüsselaustauschs verfolgen und erhält so ein besseres Verständnis für die inhärente kryptographische Sicherheit des Schlüsselaustauschs. Mithilfe der AR-App gelingt es das normalerweise Unsichtbare sichtbar zu machen. Bisherige Inhalte: Aufbau und Funktionsweise des Quantumschlüsselaustauschs und des Quantenradierers. Die Inhalte der App werden nach und nach erweitert. Voraussetzung für die Nutzung der App ist ein Besuch im Schülerlabor oder die auf der Website zur Verfügung gestellten Materialien.

Verdict
The clearest difference is iOS requirement: QLab at 13.0 against CASSY App's 15.0. On price, ads, in-app purchases and device support there is nothing between them.
