About

Electric Field Explorer

Features
Read full description

E-Field Explorer makes electric fields visible and intuitive. Place positive and negative charges directly on the field, move them freely, and watch field lines, equipotential lines, and field strength update in real time. Use preset scenes such as a single charge, dipole, quadrupole, capacitor, or hollow sphere for a quick start, then adapt each setup to your own experiment. You can adjust charge strength for selected charges and optionally show labels for clearer orientation. The integrated particle emitter makes field behavior especially easy to grasp. Choose positive or negative test charges, automatic emission or single pulses, and damped or undamped motion. That makes the app ideal for teaching, self-study, and visual demonstrations on iPhone and iPad. Features: - Place positive and negative charges with drag and drop - Toggle field lines, equipotential lines, and heatmap - Adjust the strength of individual charges - Start from preset scenes for common electrostatic setups - Share screenshots directly from the app

About

QLab

Read full description

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 call

The clearest difference is price: QLab at Free against Electric Field Explorer's $1.99. QLab also leads on iOS requirement (13.0 vs 26.0). On ads, in-app purchases and device support there is nothing between them.
