BitSpinner
Read full descriptionHide full description
Spinner makes quantum intuition visual, interactive, and fun. Explore a live Bloch sphere, drag to rotate and pan, and apply quantum gates instantly to see how a qubit evolves in real time. Spinner shows both geometric motion and state notation side by side, so you can connect what you see to what the math means. Built for iPhone and iPad, Spinner combines a clean control surface with a moody, immersive 3D scene to help you learn, teach, and experiment. Real-time Bloch sphere interaction Instant gate application (X, Y, Z, H, S, T, and more) Live α/β state readouts in multiple forms Smooth camera controls and polished visual modes Great for students and educators
QuantumKamil

QuantumKamil makes elementary-particle mass visible: on screen, bigger means heavier. Explore quarks, leptons, bosons and the Higgs on a logarithmic scale (plus three linear windows), with 3D visuals inspired by Kamill Laurent’s work: charge ball, spin shell, QCD colors. Features: • Navigable scene (Studio, Chalkboard, High contrast) • Tap = select, double tap = fact sheet with mass, charge, spin and “why it looks big/small” • Rebuild mass with Kamill’s log formula • Italian and English interface Built for students and teachers of Standard Model physics. Attribution and links to the original video/GitHub are included in the app.

Verdict
The clearest difference is update cadence: QuantumKamil at every 2 days against BitSpinner's every 4 months. QuantumKamil also leads on iOS requirement (17.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
