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 ฮฑ/ฮฒ state readouts in multiple forms Smooth camera controls and polished visual modes Great for students and educators

Verdict
The clearest difference is in-app purchases: BitSpinner at none against Shor's algorithm's 3. Shor's algorithm's advantage is iOS requirement (16.0 vs 26.0). On price, update cadence, ads and device support there is nothing between them.
