Quantum Mechanics + vs qFt
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Quantum Mechanics +
Explore quantum physics by numerically solving the Schrodinger Wave Equation. Visualize bound states and wave packets with various potentials, ideal for educational demonstrations. Accurately calculate energy values and observe quantum phenomena like tunneling.
- Solve Schrodinger's Wave Equation
- Visualize bound states and wave packets
- Simulate various potentials (Harmonic Oscillator, Square Well, etc.)
- Observe quantum phenomena (Ramsauer-Townsend effect, tunneling)
- Accurate energy value calculation
- Educational tool for introductory courses

Numerically solve Schrodinger's Wave Equation with various potentials for bound states and wave packets. Real Quantum Physics - suitable for a theory lab or demonstration in an introductory Quantum Mechanics course. Find bound states for Harmonic Oscillator, Square Well, Ammonia Maser, Hydrogen Atom, and Delta Function Potentials. Follow a wave packet as it hits a Step Barrier, Resonant Potential and Tunnel Barrier. Enter energy values for a bound state and see if the solution converges - real energy values accurate to better than 1%. Observe the Ramsauer-Townsend effect and a wave packet tunnel through a forbidden potential barrier.

Verdict
The clearest difference is in-app purchases: qFt at none against Quantum Mechanics +'s 1. Quantum Mechanics +'s advantage is iOS requirement (13.0 vs 16.0). On price, ads and device support there is nothing between them.
