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 update cadence: Quantum Mechanics + at daily against Quantum's every 5 weeks. Quantum Mechanics + also leads on monetization model (free vs free with in-app purchases) and review sentiment (100% vs 81%). Quantum's advantage is ratings volume (150 vs 4). On price, rating, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Quantum Mechanics + sells 1 one-off in-app purchase and Quantum sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.8 for Quantum Mechanics + against 4.8 for Quantum. That said, the two scores are not equally well evidenced: Quantum has 150 ratings behind it against 4, so its average is the more settled of the two. Written reviews are what separate them: 100% of Quantum Mechanics +'s written reviews are positive against 81% of Quantum's.
Quantum Mechanics + ships an update daily, Quantum every 5 weeks. Both last shipped on October 24, 2026.
