Monium puts superconducting-qubit physics in your pocket — a mobile companion to the open-source scqubits library, built for researchers, students, and the quantum-curious. Pick a qubit, tune its parameters with live sliders, and watch the physics update in real time: • Energy spectrum vs. any swept parameter • Wavefunctions over the potential (and in the charge basis) • Matrix elements as a heatmap, and vs. the swept parameter • T1 / T2 coherence times per noise channel • Exact computed values behind every plot, as tables Supported qubits: Transmon, Tunable Transmon (SQUID), and Fluxonium. Built for real work: • Enter the Josephson energy the way you measure it — critical current, junction inductance, or room-temperature normal-state resistance (with a cryo/room ratio). • Save and reload presets per qubit. • Convergence indicators so you can trust the numbers. Everything runs on-device. No account, no ads, no tracking, no network — your work stays on your phone. Monium mirrors scqubits' conventions and is validated against it, so the numbers match the desktop tool you already trust.

Verdict

The call

The clearest difference is price: Quantum Computing at Free against Monium's $3.99. Quantum Computing also leads on device support (4 vs 2). Monium's advantage is in-app purchases (none vs 1) and iOS requirement (15.1 vs 17.0). On ads there is nothing between them.
