Design, run and understand quantum circuits on iPhone, iPad and Mac. SwiftQuantum is a native quantum circuit IDE for students, researchers and developers. Build a circuit, run it, and see what it does β with clear rules about where your work goes. BUILD CIRCUITS YOUR WAY β’ Drag-and-drop editor with the standard gates: H, X, Y, Z, S, T, rotations, CNOT, CZ, SWAP, Toffoli and more β’ Start from ready-made circuits such as Bell and GHZ states β’ See measurement probabilities for every run RUN ON YOUR DEVICE β’ Free plan: the Standard engine runs circuits up to 10 qubits on your device β’ Paid plans: Turbo and HyperCore engines simulate general circuits up to 25 qubits on your device β’ Every engine computes exactly the circuit you drew, in shot mode too β’ On Team and Enterprise, Clifford (stabilizer) circuits up to 127 qubits run on your device β tested on a real iPhone in airplane mode β’ A circuit goes to our server only when it needs it (more than 25 qubits with non-Clifford gates), and only after you tap Send β’ Benchmark (Home > Quick Actions, when signed in): median run time per engine with a 95% confidence interval, measured on your device AI THAT STAYS ON YOUR DEVICE β’ Optional: download a compact AI model once, describe a circuit in plain language, and get a circuit back β generated with no network β’ Your prompts stay on your device β’ Accepted results are sealed into a local, tamper-evident record you can check in Settings. A seal shows the generation happened on your device; it does not guarantee the circuit is correct β’ Off by default; delete the model whenever you like ERROR CORRECTION (TEAM AND ENTERPRISE) β’ Run surface-code experiments on our engine: choose the code distance, physical error rate and decoder β’ See the logical error rate from Monte Carlo shots with a 95% confidence interval β’ The error rate chart says where each curve comes from: measured on our engine, measured on your device (distance 3, offline), or a dashed reference formula TAKE YOUR WORK WITH YOU β’ Import and export OpenQASM; on Team and Enterprise, also convert circuits to PennyLane and CUDA-Q code β each conversion shows its measured state overlap with your circuit, or βNot verifiedβ β’ Paid plans: inspect a circuit's unitary matrix; Team and Enterprise also compare gate fidelity KEEP A RECORD OF WHAT YOU RAN β’ Q-Footprints: an opt-in practice log of the simulations you run on your device β’ Your circuit itself is never sent β only the shape of the run β’ A seal shows a run happened; it is not a skill score or a certification BUILT FOR THE WAY YOU WORK β’ Native on iPhone, iPad and Mac β’ Available in 7 languages β’ Free to start Who it's for: students learning quantum computing by doing, educators teaching with real circuits, and developers prototyping quantum programs. β SwiftQuantum is free to download with optional auto-renewable subscriptions. Payment is charged to your Apple ID at confirmation of purchase and renews automatically unless cancelled at least 24 hours before the end of the current period.

Verdict
The clearest difference is iOS requirement: DevTools+ at 15.1 against SwiftQuantum's 18.0. On price, update cadence, ads and in-app purchases there is nothing between them.
