SwiftQuantumDescribe a circuit and the app builds it.
A quantum IDE for iPhone, iPad and Mac. Describe a circuit in plain language and the app drafts it for you to edit, using Apple’s on-device model where available and a simpler rule-based drafter otherwise. Simulate up to 25 qubits, or 127 for Clifford circuits on higher plans.
Free plans run circuits on our cloud engine; paid plans can also simulate on your device.
How it works
Plain language → circuit
Say what you want to test. The app drafts the gates for you to inspect, edit and run. It also works from Siri Shortcuts.
The Lab: Bloch sphere, gates and live probabilities.
A Bloch sphere you can touch
Apply H, X, Y and Z, run the circuit, and see the resulting state and probabilities on the sphere.
More power on higher plans
Pro raises the limit to 25 qubits. Team and Enterprise add Clifford simulation up to 127 qubits and quantum error-correction decoding. Enterprise adds API keys.

Compare every product’s plansFrequently asked questions
Do I need to know quantum physics?
No. Describe what you want in plain language and inspect what gets built. If you want the theory, QuantumNative teaches it.
Is it really free to start?
Yes. Every app is a free download, and most have a free tier that never expires. On Q-Shield Sentinel, free accounts get a basic assessment; full audits start with the one-time Starter plan.
Can I cancel anytime?
Yes. App Store subscriptions are managed in your Apple ID settings; web subscriptions in your account. Cancel at least 24 hours before renewal and you will not be charged again.
Why do App Store and web prices differ?
Apple sets in-app prices per region and takes a commission; web checkout runs through Stripe. We show web prices here and the app always shows your exact in-app price before you confirm.
Where does my data go?
Paid plans run simulations on your device; free plans use our cloud engine, hosted on AWS in Seoul. AI tutor chats go to OpenAI in the apps and Anthropic on the web, without your name or email; QuantumCareer cover letters include the name on your profile. Deleting your account removes your sign-in data immediately (GDPR Art. 17). The Privacy Policy has the details.
