Q

Read full description

Q-Bridge is a quantum job workbench for iPhone, iPad and Mac, for developers and researchers who write quantum circuits, submit them and want to follow the results in one place. WHAT YOU CAN DO β€’ Run a circuit β€” Paste OpenQASM (the Bell circuit is already filled in), tap Run and see the counts on the same screen. The editor is on every plan. β€’ Follow every job live β€” Each job moves from queued to running to completed on screen, and the list updates the moment a status changes. β€’ Your provider jobs, read-only β€” Jobs β€Ί Provider jobs lists up to 20 recent jobs from your own IBM Quantum or Amazon Braket account: status, the provider's status, backend, created time, and measurement counts once a job finishes. Nothing is submitted, cancelled or deleted. Your key stays in the device Keychain on iPhone, iPad and Mac, never on Q-Bridge servers. Every plan. β€’ Emergency stop β€” One tap cancels all of your active jobs, and the app shows which jobs, if any, could not be stopped. β€’ Open real results β€” Finished simulator jobs return measurement counts, with the job's history and details. β€’ Cloud simulator β€” Circuits run on our noiseless cloud simulator, not on your device. The qubit limit depends on your plan. β€’ Compare backends from seven providers (Pro) β€” Browse backends from IBM Quantum, IonQ, Rigetti, Quantinuum, PASQAL, QuEra and Amazon Braket side by side in one catalog. β€’ Bring your own provider credentials β€” Provider API keys you add stay in your device's Keychain; none is bundled, and the simulator needs none. They are sent only with requests that need them: reading your provider jobs, or the catalog and jobs you submit to a provider (Pro). β€’ Backend suggestions on your device (Pro) β€” On supported devices, Bridge Advisor suggests a backend with Apple's on-device model; your circuit is not sent anywhere for it. β€’ Bloch sphere β€” Visualize single-qubit states interactively, on every plan. β€’ Easy start β€” A short intro you can skip or replay from Settings, and a guest mode before you create an account. BUILT FOR APPLE PLATFORMS A native app for iPhone, iPad and Mac, with Liquid Glass design. Universal Purchase: one subscription covers iPhone, iPad and Mac. Available in English, Korean, Japanese, Simplified Chinese, Spanish, French and German. PRIVACY No ads and no third-party tracking. The camera is used only when you choose to scan a QR code to pair a gateway. Provider keys stay in the Keychain. Creating an account requires you to be 13 or older. PLANS β€’ Free β€” Cloud simulator jobs (8 qubits) with live tracking, the OpenQASM editor, read-only Provider jobs, emergency stop and the Bloch sphere. Without an account: 3 runs a day. β€’ Pro β€” $24.99/month or $159.99/year. Adds 20 simulator qubits, the seven-provider catalog with your own credentials, Bridge Advisor and more tools. β€’ Team β€” $69.99/month or $549.99/year. Everything in Pro, plus the Team workspace and Team tools. β€’ Enterprise β€” Contact sales. Not sold in the app. β€’ Job submissions per day: Free 100 Β· Pro 1,000 Β· Team 5,000. You can subscribe without creating an account. Prices shown are in US dollars; your local App Store price may differ. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in your Apple Account settings. Payment is charged to your Apple Account.

Digger DNS lookup

Features
Read full description

Digger is a DNS lookup tool for iPhone. Enter a name, pick a record type, and inspect the full current Resultβ€”without uploading your queries. It talks DNS directly. It does not run the dig command. Switch between a structured view and generated dig-style text, then copy or share the view you are looking at. Query A, AAAA, CNAME, MX, TXT, NS, SOA, PTR, SRV, CAA, HTTPS, and SVCB. Use the system resolver or a custom server. Choose automatic, UDP, or TCP. EDNS is on by default; the DO bit is optional. Cancel a Query in flight. Results include the response code, flags, all four sections, timing, and wire size. NXDOMAIN and SERVFAIL are DNS Results, not crashes. Digger does not validate DNSSEC. Privacy: Query data is not uploaded. Results are discarded when you leave them. Recent Queries stay on this device as name + type only. Clear History anytime in Settings. Digger is not a VPN or device-wide DNS changer. No DoH, DoT, or zone transfers.
