SQQuantum Studio: The Universe in Your Hands Welcome to SQQuantum by Sapiens Qualia—a breathtaking leap in mobile scientific computing. SQQuantum bridges the gap between high-end desktop tensor analysis and accessible mobile education, putting a fully functional, lightning-fast quantum circuit simulator directly onto your iPhone and iPad. Whether you are a university physics student learning the fundamental mechanics of entanglement, a software engineer transitioning into quantum logic, or a researcher testing state-vector mathematics on the go, SQQuantum provides a flawless, professional-grade Integrated Development Environment (IDE) optimized specifically for the Apple ecosystem. OPTIMIZED FOR APPLE SILICON SQQuantum is an engineering masterpiece. Under the hood, it is powered by a custom-written, native C++ state-vector engine utilizing the heavy-duty Eigen mathematical framework. By bridging Swift directly to C++ and compiling natively for Apple’s A-Series and M-Series processors, the app achieves zero-latency, real-time matrix multiplications entirely offline. It natively projects complex quantum physics calculations onto a beautifully fluid, hardware-accelerated SwiftUI canvas without dropping a single frame. POWERFUL FUNCTIONALITY • Dynamic Circuit Canvas: Build complex quantum circuits using multiple qubits. Apply fundamental quantum logic gates including Hadamard (H), Pauli (X, Y, Z), Parametric Phase Shifts (Rx), Controlled-NOT (CX), and Measurement operations. • Interactive 3D Bloch Sphere: Visualize the invisible. Utilizing Apple’s native SceneKit framework, our 3D projector allows you to touch, drag, and rotate the Bloch sphere to intuitively understand qubit vector phases and superpositions in real-time. • Live Probability Distributions: As you build your circuit or drag parameters, the simulator instantly calculates the wave function and renders the exact probability distribution of your quantum states in a vibrant, responsive UI. • Hardware Noise Simulation (NISQ): Experience the reality of modern hardware. Use the dynamic noise slider to inject probabilistic decoherence and environmental noise into your gates, simulating how physical quantum computers actually behave. • Live OpenQASM 3.0 Generation: SQQuantum acts as a true developer tool. As you visually construct your circuit, the app simultaneously compiles industry-standard OpenQASM 3.0 code in a dedicated terminal pane. Copy it with one tap to export and run your exact circuit on real IBM or AWS quantum mainframes. • Instant Entanglement: Instantly load complex quantum phenomena like the Bell State (Quantum Entanglement) and GHZ State with a single tap. PRO iPadOS ARCHITECTURE SQQuantum intelligently adapts to your hardware. On the iPhone, it provides a sleek, highly readable, vertically scrollable interface. On the iPad, the UI transforms into a gorgeous, split-pane professional IDE—featuring a sprawling mathematical workspace on the left, a dedicated hardware inspector on the right, and a full-width code terminal pinned to the bottom. 100% PRIVATE & OFFLINE Science requires focus, not tracking. SQQuantum is 100% offline. It requires zero account sign-ups, utilizes zero cloud processing, contains no advertisements, and collects absolutely zero user data. Your algorithms belong to you. Step into the mathematical fabric of the universe. Download SQQuantum Studio today and start building the future.
Braid Code

Braid Code is the mobile companion for Braid, the desktop app for running AI coding agents across multiple Git worktrees. Pair your iPhone or iPad with Braid on your Mac, then keep an eye on your coding sessions from anywhere on your local network. See which agents are running, which ones need input, and which tasks have finished. Open a worktree, inspect active terminal sessions, and jump back in when your attention is needed. Use Braid Code to: - Pair securely with your Braid desktop app using a QR code - View connected desktops, projects, worktrees, and agent status - Monitor Claude, Codex, Gemini CLI, and other terminal-based coding agents launched from Braid - Open terminal sessions linked to a worktree - Track recent activity and focus on agents that need input - Receive notifications when an agent finishes, errors, or waits for a response - Check connection diagnostics when your desktop is unreachable - Review usage and rate-limit status from supported providers Braid is built for developers who run several AI coding tasks in parallel. Instead of constantly returning to your Mac to check every terminal, Braid Code gives you a focused mobile view of the work that is active right now. Requirements: - Braid desktop app running on macOS - Your iPhone or iPad and Mac on the same local network for local connections - Camera access to scan the desktop pairing code - Notifications are optional and can be configured in Settings Braid Code does not replace the desktop development environment. It extends it, so you can monitor progress, respond at the right moment, and keep multiple agent sessions moving.
