About this app

Master the 3×3 puzzle cube across Android XR headsets, foldable phones, tablets, and mobile devices! Cube Solver XR combines a fast step-by-step 3D solver, real-time camera color scanner, structured CFOP mastery curriculum, hands-free voice coach, and a WCA-style speedmat timer into one seamless spatial and 2D experience.

✨ BUILT FOR ANDROID XR, FOLDABLES, TABLETS & PHONES
• Full 3D Spatial Mode (Android XR): Interact with a floating 3D cube in your physical space, place a virtual speedmat on any table with physical two-hand contact tracking, and view 3D turn arrows directly on the cube.
• Adaptive Foldable & Tablet Layouts: Automatically adapts to tabletop posture, unfolded dual-pane screens, wide tablet displays, and compact phones.
• Offline QR Cross-Device Sync: Instantly transfer your solve history, custom cubes, and training progress between your XR headset, tablet, and phone using offline multi-page QR codes—no account or cloud login required.

🧠 STEP-BY-STEP 3D SOLVER & INTERACTIVE TIMELINE
• Powered by Kociemba's Two-Phase Algorithm to compute fast, compact solutions from any valid scramble or scanned cube state.
• Step forward, backward, pause, or scrub through the interactive move timeline with synchronized 3D directional turn arrows showing every layer rotation clearly.
• Hands-Free Voice Control & Spoken Coach: Say "Next", "Previous", "Play", "Pause", "Scramble", or "Solve" while keeping both hands on your physical cube.

📷 LIVE CAMERA SCANNER & COLOR CALIBRATION
• Scan all 6 faces of your physical cube in seconds using guided auto-capture.
• Custom Center-Square Calibration: Having trouble with non-standard sticker shades or lighting? Calibrate directly from your physical cube's center squares for pinpoint color detection.
• Supports custom color schemes and stickerless cube palettes.

🎓 STRUCTURED PROGRESS TRAINER & CFOP ALGORITHM LIBRARY
• Guided 4-Phase Mastery Curriculum: Progress from your very first complete solve down to sub-15-second speedcubing with interactive lessons, recognition guides, and timed mastery exams.
• Complete F2L, OLL & PLL Reference: Practice 119+ essential speedcubing algorithms (42 F2L, 57 OLL, 21 PLL) with 3D playback, fingertrick tips, and case setup previews.

⏱️ WCA SPEEDMAT TIMER & SESSION ANALYTICS
• Authentic hold-to-start inspection and timing workflow (+2 and DNF penalty support).
• On Android XR headsets, use real hand tracking to rest both hands on the virtual speedmat pads just like a competition timer!
• Track solve history, best times, Ao5, Ao12, and interactive progress graphs across multiple named sessions.

🔒 100% PRIVACY-FIRST DESIGN
• All camera scanning, voice recognition, and hand tracking run locally on your device in real time.
• No camera images or audio recordings are ever saved or uploaded. No ads, no subscriptions, and no account required.
