The handbook.

Canvas Workspace

The core drawing canvas supports high-refresh responsive pan, fluid pinch-to-zoom, infinite canvas rotation, tiling preview, and floating reference companion panels to display secondary images without disrupting your workflow.

Studio Tabs & Tools

Access tools instantly via the top and side panels:

• Insert: Add reference photos, shapes, fonts, and external assets directly to the active layer.
• Tools: Paintbrush, Eraser, Smudge, Selection, Transform, and Color Pickers.
• Edit & Canvas: Resize canvas, flip orientation, adjust DPI, and configure animation timeline assist.
• Share & Prefs: Streamlined export presets and customizable stylus pressure response curves.

Canvas Tiling

Toggle repeatable pattern generation with 25% overflow boundary tiles in cardinal directions. Essential for surface designers, concept artists, and seamless texture authors.

Drawing Guides & Grids

Accelerate composition accuracy with interactive guides:

• 2D Grids: Configurable spacing, opacity, and grid color.
• Composition Overlays: Rule of thirds, golden ratio, and diagonal framing guides.
• Perspective Guides: 1-point, 2-point, and 3-point perspective with movable horizons and vanishing points.

Dual Brushes

Combine two independent brush presets into a single composite stroke with dynamic blending, allowing complex textures (such as pencil grain overlaid on wet watercolor) simultaneously.

Stylus & Dynamics

Tailor your stylus feel with precision response:

• Map pressure, stylus tilt angle, and azimuth direction to stroke size, opacity, flow rate, and grain depth.
• Full compatibility with Samsung S-Pen, active USI styluses, and universal pressure pens.

24+ GLES-Accelerated Blend Modes

Instantly switch between Multiply, Screen, Color Dodge, Overlay, Soft Light, Linear Burn, Hue, and Saturation with real-time viewport compositing.

Masking, Clipping & Alpha Locks

• Layer Masks: Non-destructively conceal or reveal portions of a layer using grayscale values.
• Clipping Masks: Constrain the visibility of an active layer strictly to the shape of the layer directly beneath it.
• Alpha Lock: Lock pixel transparency to paint or shade existing boundaries without bleeding.

Adjustment Layers

Apply live modifier adjustments including Hue/Saturation, Gaussian Blur, Color Balance, and Curves across entire layer stacks or nested folders.

Typography Engine

• Fully editable text layers with live tracking, kerning, line leading, and baseline shift.
• Import custom .ttf and .otf files, or browse integrated Google Fonts.
• Curve text around shapes or paths with circle and line path-following options.

Vector Linework

Work with resolution-independent vector shapes and paths that can be scaled infinitely without raster blur or pixelation.

File Formats

Native .kyro container stores full artwork fidelity, layer hierarchies, and editable undo histories. Import and export readily to industry-standard formats including .psd, .procreate, .clip, .kra, .ora, .png, and .abr brush packs.

Automated Cloud Backups

Leverage Android’s Storage Access Framework (SAF) with automated incremental backup sync to Google Drive or local micro-SD storage.
