Inkora — A Coloring Book Built From Scratch Inkora is not a template. Every tool — from the gap-bridging Smart Fill to the 13-tip brush engine — was coded from the ground up to give your coloring results that off-the-shelf apps cannot deliver. — SMART FILL THAT HANDLES OPEN LINES — Standard bucket fills overflow wherever an outline has a gap. Inkora's Smart Fill uses a custom gap-bridging algorithm with two independent controls you set yourself: • Gap Detection Threshold — how wide an open path the fill will cross, from a hairline crack to a deliberate opening. Set to zero for strict boundary-only fill. • Minimum Line Thickness — how thin a line must be before the fill stops treating it as a wall. Gives precise control over loose, stylized, or rough outlines. Color lands exactly where you intend, every time. — 13 BRUSH TIPS, TWO FAMILIES — • Classic: Round · Flat · Filbert · Fan · Comb · Rigger · Angle • Watercolor: Watercolor · Splatter · Chalk · Water Flat · Water Ink · Water Blot Five size levels per tip — from bold coverage to micro-detail precision. Every tip is an independent stamp shape, not a variation of a single base. — FIVE CREATIVE TOOLS — • Brush — paint with any of the 13 tips at any size. • Smart Fill — one-tap gap-bridging bucket fill with adjustable threshold and line-thickness controls. • Watercolor — soft-edge blending that layers like real paint. No hard digital edges. • Eraser — precise removal with full size control. • Move — pinch-zoom to 5× and pan freely for close detail work. — PROFESSIONAL COLOR SYSTEM — • 16 curated groups: Pastel · Jewel Tones · Neon & Vibrant · Metallic · Nordic · Warm · Cool · Forest · Skin Tones · Monochrome · and more. • Custom color picker: 2D HSV selector, per-channel RGB sliders (0–255), and Hex input (RRGGBB / RRGGBBAA) for exact color matching. • Full alpha transparency for translucent, layered paint effects. • Live color preview before every stroke. — SNAPSHOT SYSTEM — Save multiple named snapshots of the same illustration. Try completely different color palettes on one page without losing any version. Each snapshot stores the full tool, color group, and brush state — not just a flat image. — YOUR WORK, ALWAYS SAFE — • Auto-save on exit — return days later with everything intact. • One-tap export to your iOS Photo Library at full resolution. • History panel keeps every unfinished piece ready to continue. • 15-step undo for bold, worry-free experimentation. • Fully offline — no account, no sync, no internet required. — 293 ORIGINAL ILLUSTRATIONS ACROSS 9 THEMES — Forest Animals · Ancient Japanese Town · Sweets · Dragons · Underwater Ocean · Samurai Warrior · Gothic Cathedral · Cherry Blossom · Zentangle All original line art — clean, detailed, and built specifically for digital coloring. New illustrations added with each update. — FEATURES AT A GLANCE —
