IRO – coloring book for adults

About

IRO is a calm, beautifully crafted coloring book for iPhone and iPad — built for those moments when you just want to slow down, breathe, and color. Hand-Drawn Isometric Worlds Color your way through richly detailed isometric scenes. Step into cozy spaces — coffee roasteries, sushi prep counters, Vienna kaffeehauses, plant shops, champagne cellars — or wander iconic cities like Kyoto, Lisbon, Marrakech, Buenos Aires, and Istanbul. New pages are added regularly. Pages of the Day A handful of pages unlock for free every day. No rush, no friction — just open IRO and start coloring. Professional Artist Tools Color with nine realistic tools — Brush, Pencil, Marker, Crayon, Watercolor, Fountain Pen, Monoline, Eraser, and tap-to-fill Bucket. Adjust size and opacity, pick any color from a full-spectrum picker or one of the curated palette packs, and watch the bucket fill spread out from your fingertip. Fully optimized for Apple Pencil with pressure sensitivity. Made for iPhone and iPad Edge-to-edge canvas, pinch-to-zoom up to 5x, two-finger pan, and a mini-map to stay oriented at the tightest detail. Optimized layouts for both iPhone and iPad. Time-Lapse Replays Every coloring session is quietly recorded so you can export a smooth time-lapse video of your work — perfect for TikTok, Reels, or Stories. Share Your Way Export your art as a 9:16 vertical for Stories and TikTok, or as a time-lapse video. Pick any background color, toggle the watermark, and share anywhere you like. Personal, By Design A quick personalized onboarding tunes IRO to your taste — light or dark mode, a mood-driven accent color, and gentle daily reminders if you want them. Quiet, never noisy. Never Lose Your Progress Your work saves automatically, stroke by stroke. Come back any time and pick up exactly where you left off, with full undo and redo when you want to experiment. Designed for Calm Every detail — from rounded typography to soft haptic feedback — is shaped to make coloring feel soothing, not stressful. Start coloring. Start relaxing. ---- Note: some features in IRO Coloring Book require a subscription. Free trial is available.
