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.

Read full description

PersonalCode is a free app for anyone who wants to keep the people in their life in mind. No more forgotten birthdays. And a chance to understand your loved ones a little better. The tool behind this is numerology and classical zodiac signs. Date of birth and name, combined through centuries-old calculation rules, become a personal number that says something about what someone is inwardly oriented toward. Plus Western and Chinese zodiac signs with elements and character traits. Not a newspaper horoscope, more of an invitation to look a little closer. YOUR PEOPLE Add the people who matter to you. From your address book or by hand. PersonalCode reminds you of every birthday, years in advance. With photo, notes and a relationship label. FOR EACH PERSON YOU SEE Life path number, Western and Chinese zodiac, compatibility between the two of you. That is how you might understand, for instance, why a 5 thrives on change while a 4 prefers stability. FOR YOURSELF Your own life path number, expression number, heart's desire and personality. Plus your personal year and the daily energy that is in the air right now. PRIVACY, HONESTLY MEANT No tracking. No ads. No in-app purchases. All data about your people stays on your device unless you actively turn on cloud sync. Servers in Germany, GDPR compliant. Delete your account anytime, right from within the app. IF YOU ARE A PERSONALCODE.DE CUSTOMER Then the app also becomes your reading room. Analyses and books you have ordered there open here in the reader. Audiobooks keep playing in the background while you are out, with lock-screen controls. And every morning your personal daily impulse waits on the home screen, tuned to your numerology. PersonalCode is free, and will stay free. Analyses and books you order, if you want, at personalcode.de.
