Dou vs Twinkleton

Dou is a tiny private space for you and your person. Draw something, tap send, and it lands right on their home screen. Say good morning with a heart. Send a terrible drawing of your cat. Leave a little "miss you" for when they unlock their phone. Dou keeps couples and close friends close, even across cities. ON THEIR HOME SCREEN • Add the Dou widget and the newest drawing from your partner appears right on your home screen. • Perfect for long-distance couples: a small sign of love they see every time they pick up their phone. DRAW IT. SEND IT. • Glowing brushes: neon, comet, rainbow, aurora, sparkle, fire, sakura, galaxy and more, plus a kaleidoscope symmetry mode. • Paper styles for your canvas, with new ones added online. • Send to your partner, or to the close friends you choose. TALK, NOT JUST DRAW • Chat with stickers and reactions, right next to your drawings. • History keeps every drawing you sent and received. PRIVATE BY DEFAULT • No phone number or contacts needed. Connect with an invite code, link or QR. • Drawings only go to people you connected with. No public feed, no strangers. • Delete your account inside the app any time. PLUS • Optional subscription: all sticker packs and a larger friend list. Everything else is free. Good to know: how fast a widget refreshes depends on your phone's battery and system settings. For ages 16 and up. Privacy Policy: https://liveink.app/privacy Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Twinkleton is a gentle, beautiful astronomy playground for curious explorers (ages 5–10). Spin a real 3D solar system in your hands, sit back for a movie-like flight past every planet, and discover how space works through playful, hands-on lessons — all guided by Luma, a friendly little astronaut. EXPLORE IN 3D • A real-texture Sun, eight planets, Pluto, the Moon, Saturn's rings and the Milky Way • Drag to orbit, pinch to zoom — like holding the solar system in your hands • Tap any planet to fly to it and open a friendly fact card • Slow it down, speed it up, or rewind time to watch the planets dance A MOVIE OF THE SOLAR SYSTEM • Immersive mode plays a calm, cinematic fly-through — drifting in from far away, then visiting each planet up close with gentle music LEARN BY DOING Ten interactive lessons turn big ideas into simple play: • Why we always see the same face of the Moon • Why you float with a tiny jump on the Moon (1/6 gravity) • How far the Sun is — light takes 8 minutes to reach us • How many Moons fit inside the Earth • Which planet is hottest (surprise — it's not the closest one!) • How much you'd weigh on every planet • What a satellite is — natural vs. man-made • How long a day lasts on other worlds • Solar and lunar eclipses, seen from space AND from Earth • A deck of cosmic fun-facts SAFE, GENTLE & AD-FREE • Fully bilingual — English and 繁體中文, switch anytime • Friendly voice narration reads every fact aloud • No ads, no links out, and no sign-up — privacy-first, anonymous analytics only • Works on iPhone and iPad Distances and sizes are scaled down so everything stays fun and visible — a toy model of the real thing, built to spark wonder.
