3D Solar System vs Tryshadowing: which is better? (2026)

3D Solar System

Real-time 3D solar system simulator powered by NASA/JPL data, with eclipse predictions, live ISS tracking, and an AR SkyView constellation finder.

3D Solar System is a real-time 3D simulator of the solar system built on precise NASA/JPL orbital data. It shows the actual current positions of the eight planets and major moons, and lets you rotate, zoom, and follow any body in real time or at accelerated time scales. A dedicated Real Scale mode renders true relative sizes and distances instead of the exaggerated proportions used for visibility in normal view. The app includes a solar and lunar eclipse calendar covering 2024 through 2100, live tracking of the ISS, Hubble, and James Webb Space Telescope, and a near-Earth asteroid overview highlighting potentially hazardous objects. SkyView, a newer feature, uses the device camera, gyroscope, and GPS to match constellations to the real night sky above the user, with a constellation browser and time-travel controls to preview the sky at any date. Available as a web app and a native Android app, with Korean and English support.

Tryshadowing

Free English Shadowing with YouTube Videos — TryShadowing

Why shadowing works Shadowing means listening to a native speaker and repeating right away, copying their pronunciation, rhythm, stress and intonation. Because you imitate real speech instead of reading word lists, your mouth learns the natural flow of English — and your listening gets sharper at the same time. It works best with content you actually enjoy. TryShadowing turns any YouTube video — talks, vlogs, lessons, interviews — into a speaking exercise, so daily practice feels less like studying and more like watching. Free English speaking practice with any YouTube video Paste a link or pick a ready lesson, and we split the captions into short, speakable sentences. Play each line, shadow it out loud, record your voice, and get an instant pronunciation score so you know exactly what to improve. Practice American, British, Australian or any English accent — you learn from real videos, at your level (A1–C2) and on topics you care about, from everyday conversation to business, science and interviews. It's completely free and no account is required to start. Also train your ear with dictation Beyond speaking, TryShadowing includes a built-in dictation mode: listen to a sentence, type what you hear, and get scored word by word — with instant feedback on the exact words you missed. It's one of the most effective ways to improve listening comprehension and spelling. Dictation lessons are organised by topic and CEFR level (A1–C2), from greetings and small talk to numbers, travel and business. Practise a few sentences a day, review the words you mishear with spaced repetition, and watch your listening get sharper — a natural companion to shadowing.
