Space Telescope is an astronomy app for people who actually go outside and look up. See what the James Webb Space Telescope is observing right now. Decide whether tonight is worth staying out for. Catch the next visible ISS pass over your own location, and follow the rocket launches coming up. WHAT WEBB IS LOOKING AT, RIGHT NOW Webb's current target, science category, proposal, instruments and scheduled times, refreshed every five minutes while the view is open. Tap through to the proposal or the full observation schedule. A REAL PLAN FOR METEOR NIGHT Most meteor apps hand you a peak date. This one tells you what you will actually see. Set your location and how dark your sky is, and get an honest meteors-per-hour range, the best viewing window, where to look, how much the Moon will wash out, and what 30, 60 or 90 minutes outside is likely to be worth. Two alerts that matter: a heads-up the evening before, and a nudge when your window opens. Cloud cover is not included, so check the weather before you commit. THE ISS, OVER YOUR HOUSE Live position, altitude, velocity and orbit, plus crew, expeditions, dockings and visiting vehicles. Seven days of passes for your location with quality, direction, peak elevation and duration - set a 10-minute alert or drop the pass straight into your calendar. LAUNCH DAY Upcoming launches with live countdowns, status, provider, rocket, pad, launch window and webcast link. One tap for a reminder 15 minutes before liftoff. GALLERIES WORTH SCROLLING Imagery and mission guides for James Webb, Hubble, Chandra, the Nancy Grace Roman Space Telescope, Artemis, Mars and the ISS. Follow Roman's countdown, instruments and journey to L2. Pinch to zoom, save, share, like and comment. Turn on alerts only for the galleries you care about. PICTURE OF THE DAY NASA's Astronomy Picture of the Day, image or video, with the full expert explanation and an optional daily alert. AND WHEN YOU WANT MORE - Tonight Sky: sunrise, sunset, Moon phase, illumination and twilight - Space Weather: Kp index, solar wind, aurora probability and active alerts - Cosmic Calendar: meteor showers, eclipses and other sky events - Exoplanets: discovery method and year, distance, orbit, mass, radius, temperature, host star and habitable-zone marker - Community astrophotography: post your own shots with gear and conditions - Space wallpapers for your phone - Quizzes, points, levels and global leaderboards - Ask an Astronomer, and live chat rooms in 10 languages - Full interface in English and Spanish PREMIUM Space Telescope is free, with ads.

About

Untranslated

Features
Read full description

Untranslated is a language-learning app built around real videos, interactive captions, and understanding words in their original context. Instead of replacing what you are watching with a complete translation, Untranslated helps you follow the original language more confidently. Choose a video in the language you are learning and watch with interactive captions. Words highlight as they are spoken. When you miss something, tap the word to see its meaning in that sentence, hear its pronunciation, save it with context, and continue watching. Learn from videos you choose Build lessons around real videos you genuinely want to watch rather than scripted textbook conversations. Tap unfamiliar words Captions become interactive. Tap a word when you need help without searching elsewhere or losing your place in the video. Follow the word being spoken The current word highlights as it is said, so you can stay with the original line while you listen. Hide easier words Choose a level from A1 to C2. Words below it fade to a light underline, so the captions match your level and you tap only when a harder word needs help. Understand the specific moment A word can mean different things in different situations. Untranslated explains the meaning that fits the sentence you are watching. Save words with their context Keep useful vocabulary alongside the sentence and video where you encountered it, making each saved word easier to remember. Review at the right time Saved words stay open until you can produce them from memory. Practise their meanings, prove them twice, and they become learned. Follow your learning path Resume recent lessons, practise the words still open, revisit what you have already proven, and see where you are from one place. See what each session added Finish with a clear recap of the words you explored, time spent with the video, and progress made through it. Untranslated is designed for immersion without leaving you lost. Keep watching the original. Understand more of it.
