Every Planet
Read full descriptionHide full description
Every Planet turns the whole observable universe into something you can hold in your hand. Tap once and the World Forge builds a planet that has never existed before: an ocean world wrapped in cloud, a ringed gas giant, a lava world cracked with light, a frozen wanderer far from its star. Every world is unique and generated from a single seed, so the one you just made is one you will never see again unless you keep it. The worlds are imagined. The physics behind them is not. Every planet carries an honest science dossier. Its year is computed with Kepler's third law. Its warmth comes from the real luminosity of its star and the greenhouse effect of its air. You see its distance from Earth, the year your light would arrive, the length of its day, its host star's temperature, and whether liquid water is even possible. Estimates carry honest uncertainty, the way real astronomy does. WHAT YOU CAN DO Forge a world Make a new world in a tap, or aim the Forge toward what you want to find: water, a giant, two suns, or simply something strange. Keep the ones worth keeping Save a world to your Archive, give it a name, and write a note about why you stopped there. Unsaved worlds are gone the moment you move on, so the good ones are worth catching. Read the real science Open any world's dossier for a plain, careful explanation of its orbit, star, mass, and light, tied back to the methods astronomers actually use. Learn the universe, and remember it The Observatory holds short daily recall questions built on spaced repetition, so real ideas actually stick. Track a gentle streak and watch how much of the sky feels familiar. Travel outward Every discovery carries you about eight percent deeper into space, past real landmarks, all the way to the edge of the observable universe. Go deeper in the Observatory An orbit lab to move a world through space, a field guide to the stars that make planets possible, an atlas of twelve genuinely strange real worlds, a guide to how we find planets we cannot see, and the big numbers that put it all in scale. QUIET BY DESIGN No account. No ads. No tracking. Everything you make stays on your device. Optional ambient audio for the long trip outward. Built to be calm, factual, and yours. There are around seven hundred quintillion rocky planets out there. Humanity has confirmed about six thousand. Every Planet is a small, honest way to feel that scale, one world at a time.
SkyLens Star

Point your phone at the sky and SkyLens Star tells you what you are looking at. Names appear over your camera's live view โ the Sun, the Moon and its current phase, five planets, about 45 of the brightest stars, and 8 constellation figures drawn in. Everything is computed from real astronomical algorithms for your exact coordinates and the exact moment you are standing there, not read off a canned star chart. WHY IT ACTUALLY LINES UP Every phone's compass gets pulled off course by steel in walls, desks, speakers and magnetic cases โ often by 10 to 30 degrees. Most sky apps leave you to guess. SkyLens Star gives you a fix: point at the Moon or the Sun, tap Snap, and the app measures its own error against a body you can plainly see and corrects itself. There is a manual offset slider too, if you want to nudge it yourself. TAP ANYTHING Every labelled object opens a card with its altitude, azimuth, brightness, and a short plain-language description of what it actually is. The descriptions ship inside the app, so they read the same on a mountain with no signal. WORKS COMPLETELY OFFLINE No account. No sign-in. No network requests at all. Airplane mode makes no difference to how it behaves. NOTHING IS COLLECTED The camera feed is drawn on screen and never recorded, saved, or sent anywhere. Your location is used only to compute the sky above you, in memory, and never leaves your phone. There are no ads, no analytics, and no tracking of any kind. SEVEN LANGUAGES English, Simplified Chinese, German, Spanish, French, Japanese and Brazilian Portuguese. Switch from the gear icon inside the app โ you do not have to change your phone's system language. A NOTE ON USE SkyLens Star is for casual observation and learning. It is not a navigation instrument. Never look directly at the Sun, with your eyes or through the camera. And watch your step โ this app has you looking up.

Verdict
The clearest difference is in-app purchases: Every Planet at none against SkyLens Star's 1. SkyLens Star's advantage is update cadence (monthly vs every 18 months). On price, ads, device support and iOS requirement there is nothing between them.
