SkyLens Star vs UnivMap

Point your phone at the sky and SkyLens Star tells you what you are looking at. Names appear over your camera's live view — 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 — 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 — 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 — this app has you looking up.

UnivMap is a navigation app. Search for places, get directions, and check your estimated time of arrival. -Search Type in where you want to go. Alpha Centauri, the Orion Nebula, or that black hole at the center of the galaxy. -Directions Starting from your current location, UnivMap works out the distance and arrival time — and kindly routes you around interstellar pirates and high-radiation zones. To Voyager 1: 25.599 billion km, about 23 hr 43 min at the speed of light. It never stops moving, so we time it just right — it reaches the destination to meet you the moment you arrive. -Choose how you travel Rocket, car, bike, or on foot — take your pick. Drive to Mars and the route card will warn you it's uphill the whole way. -Save your places Set your Home and Work, and get directions home with a single tap. -Reviews Every place has ratings and reviews. The Moon currently holds 5.0 stars across three reviews — one visitor wrote: "That's one small step for a man, one giant leap for mankind." -Works offline No connection required. No data collected. -Search galaxies, get directions, check your ETA. The nearest neighbor is over four years away — pack snacks.
