Planet Pointer

Planet Pointer turns your phone into a pocket sky guide. Pick one target β a planet, a star, a constellation, a satellite or a deep-sky object β and an on-screen arrow guides you until your phone is aimed right at it. Or point the camera at something you don't recognise and let the app tell you what it is. Simple, focused, and accurate. POINT AT THE SKY Choose what you want to find and follow the guide arrow. When you're locked on target, the phone confirms with a gentle vibration. The live camera view helps you line up the guide with the real sky. WHAT'S THAT? IDENTIFY MODE Point the camera at anything in the sky and tap it to identify it. A phone compass is only accurate to about 5Β°, so the app never hands you a confident answer it cannot back up: you get the most likely object with a match percentage, plus anything else near enough to be a real possibility. Ask which star that is and get an honest answer instead of a guess. WHAT YOU CAN FIND - The Sun, the Moon and all 7 planets - 33 of the brightest named stars - All 88 constellations, drawn as connect-the-dots figures over the live sky - Deep sky: nebulae, galaxies and star clusters β Orion, Andromeda, the Pleiades and more - Live satellites β including the ISS, Hubble, Starlink and more β tracked in real time with upcoming pass predictions ACCURATE & OFFLINE Positions are calculated on your device using a precise astronomy engine, with true-north correction from the World Magnetic Model. No internet needed for the core features. MORE TO EXPLORE - Sky Events (Pro): eclipses, meteor showers, planet conjunctions and the next ISS pass β tap to jump there - Time Travel (Pro): shift the sky forward or back in time to see where everything will be - Info cards with facts, figures and mythology for every body and constellation - Favourites, brightness/magnitude data, and a search you can filter to "visible now" SPEAKS YOUR LANGUAGE 13 languages built in, and 66 more available to download with Pro β 79 in all, with translated planet, star and constellation names. BUILT FOR STARGAZING - Night-vision red mode to protect your dark-adapted eyes - Spoken sky: hear your target and aim guidance read aloud - Choose km or miles, set your location manually, and more FREE & PRO Free, forever: the camera pointer, the Sun, the Moon and all 7 planets, identify mode for the planets, and a few famous stars, constellations, deep-sky objects and satellites to try. Planet Pointer Pro is a single one-time purchase β no subscription β that unlocks every star, constellation, deep-sky object and satellite, Time Travel, Sky Events, unlimited favourites, the full night-vision options and every language download. PRIVACY FIRST No account. No ads. No trackers. Your location and camera are used only on your device to point you at the sky β they're never recorded or sent anywhere. Look up. Point. Find it.

Verdict
The clearest difference is in-app purchases: Deep Sky Scanner at none against Planet Pointer's 1. Deep Sky Scanner also leads on device support (3 vs 1). On price, update cadence, ads and iOS requirement there is nothing between them.
