FredSky turns your iPhone into a pocket planetarium. Look up, then at your phone, and instantly see what's overhead right now — the stars and constellations, the Moon and planets, and satellites passing over. The all-sky chart is centered on the zenith, like lying back and looking straight up, drawn for your exact location and moment. Raise your phone toward the sky and FredSky switches to a live camera view with the brightest objects labeled where you're aiming. Lower it, and you're back to the chart. • Live star chart — stars to naked-eye brightness, the classic constellation figures, the planets, the Moon at its true phase, and visible satellite passes. • Fully offline — the entire star catalog is built in, so the sky is right whether or not you have a signal. • Point-and-look — hold your phone up to identify the bright star or planet you're looking at. • Bird songs, too — tap record and FredSky identifies the bird singing nearby, then keeps your sightings as an illustrated life list. • Red night mode — a one-tap, dark-adapted view that protects your night vision outdoors. No account. No ads. No tracking. Just look up. Positions, phases, and pass times are computed properly — the numbers stay serious, even though the whole app is built to answer one question fast: what is that?
