Satvis is a free, open-source satellite tracker for iPhone and iPad. It draws more than 16,000 satellites on a 3D globe in real time: Starlink, GPS, weather satellites, the ISS and many more. Set your location and it predicts when each one passes overhead. The sky view shows the sky from where you stand. Point your phone up to see the satellites in that direction. WHAT IT DOES • Visualize satellites on a 3D globe in real time, propagated on the device with SGP4 from CelesTrak's element sets • Show points, labels, orbits, orbit tracks, ground tracks, sensor cones, 3D models and ground station links per satellite, colored by orbit class (LEO, MEO, GEO, HEO) • Switch catalog groups on and off (Starlink, GNSS, weather, Earth observation, crewed stations), or search for a single satellite • Select a satellite to see its orbit, its next passes over your locations and its spacecraft details: country, operator, manufacturer, bus, mass and size • Track a satellite: the camera flies to it and follows it along its orbit • Save your location or any point you pick on the map, then list the upcoming passes over it and get a notification before one starts • Find satellites overhead in the ground-level sky view, aimed by dragging or by pointing your phone, with the camera's picture of the sky behind them • See which satellites you could spot: the sky view dims those in Earth's shadow, too far away or in a daylit sky • View the globe in 3D or flattened to 2D, over the base map, star field and terrain you choose: satellite imagery, Earth at night or the day's VIIRS imagery • Start from the featured views, bookmark your own, and share any view as a link: it opens the same view on satvis.space • Open satvis.space links straight in the app • Keep using it offline, from the satellite data it last fetched WHERE THE DATA COMES FROM Element sets come from CelesTrak, refreshed several times a day, and are propagated on your device with SGP4. Spacecraft details come from Jonathan McDowell's GCAT. FREE AND OPEN SOURCE No account, no ads, no in-app purchases. Developed in the open at github.com/Flowm/satvis under the MIT license.

A clock so beautiful you'll watch it change. Every digit is drawn by tiny analog clock faces—24 in all—their hands sweeping into position each minute to spell out the time. Part timepiece, part kinetic art. Give it sixty seconds. You'll never want a plain digital clock again. WHY YOU'LL LOVE IT • A living display for your nightstand, desk, or shelf • Minimal, elegant, and mesmerizing to watch • One-time $0.99 — no subscriptions, no ads, no in-app purchases HOW IT WORKS Each digit is a 3×2 grid of six clock faces. Forty-eight hands choreograph themselves every sixty seconds, sweeping smoothly to their new positions to redraw the time. ALARMS Create alarms with a label, choose which days they repeat, and set a snooze from 1 to 30 minutes. When an alarm fires, a countdown Live Activity appears on your Lock Screen and in the Dynamic Island, showing exactly how much snooze time remains. ALWAYS-ON / BEDSIDE MODE Long-press the clock to enter always-on mode: the display dims, overlays disappear, and the idle timer is disabled—perfect as a quiet bedside or desk clock. Tap once to exit. AIRPLAY Send the clock to an Apple TV or any AirPlay 2 display. It fills the screen in the full television layout and stays perfectly in sync. WIDGET Add the medium Home Screen widget—independently configurable per instance for time format, theme, and accent color. CUSTOMIZE • 12-hour or 24-hour format • Light, Dark, or System theme • Hand accent: System, Blue, Green, or Amber ACCESSIBILITY Reduce Motion snaps transitions instead of sweeping. Increase Contrast switches to a high-separation opaque palette. VoiceOver reads the current time as one element. The same beautiful clock is available on iPhone, iPad, Mac, and Apple TV.
