SatellitePlus: Orbit Tracker
ISS passes, radar & widgets
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Follow satellites free in the app. One-time Pro adds Home Screen widgets, Apple Watch, and Dynamic Island with its Lock Screen Live Activity.
Where is the ISS now? When will your next satellite pass begin? SatellitePlus brings a 3D Earth, polar radar and pass predictions together in a tactile, metal-and-glass observation console.
FIND YOUR SATELLITE
Rotate Earth, select an orbit, or search by satellite name and NORAD ID. Filter by group, country or orbit type. Keep a followed list so your favorite targets are easy to find again.
PLAN YOUR NEXT PASS
Check direction, elevation and distance on the radar. The pass dossier brings together rise, peak and set times, maximum elevation and orbit-data age. One active local reminder is included free. Following a satellite does not turn on notifications.
TAKE YOUR TARGETS WITH YOU
In-app following and phone console controls are free. Pro is a one-time purchase for Home Screen widgets, Apple Watch, and Dynamic Island with its Lock Screen Live Activity. No subscription. Restore your purchase from the in-app store.
On Apple Watch, view your followed list and a wrist-aligned polar trajectory. Sync with iPhone to store the next 48 hours of trajectories locally, including positions below the horizon. The cache works offline within its saved period and needs a new sync to refresh. Start an orbit session yourself to see it on the Lock Screen and, on supported iPhones, Dynamic Island. System update timing applies; these surfaces are not continuous background tracking.
READY FOR EXPLORATION
No app account is required. Location access is optional; without it, a default observer is used. A bundled catalog and local cache keep basic exploration available when a network update is unavailable. iPad gives your instruments more room in portrait and landscape.
Predictions use public orbital data. A pass above the horizon does not guarantee naked-eye visibility: illumination, weather, obstacles and data age matter. SatellitePlus is for personal observation and learning, not navigation or safety-critical use.
