About this app

Your guide to the 2 August 2027 Total Solar Eclipse, with the 12 August 2026 eclipse preserved for reference.

Eclipse Companion helps you choose where to watch, understand what you’ll see, and stay ready on eclipse day.

Designed for eclipse observers across Europe, North Africa, Egypt, the Mediterranean, and the wider 2027 eclipse path, the app brings together precise local eclipse timings, totality path guidance, location comparison tools, live eclipse simulation, weather context, horizon checks, phase-specific reminders, and a home screen countdown widget in one focused experience.

Available in English, Spanish, Portuguese, and Romanian, with more languages planned.
