Coming up: The total solar eclipse of 12 August 2026 — where and when to see it →
Finsternis shows you every upcoming solar and lunar eclipse — and, more importantly, whether you can actually see it from where you are. A clean list runs through 2050; each entry tells you at a glance how it looks from your location: total, annular, partial, penumbral — or not visible at all.
Open any eclipse and follow its path across a real 3D globe: scrub through time, watch the Moon's shadow sweep over the Earth, read the exact local contact times. Set your observation point to any place on Earth — perfect for planning a trip to the path of totality. When the moment comes, the Sky Finder uses your compass to point you exactly where the Sun or Moon will be.
Finsternis computes every prediction on your device from NASA's public-domain data — no account, no tracking, works offline. (Place search needs an internet connection; everything else, including the eclipse maths, runs on your device.) For iPhone and iPad, in English and German — Spanish and Portuguese are coming in the next update. An Android version is on the way.
One purchase. No in-app purchases.
☀️ Safety: never look at the Sun directly or through the app without certified solar-eclipse filters.
