Eclipse Predictor · 3D Globe

Step through the solar eclipses from 1900 to 2200, one after another, on a 3D Earth you can spin and zoom. For each eclipse the path of totality or annularity is drawn on the globe, with the point of greatest eclipse marked and a band showing where the partial eclipse can be seen.

The eclipse list is worked out on your phone when the app opens, using the open-source astronomy-engine library.
