Apps and Software

Here you'll find some of the best eclipse-related apps and software available, as judged by members of the AAS Solar Eclipse Task Force. To avoid overwhelming you with too much information, we've intentionally weighted our listings toward resources that are relatively new, up to date, and/or especially relevant to the October 2023 and April 2024 American solar eclipses. We've also considered quality, of course; if an app or software is listed here, we think it's of high quality. If it's not listed here, that doesn't mean it's not of high quality — it just means we can't list everything (or haven't heard of it). If you have, or know of, a resource that you think belongs here, please contact us; we can't guarantee that we'll add the item to our website, but we will consider it.

Dan McGlaun's Web-Based Eclipse Simulators (and More)

Indiana-based eclipse enthusiast Dan McGlaun has built a remarkable website at eclipse2024.org. Among its many features is the Eclipse Simulator, which shows what the North American eclipses of October 14, 2023, and April 8, 2024, will look like from any city or town where any part of either eclipse is visible. It works on any device with a web browser and includes controls for zooming in or out and speeding up, slowing down, or stopping the simulation. There's also a library of prerecorded videos made with the simulator showing both eclipses as viewed from more than 2,000 places, as well as an extensive collection of pages with location-specific information about the eclipses for virtually every city and town touched by one or both of them. On top of all that, everything on eclipse2024.org, including the simulator and its associated videos and pages, is available in English, Spanish, French, and Portuguese!
