The beautifully designed app to enhance your experience watching the total solar eclipse on Tuesday topped the App Store. With 140,000+ lifetime downloads across iOS and Android, quite simply named The Eclipse App, you can watch the astronomical event for free, including cloud cover forecasts, guides that pinpoint when totality will occur at your exact location, and information about local events, parks and viewing sites in your area.

The app itself was born out of a partnership between the independent space interest organization, The Planetary Society, and The Eclipse Company, a tech company formed around the time of the 2017 Great American Eclipse in an effort to help more people witness total solar eclipses.

The companies initially released a user-friendly eclipse map to assist with finding a viewing location for the annual eclipse on October 14, 2023.

The Eclipse App, which went live in the U.S. and Canada in February, is generating revenue by selling users access to livestream for $3 through in-app purchase. There are now around 9,800 paying users as of Monday, according to data from app intelligence firm Appfigures. The app began its App Store ascent late on Sunday with 35,000 downloads on the App Store and began moving up the charts. The company says Google estimates put their download totals a couple of days behind; the new figure is likely well north of 140,000 downloads by now.

The app is currently number one in its category (Travel) and number nine Overall in the US App Store and eighth in its category via Google Play.

And aside from that, the app doesn't seem to be getting much traction from any Apple Search Ads campaigns but is gaining traction organically.

App Store: Review 40, Average rating - 4+ stars; 22 one-star reviews. It seems more dissatisfaction with the Android version of the application.

Promise the app will offer subscribers the ability to explore U.S. states and Canadian provinces along the path of totality as well as community events in search states. You can even use the timer to know when the moment of totality is for your exact location, so you can put on your eclipse glasses and watch. You can also check your local forecast and subscribe to local events and check out other local points of interest. Parking information for many events is included.

Another app from the same company, Solar Snap, also made it to No. 3 on Top Charts for its handy photography assistant for shooting photos of the eclipse.
