The Aug. 12 total solar eclipse is less than a week away! We know that eclipse planning can be daunting, so we’ve put together a list of great eclipse apps to help make things that little bit easier.

Over 15 million people across Spain, Greenland and Iceland will witness totality on Aug. 12, while almost a billion will bear witness to a partial eclipse, as the moon blocks a portion of the sun’s light without hiding its surface entirely, according to Time and Date.com. However, each person’s experience will be subtly different, whether it be the exact timing of totality, the terrain, cloud cover, or a myriad of other reasons.
