This is the SIMPLEST app to use, of all the apps out there.
100% Ad-free! (even in the free version!)
And NO Astronomy degree required! Simply give it your location, and it’ll tell you whether you’re in the path of totality or not, and also when the eclipse happens for you!
And if you upgrade, you’ll be able to use your device’s GPS to get the most accurate information possible! This will be CRITICAL on eclipse day!
