I just got a Celestron StarSense telescope for Christmas. The StarSense app is also GREAT btw, but it doesn't tell me the quality of the view in the night sky on any said night like Sky Tonight does. I always defer to this app to see how much visibilty there will be when I want to use my scope. I have to say it's pretty accurate, at least in my area. I do wish the calibration was a little more spot on, but I can usually fix it manually. All in all it's a great app and worth the price.

I am absolutely obsessed with this app for absolutely everything I need for astronomy; I'm learning the constellations, and there are an array of tips and even dates for astrophotography opportunities and tips, you can track Starlink satellites and other objects, . The Moon approached Venus tonight, the Quadrantids Meteor Shower peaks, if you have this app downloaded, it will remind you about sky events with a notification or alarm. I'm actually having so much fun nerding out on learning.

Sky Tonight App is amazing. Extremely intuitive design and sleek user interface that provides a ton of details, options, functions without cluttering, or looking like it was meant for an astrophysicist. Graphics are beautiful; every line, word, or object has an interactive component. Feeling lost or overwhelmed, search Sky Tonight App on YouTube. Six short videos walkthrough every function, icon, and feature clearly in detail. Must have for hobbyist, would be astronomers, and serious fanatics.
