Over two years ago, I posted a review saying that it would be nice to finally get dark mode and the circular chart features on the Android version of this app. iOS has had those features for ages now, why not Android? And now, with this latest update... The UI on the app is even worse. The Home, Friends, and You navigation buttons are barely showing and are cut off. The top of the app is now going up into the notification section of my phone (Pixel 9 Pro). Terrible update.

It's amazing so far I love it and how accurate it is and how it explains so much that is so spot on with a lot of different houses of mine and how they intertwine with my daily life and personality. I just don't like how you have to pay to go more in depth or flat out $10 fees for certain parts of your chart ...even with the subscription. I guess that's how it is in 2025 right💁🏾‍♀️

I love it. My biggest issue are the call outs, as it's too accurate sometimes 😅. But even free, there's no ads and is really good at linking certain traits and aspects to your astrology. I've never seen something so... in depth and detailed. I'm definitely thinking about getting premium, but you don't really need it quite frankly cause the free stuff is just that good.
