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.

i mostly use the app for chaos mode. i like sending my partner little messages for them to get over the next few months. since the last update, though, it's also impossible to view chaos mode messages in the app. i get the notifications, but when you open the app, the button to actually view the message appears for half a second while the app is loading and then it's gone, which makes it very difficult to get screenshots of the messages.

I love it. My biggest issue are the call outs, as it's too accurate sometimes šŸ˜…. 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.
