New to this app and teachings and happy to be here

Only my first day using the app. Astrology and it’s many facets are still relatively new to me and I’m finally trying to understand. Even though periodically over the years I have checked a horoscope here n there, I never took it too seriously. But more recently I’ve started to learn a bit about the different sun and moon signs and even delved a bit into numerology (which I’m not sure if that has any direct relation but is interesting nonetheless.) One of my short and long term personal goals have been just to learn as much as I can about everything... everything I feel I’ve been lied to or mislead about my whole life... which come to find out is just about everything 🤦🏻‍♀️ so needless to say I have a long road ahead of me. Id like to become more openminded to the limitless possibilities of our individual lives paths. Callings or just deep-down knowings that for so long I’d preferred to ignore and just take whatever life throws at me Instead. I’ve downloaded this app specifically to help me on my journey in hopes that these daily reminders and guidance will be a valuable tool in my personal growth so that I can in turn help others. So, here’s to hoping I can learn to navigate this app and use it to its fullest potential (as I have the tech skill if the over 80 crowd).
Thanks for the insight

Eek! Scary to see the stars are true to form!

Seriously, this really creeps me out. I have had multiple situations I have been through and still going through. Good, Bad, New, Old, and Challenging. When I get a reminder for the day or I just happen to read it for the day, my horoscope, my draw drops! I am in awe of understanding along with the stars providing comfort on what to do or why the day is going about as it is.
The key to the success for you, as an individual, is your “BIRTH TIME”. It’s imperative you get to your time, as close as possible. Your birth time is located on your Birth Certificate.
When there is a rough day, there is also a resolute on how to work through it. I have a handful of friends now on this app. Some will make their horoscope visible and others will not. Either way, the accuracy on their readings is the same as mine, spot on.
If you believe in the stars, I highly recommend this app! If you have uncertainty, on the basis of the stars knowing your feelings or encounters and are unsure of believing, I recommend this app! If you’re a nonbeliever, I challenge you to try this app!
Know why or what is happening to you. Whether it be good, bad or just need some understanding, This is a true enlightenment for your psyche. Enjoy and let the stars help you balance your life with understanding. Highly recommend!!!

I love this app, I often start my morning with it. Even if you’re not hugely into astrology or even a skeptic who’s just “playing around with it” there’s always some good nuggets of information and motivation to get you going. Now with the good comes the bad, and here’s where my suggestion comes in: please make the “Talk About It” section optional, with an on/off switch in settings. 1/2 of the people leaving notes are leaving very childish, unrelated notes and the other 1/2 are so full of themselves it makes me want to puke and ruins my otherwise magnificent costar experience. Nothing makes an experience less enjoyable than having to listen to an idiot ramble about how special they are cause they got a little Aires in their chart, or how secretive and evil they are with their Saturn in Scorpio, or how sad and lonely their life is being a misunderstood Venus cancer. I’m pretty sure these are children who are projecting what they think they know about astrology onto their own life and spreading their poor ideas about astrology to other gullible readers. Even so the point is please make this section optional for the “At A Glance” section. Otherwise perfect app I can’t even bring myself to give four stars for such a small problem.
