The birth charts are interesting, seeing how all your planets align and what they pertain to. Like someone else said, the daily guidance tends to be angsty rather than offer any affirmation or actual guidance. Also be warned that if you purchase the 'add chart' option (where you can add a chart without coercing them to join the app. I wanted to map my baby daughters chart) this doesn't unlock the function, you are only paying to add ONE chart, then you have to purchase to add more 🤦‍♀️

I took a subscription but unfortunately I lost the device and I'm unable to access the account from another device now. I have contacted them through mail and they keep sending some random emails which are useless. I can't believe I subscribed to this app and I'm not able to access it 😭. Can't help to hold back, but this app provides the worst customer service.

I used this app without trouble for about a year. Then roughly two months ago, whenever I opened it, the app would just be a blank white page no matter what I did (restart phone, hard-stop app, uninstall/reinstall). Then for the past few days I get an error every time I open the app that says 'We're having trouble connecting right now. Please try again later.' I'm pretty disappointed as I've paid for extras which I can no longer access. Do you have some dev resource to fix Android bugs, please?
