Highly recommend not downloading this app, appears to be at best a terrible user experience, and at worst a blatant money grab. You can download the app for free but to do LITERALLY anything you have to upgrade to premium for $20. Once you pay, it immediately asks you to rate the app and won’t let you escape the dialog box without hitting yes or no. Once I did that and then tried to use it, it crashed and would not reboot. I was able to get a refund from Apple. Don’t waste your time or money on this. Not worth it.
