Okay
Response from developer
I am very sorry to bring you a bad experience. You can experience some basic functions for free. If you want to use professional features, you can purchase a membership or try it for free. Because Apple will automatically renew the subscription, if you subscribe to the free trial, you need to cancel it 24 hours before it expires.
Bad
