Very nice app

My only complaint is the affiliation with The Good Book Company. There aren't going to be any topics about alternative life styles. Mainly your career, straight relationships and money. That being said the only audio book options that aren't just an AI voice are the ones from The Good Book Company.
Definitely not something I would subscribe to or purchase outright but the free book a day is nice.

Service is a rip off - avoid at all cost

I signed up for the free trial and extended it for a one week subscription. When I logged into the system it provided me with a button to utilize my subscription but that automatically converted me to an annual subscription. When I clicked the link to contact the developer it brings up an email screen with a blank to Line: clearly they don’t want to be contacted. The next thing I noticed was that it had also charged a second weekly Subscription. (Which got refunded when I requested a refund through Apple on the annual sub.) I filed complaints with both the credit card and Apple but I can’t contact the vendor directly. Sure seems like a scam to me. Avoid at all cost

No customer service?

Was going to sign up today but a number of reviews referred to the lack of customer support so I thought I’d better check that out. Was not able to find any email addresses but I did find a phone number to call so I called it. Here’s what I got: no ring but immediate recorded music. No message of any kind, just music. I’m letting run just in case but it’s been 10 minutes now and it’s just music, amateurish light jazz. Guess I won’t be using this app. Too bad, seems like a good idea but with zero customer service or support or contact I’ll pass, you should too. For reference, today is a Friday, its 12:30 pm Central Time, 10:30am Pacific.
