I would happily give this app 0 stars based upon assistance from the developer and 0 based upon their customer service. They give you a 3 day trial. Explain how you can cancel, yet, the ability to cancel is nowhere to be found. I've read every screen, went through all the options yet I can't find anywhere to actually cancel it. I also checked my Google play subscriptions and it's not listed. They also waited a full week (4 days after I was supposed to cancel) before charging my account.
