Automatically charges your card

It’s only free to download. To actually use it, you have to buy a subscription. Even the 3 day “free” trial comes with you automatically subscribing to your card being charged weekly. I haven’t been able to find where to cancel the subscription. It’s hidden too deep in some settings so I’ve not been able to find it.

Not good

Drop the price to free from $2.99 but require a monthly subscription to use. Cannot even begin to use without a subscription. Avoid this app!!!

Response from developer

Thank you. We constantly update the application to provide the best service for you.

Free this week, but cannot test it out

Having this as a free app, sounds great! But upon first launch, you cannot test it out without buying a subscription. How can I decide if I want it?
