I downloaded the app. It asked that a card be linked. As soon as the card was linked, they took $17.99 for a "membership." I immediately contacted support and told them I don't want a membership, and I want a refund. I was told I could get a refund if I wrote a positive review on Trust Pilot. I refuse to write a false review, and told them that. They have since stopped responding to my requests for a refund.
Recommendation: Stay away!
