Reface App is a Scam

Just want to make sure everyone knows that the Reface app is a total scam. The app itself is trash (it recommends like four ugly hairstyles) and you think you're paying $4 one time for the app but it's actually a $20 a month subscription and THERE IS NO WAY TO CANCEL IN THE APP OR GOOGLE PLAY.

I have reached out to the company numerous times and have not received a response.

it's a total scam. Just want to make sure no one else makes the same mistake. I feel like an idiot.
