It was fun, but cancel your subscription before logging out
It was a fun, quick test. Not sure how accurate but it seemed to be fairly accurate. It didn't warn me that I was subscribing. I had to go into my account to see that I had been signed up for a $19.99 monthly subscription. I was able to cancel that easily. It said my test was 99 cents but it charged my credit card $1.99 for a 3 day subscription that I didn't actually agree to when signing.
