DONT WASTE YOUR MONEY. The app is good, but when u pay to see who sent different comments u get nothing. Nothing changes. Get the app only if you're fine with it staying anonymous. Don't pay it's not worth it it's basically a donation to them. I emailed them 3 times for a refund with no reply. Don't waste your time, don't waste your money. The option then come up to pay again after a couple of days. Absolute scam.
