This is fake app

this is a fake app. No one should install this app because they they said me that we give you 10 credits. If you have paid three ₹349 when I paid this amount, they haven't given me any credits what they show on their profile. So never trust this app.total scam.

Doesn’t work

I recently started using this app and also made a purchase, but most parts of it don’t work.

Perfect for overall review

I have been using this app for about a week and I enjoy the way that it responds to the answers immediately. Since I started using it I have seen so much improvement in my score.
