Do not get

You only get to use for 5 seconds before you have to wait 10 seconds to use again. The constant pausing make this app unusable

Scam

There is zero way to cancel if you upgrade.

It’s not free

This app is a joke, it kept popping up adds for $1.99 upgrade every .10 seconds. All I need is to find a stud once why would I pay a fee from a free app?

Nothing but ads

You can only use the app for about 5 seconds before being prompted to upgrade or wait 10 seconds to continued followed by the same pop up only 5-10 seconds later
