Full screen video ads. Video ads pay more than banner ads. Thank God the ads I seen in the short 30 seconds I used the app for were a few seconds. There is no reason to choose to have video ads in an app that doesn't play video. It's out of place and extremely unwanted. No option to disable ads. In an environment that this app would be needed, blaring sounds and disabling app usage is unacceptable. The extra star because it's not the worst ad delivery app.

I was thinking of paying for pro but after seeing how many tracking attempts this app try to get my personal information I'm just going to delete it. Teaming up with a company that has enough of our personal information is pretty low. We can't do anything without someone trying to get something out of us. We'll you can have your team google app back. You might not collect our data but you're complicit in letting others do so through your app. So which is worse? Conduit or the receiver?

Dear blue. The Pro version doesn't have an advert library, so it doesn't collect any data

For what it is, it's a pretty good app, I feel like it's missing its final touch though, I think it should be more in-depth informative and more dynamic in the circuit building part, but I'm sure that will come and when it does it will get five from me.
