I have both the paid version of scout and wdw too ls and the tools one notifies me first every time. As much as 20 minutes sooner. For the price I had to test them both out lol I will say customer service on tools has been outstanding.
So weird, I've heard the opposite. A couple of people have said in one of my fb groups that Scout notifies them several minutes before tools. It seems like everyone has different experiences. I've had a lot of luck with Scout helping me move around some of the times for my ADRs but I'm still waiting for BOG to open up on my MVMCP night.
