Interesting. I would have thought that the developer would have contacted me at some point, but this is the first I have heard of this app. I have not downloaded it yet, but I am working with a company right now about creating an app that I hope can help slugging as well. I should know something within the few months.
I saw small signs up at the Horner Road lot for another app called SmartSlug. https://smartslug.com/ I wounder if people will start using them. I had no idea that the sign was advertising an app until I googled it.
