I love that it has multiple features so you could customize your own rules! It can be confusing at first because there are many different tabs to go through while figuring out all of its capabilities but once everything works well with this program then they will never switch back again!! Definitely check them both (the free version vs paid) before making any final decisions either way.
We use their yard management service in our trucking business now since we started using GPS technology years ago; however when my manager didn't have time he would just call me instead sometimes even texting us from his phone lol - very nice communication between him/our drivers who work together daily without actually meeting each other face-toface yet still able see what's going down within miles away thanks to tracking programs nowadays.
