The best feature of this app to me was that it allowed you as an owner, driver or office manager complete visibility into your business from anywhere in real time! I disliked how slow some features could be when using multiple people within our fleet. It took quite awhile for us at least 2-3 minutes just trying something simple like getting back up after taking off my phone while driving -.- We use yardmaster mostly with drivers but also sometimes other employees such as dispatchers who send messages out through their mobile device (usually cell phones). This has been great because we have never had any issues tracking where vehicles are located which helps reduce wasted trips between locations & increases efficiency overall!
