Why PLT was Created

So, what is the secret to creating a tracking app? It is a labor of love. When my daughter was travelling alone back to college and her car broke-down. There was no way to know where she was. We talked until police showed up but until then not knowing exactly where she was, was unnerving.

Solving a problem was the basis for the creation of PLT and advancements in technology has made this product viable to this day. Modern solutions, interesting elements, and our unique approach to details make this app worth owning. Knowing where your family and friends are, is peace of mind.
