In Kananaskis country in Alberta, Canada, at the moment, there are lot of celullar dead spots. And when I found a part of trail that has signals (1 bar, 2, and so), every time there's a reception, automatically I reach my phone to see if there's an internet feed that I can show where am I now? If there would be a population of a million per year visiting these mountains in Kananaskis, these giant wireless phone providers would add or expand their coverage. They even would put to cover the deeper valleys if they need to, but that's just my business point of view.
Using an iPhone 5C, no GPS for offline mapping, so I always needed a cellular signal to use the trailforks app. Let me share this from http://www.wilsonamplifiers.com "your cell phone is basically a glorified calculator that takes photo" without a reliable wireless signals.
Just found a benefit from bunch of what we can do using the trailforks app by capturing every screen, shall I call it "Where Am I?" feature and when you click that yellow arrow indicator, this will lead you to where you are. And by that, you can capture that current screen and use it when you're adding your ride log with the image and time.
At the end, this could help a bit for my future rides on what part of trail I would stop to check cellfone reception.
