Newbie oldster riding a lot and learning a lot. I've gone from Garmin dislike (unnecessarily high tech, distracting, and too much money) to considering purchasing one ($350 isn't much more than decent HRM plus cadence computer).

Then I realize that I should at least ask if there are any smart phone apps that would make one a practical alternative. And would you need to consume lots of data transmission charges?

I currently don't have a smart phone but may be upgrading to an Android phone soon.

Thanks
