GPS tech (Garmin, Hammerhead, Wahoo, RWGPS, etc)

I looked at yours when you mentioned it a couple of years ago but I think it doesn't do power, is that right? I think that's why I didn't use it.

Agree that the car apps / Google are not great for cycling.

The ones I have on my phone are:

• rwgps, which I pay for,
  
• osmand, which I paid for a small one off amount,
  
• bikecomputer pro (ditto), which is the best all round alternative I've found for my needs as it does power, and it's designed for cycling, - cyclemeter, which is very good for intervals.
