I've been testing out a few apps either this morning or when walking. Here are some comments:
- The free "navfree" SatNav app stores maps and StreetView photos on your phone (using up 500Mb) works well - and you can hear the directions ok and unlike other cycling apps such as MapMyRide or Sustrans you get a 3D view with the map oriented in the direction of travel. Also the map is very clear and can be seen without reading glasses!
- MapMyRide provides basic maps but does not seem to move the map as you travel along (unless I've not discovered this setting) and they always point north. The advantage of MapMyRide is you can follow pre-planned routes and record tracks.
- Sustrans works better from a navigation point of you and you can download good quality maps showing individual buildings and the map moves as you cycle - although are always oriented north.
- GarminFit is another simple tracking app, but you can only see the maps afterwards!
I'm also getting a Garmin Forerunner 110 GPS watch with a heart monitor for my birthday to use mainly for running. My wife and I said we might do a half marathon with our niece in Sept. I'll probably use this for road bike trips for a bit, mainly to give some info on heart rate etc - but its main use will be for running. My heart rate tends to be quite slow at rest (50-60 bpm) and goes up to around 140 bpm after about 15 mins of running, which is about 85% of my max recommended heart rate for my age (based on 220-57). I want to train safely for running so the monitor should be useful. Also you can upload your details from the watch to the Garmin Connect site to see your route and stats. I doubt if I'll take the watch to Land's End as the battery only stays charged for 8 hours when tracking, and I'll be able to track with my phone anyway.
