iTrail now works while in the background ! Whether you
take a call, listen to music or surf the web, iTrail will continue
recording your location. This will work for all users of iPhone 4 and
3GS running iOS 4.
But, please be aware, continued use of GPS running in the background can
dramatically decrease battery life.
All your workout data has been recorded you can now see your progress
on a map courtesy of Google and plot you sped and altitude versus
distances on graphs. To do this simply press the My Trails button in
the bottom tab bar. You will then see a list of all your recorded
trails, select one, and you should then see its details screen, like
the one on the blow. Here there are a number of button for plotting
graphs, viewing maps, continuing and deleting the trail.
Here is a graph showing your speed plotted versus the distance travelled. The maximum speed is shown on the top left.
This is a graph of altitude plotted versus distance travelled.
This screen shows a Google map of the route taken on this trail.
