I run cyclemeter and keep the phone in my pocket. But when I wanted to start getting a visual I opted for a regular bike computer. You can get mounts for the phone, sensors that feed the phone and also run map program to help with routes but with all that after a while your phone will run out of power. Now we're looking at juice packs etc. It gets to the point either just get your normal bike computer for between $39-$79 (you can get cadence and wireless for $79) or pop for the big Garmin at $500
