The Compass App

If you are walking, stop, then turn around in place, it will never know you did it. A compass is required in that situation.
Most in-car nav systems not only include a compass but also have wheel speed sensors. It not only helps counteract position error while stopped (your calculated position tends to wander a bit due to atmospheric conditions), but it also helps in situations when you're dealing with an obstructed view of the sky, like in a tunnel, under heavy tree cover and in urban areas.
My wife's car continues to reasonably correctly plot its location even in parking garages where there is no GPS signal at all.
WAY overdue.
Compass app v. compass - subtle but important difference.
lol um id venture not
why not use a real compass that doesnt rely on a batt. as a hiker, there is no way id use the iphone for navigational purposes. not to mention, trail maps arent even part of gogle maps anyways
But there are trail map apps.....Also what if you were to not have any gps signal or service in the middle of nowhere.....Compass app to the rescue!!!
They should just add it to the maps app and make it work with other Apps that need to use it or can make use of it. I don't think I will ever click on the icon just to see a compass. Another Icon we won't be able to remove just like the contacts app and the useless weather app that gives wrong readings all the time.
Apple should give us a choice to be able to remove useless apps or apps we don't want or use.

I'm guessing that you have a brain which should have the ability in that situation to work out which way to go... otherwise walking might not be the hobby for you...
first please learn to speak English... second my car has it built in and with a map over top with which it shows which way to go, and having the use of my eyes and brain I can read a map, and anyway within 50-100meters it knows exactly which way I'm going.
the original statement was "A compass is pretty much a necessity for any turn-by-turn navigation applications." its not.
if you want to stand outside and spin in circles and watch the map rotate, thats up to you.
lol until the batt gives outtheeeeeen your ****ed
hahahaha hopefully you can then use the teleport app that will be included with next year's phone...but then everyone will complain about that one too.
Seriously? You actually think a GPS is a replacement for a compass (or a brain?). Ok, but I'm not following you off trail...
Stop and think about what you are saying and you have the answer as to why a compass is needed. That's exactly what dukebound85 said about his Garmin. It does NOT show orientation. People that need directions don't recognize their surroundings - it's called "being lost".
"You're in a twisty maze of passages, all alike."
Some people need to go back and "earn their navigation badges".
Just drag them to the last page. They added 2 more pages on the end for you in 3.0
But the compass isn't needed. It could be a nice addition, but it isn't a required part of a functioning GPS unit. If I'm lost at Point A and I want to get to Point B the best route between Point A and Point B doesn't change depending on the cardinal direction I'm facing. I mean, if I'm driving from San Francisco to Los Angeles and I get lost in central California my GPS is still going to tell me to go South regardless of whether or not I'm facing NSEW at the time I ask my GPS for directions. If I want to get directions to the nearest Wal-Greens the iPhone would tell me to go one block North and one block West of my current position. None of that changes depending on what direction I'm facing when I ask for directions.
Lethal
Imagine an iPhone-ised version of Stellarium with realtime directional rendering (star pointer)...
I bet Celestron wouldn't be too happy!
a compass is not needed. your direction is determined by movement. a compass is a nice bonus feature but in no way is it a necessity for turn-by-turn navigation.
Magnetometers cost like 3 cents and they provide for better direction tracking and auto map rotation. There's no reason NOT to have a compass in a turn-by-turn navigation device.
That's why I said they are "pretty much" a necessity. They cost very little and improve the user experience. There was nothing "silly" about my statement.
In no way was I saying "turn-by-turn should be 3G S only" or anything close to that.
