salad-dodger, that's like the 'wimmin' app you can get for a SatNav*:
- After passing a turning, it announces "You should have turned there".
- If you ignore its directions on more than 2 consecutive occasions, it announces "Do what you like then, if you must know better" and then shuts down.
- It generates random, "You knew I meant left" announcements after telling you to turn right.
- Every 28 days it gets hysterical and sulky for a couple of days.
But it looks very pretty.....
*actually, you can't!
