Yes, definitely agree. I feel the latest UI for iPhone alarms and the timer are a good example of how inconsistency in button placement can be confusing.

When a timer finishes, you get a large button at the top for Stop, and a smaller one at the bottom for Repeat. When an alarm goes off, the Stop button is the small one at the bottom, and the larger top button says Snooze. Very often I find myself repeating a timer instead of stopping it.
