Where I live (US East Coast), the weather can feel dramatically different depending on the humidity. Relative Humidity has always felt to me like a poor way of measuring how humid the weather will feel. For example, 50% RH at 84ºF will feel lightly humid and generally pleasant, whereas 50% RH at at 97ºF will feel like a swamp. The dew points at those respective points - 63ºF and 75ºF - do a much better job at immediately conveying how humid the air will feel.
Dark Sky used to show hourly dew point graphs that you could browse throughout the week and see when the humidity would break (or return). Apple Weather does show you the dew point, but only when you select a point on the RH graph. So to track the dew point over the coming week, you basically need to drag your finger over each day's graph and observe the changing numbers.
I think this is probably just due to the lack of general awareness about how dew point is a more elegant shorthand for "absolute humidity" than any other weather metric currently in use. I hope there will be more of us in the future!
