Timed dry custom time doesn't work
Hip Shot needs 2 improvements

I set the default to 85 minutes as a test and even after saving, exiting the app, etc, when I hit the Timed Dry button it gives me 30 minutes.

No need to remember how long each cycle is!

I use this app every time I do laundry (which is too often). Instead of remembering how long each cycle is, I can simply press a button for each of the normal, permanent or delicate wash or dry cycles. In response to the comment that Timed Dry does not work - he/she is incorrect. Setting the default Timed Dry to 80 minutes doesn’t change the slider, but will count down from 1:20 (i.e. 80 minutes). The slider is for single use and is limited to 30 mins to maintain fine control.
