Fantastic app

A Swiss Army knife of unit conversions! Allows customizing what units to convert so you don't need to scroll through long lists of possible choices. Currencies update automatically. Developer responds to feedback. Five Stars!

Response from developer

Dear User, Thank you for your feedback and for using our app! Denver (Mountain Time) is indeed included in the list of time zones. As a major timezone, it is set as a favorite by default (with a star) and can be found at the top of the list, between Chicago and Los Angeles. This might have caused some confusion since it does not appear in the alphabetically sorted list that follows. We hope this clears things up! Best regards, --Shift Unit

Denver and Mountain time missing from Clock section of app

Great app! For some reason Denver and the option to choose Mountain time is missing in the huge list of cities in the Clock section of the app. As far as I can see, there’s no way to choose Mountain time.

Almost

Great app, if one only could select favorites for other unites besides currency only.
Please add that feature and this app will be a 5 star app.

Almost the only app deserves 5 stars

Shift unit is a tremendously useful app, mixed with neat design and all of that is free. A real 5-Star app.
