Needs a white selector wheel
Update is nice BUT the black/grey on grey selector wheel is really hard to read and out of place with the rest of the color scheme. Please change to a white background wheel, then it gets 5 stars.
Update: Developer responded to my request very quickly - now the selector wheel is legible! - excellent app now.
