Excellent App, but could be a little better – DataMan Pro Review

It shows what % of data you've used and how many days are left in your billing period. I think it would be a lot better to show both values as percentages. That is, instead of "41% of data used, 12 days left" say "41% of data used, 33% of days used" That way you could easily see how you were doing.
