Its hard to rave too much about a one-trick pony, but it does what they say it does, consistently. Ive been using it for years, and Im impressed by the frequent updates.
I should note that the ads are not at all intrusive on the free app, but maybe Ill upgrade to the ridiculously cheap premium version anyway because it now strikes me as incredibly miserly not to do so.
