AFAIK it's the best of its sort, but I've used it a few times (not for a few years though) and I don't think I've ever found the actual font. Though of course it finds similar fonts which sometimes can be enough.
True.
But I guess we have to accept that fact that the app will only ID fonts that are in it's (premium paid) DB.
I always dreamed about an alternative that does the same visual identification but matches closest-fit to a database of free opensource fonts.
That would be awesome because fonts can get expensive, especially for websites and pay-per-traffic pricing!
