Great app! Loved how easy it is to use, and the notifications on other iOS devices is killer!
So far Ive use the meat range on fish, chicken and hamburgers. In each case, the temperature has been spot on, and only taken a few seconds (from not being used, aka the Range is at room temp) to get an accurate reading.
The only minor quip I have is at the moment theres no universal setting for fish, but I suspect this is because seafood has different temp ranges depending on the type
