A great dictionary but the latest version of the app has a couple of bugs: it frequently crashes, especially when entering a word, and seems to automatically transfer your last text message into the search window. Needs work.

New feature includes copy protection bugs

Was my favourite and also the most expensive app on my phone for a long time. With the latest version, it started occasionally popping up the message "Run in safe mode!". Then it started crashing. Then even when it wasn't running it started giving me a notification saying "I am a software thief!", even when it wasn't running. That was a bit insulting. When I next tried to sync my phone it couldn't be installed due to an unknown error.

Otherwise it's very fully featured and the catalogue of audio pronunciations are great for resolving arguments without anyone having to learn IPA, so I'm still giving it five stars. (That rating will decline rapidly if the false positives on the copy protection don't go away soon.)

A extremely complete portable dictionary

I have a number of linguistics related apps and until I loaded this one I had always managed to find a shortfall. This is not the complete OED & doesn't claim to be but it is extremely good. I have also found ( unexpectedly) that the sound feature is a very useful. It is not inexpensive, however it provides more features & flexibility at a lower price than the hardbound printed volume, and fits in a pocket! This would now be my first choice recommendation for an English language dictionary app!
