ok, lot of words missing

for the people complaining about the price, thats to be expected, theres not a single foreign language dictionary for free that I can find.

the app is ok, i use the spanish dictionary and there are quite a few words missing so if I don't have internet access to use google translate I have to wait to find out, which gets annoying. So please, One World, update frequently with more words. Also, every conjugation of a verb just says, for example with juegas; "conjugation of verb Jugar". It would be helpful if instead it linked directly to the root verb and highlighted the conjugation.

I'll give it a 4 or 5 star rating if you add a more complete edition of the spanish dictionary and make a few tweaks. Since I bought it almost a year ago there hasnt been any major update, a little disappointing.

English French dictionary & phrases

I have been using this dictionary for a few months and it has proved to be a great resource for my French class. The app has Spanish, German and Italian but this review is based on my use of French.

The basic dictionary has a good size database, sufficient for first and second year students. The translations include French noun genders, type of word and most entries have a few meanings. The free version doesn’t have a lot of usage examples but you can upgrade to comprehensive version from within the app or $10. Verbs are conjugated in all tenses like in one of those 601 verb books. Once the dictionary is installed you can lookup words from Safari with ctrl-click. I like using this when reading Le Monde online.

This update has a phrasebook with categories for traveling, customs, hotels, etc. There is a category called My Phrases to let you add your own. The button to add phrases is hard to find, check upper right of screen. All the phrases, including your own can be searched by keyword. An extended phrasebook is also offered as addon.

You can listen to dictionary words and phrases using text 2 speech. You’ll need to download the French voice if it’s not already installed on you Mac. I would like to see phonetic pronunciation in the future for when I'm in the library and don't have my headphones.

Overall, I’ve found One World Dictionary to be very useful for learning French.

love it

I keep the One World dictionary window open as I study Rosetta Stone since once in a while there is a word that I just can't "get". I would like to see all spellings used such as plural and tenses defined since it is difficult to find a meaning when you are in the dicitonary dark.
