The free dictionary by Farlex

Farlex free dictionary is a good site, but they refuse to admit their errors. If something on the site isn't working right & I ask for help, after a lot of trouble trying to get some help, I am always told that they're working on it, but then send an email. The problems are not solved for me. I'm playing as a registered member of The free food for the hungry program & I'm in 2nd place in my city. The "mismatch" word game uses the same words redundantly. The words used today i have seen at least 2 other times this week, and more before that. The green spoons by my name have still never been added and i have 8k or 10k points. i have tried to get my profile picture put up for 2 months & it gave the same 2 excuses every time it wouldn't work. there are too many bugs. I liked the app before I registered for their free food for children program, but with all the bugs and never shown the icon that i haven't got to see them, i feel that i'm wasting my time doing that for charity.

Totally Worth Getting!!!

I have had this app for about a month now testing it out. I love it! If I read something and want to know if fuller meaning of the word, all I have to do is copy it and paste it into the app. But that's not all this app gives you! I love knowing where phrases come from or the history. This app includes something for this. There's all kinds of additional information you get besides dictionary. And you can keep the extras that you like, and take out the ones that you aren't going to look at in the settings. Now my us husband even has the app and loves it because I was always sharing with him things that I found on the app. Thanks for creating such a good program. Keep up the good work!

A complete dictionary

I used to have another dictionary app on my phone and were always disappointed of its shortcomings until I found this awesome app. The Free Dictionary is a complete app and very helpful. It uses more than one dictionary for the meaning and includes the thesaurus. It even has translation and "view in context" sections for user's references. Its thorough typing suggestion is another big plus. I am very happy with this app.
