Perfect tool for exploring my innate passion for language. The customizable bookmarking feature is **fabulous**. I also find the audio pronunciation feature invaluable! I'm an avid reader, but there's few things more embarrassing than knowing how to *use* a word in conversation yet pronouncing it incorrectly! I love this app. I can't do without it and cannot even offer any suggestions on how to improve it. If you love language, or simply need a hand on spelling, grammar, pronunciation, or syn

This was a great app when I first downloaded it three phones ago. But these last two years, it will often fail to open, even when it's closed and reopened numerous times. Sometimes it just locks up when swiping back from an article. The content is great, so it's frustrating. I've never had such unpredictability with an app. It was five stars when I first got it. Please do some maintenance.

I'm not impressed, first it requires you to create an account. Next, it doesn't integrate into the system, at least not from my experience. I'll be un-installing. Edit... By integrating into the system, I mean into the keyboard and/or when you select/highlight a word and the copy paste etc options pop up, there is no option to to directly go to the dictionary app. I also tried the Oxford dictionary and though it has its own problems, that app did what I described.

Good news--you do not have to log in to use our app. Creating a The Free Dictionary account is completely optional. You can use the magnifying glass in the app's top toolbar to search without signing in. Thank you for your feedback. I will pass it on to our development team.
