  • Love Love Love this app!

    By Viclys
    I use it daily. Having access to definitions at a push of a button. Also, I enjoy the games!
  • Aggressive ads

    By kota.b.t
    I use this app all the time and I’ve had it on my phone for a very long time. Just now an ad popped up for family guy/rick and morty with FULL volume. I have never had an ad with noise pop up on this app, or any other app, without me doing something to make the volume turn on. This was completely unprompted. On top of that the X to close it didn’t appear for several seconds so I couldn’t exit out and of the loud ad. I pushed the home button on my phone instead but the noise persisted despite the app not being open anymore. Unprofessional and too aggressive.
  • My go-to-app

    This app is easy to use with a nice interface and simple set up. I love the speech-to-text search option.
  • Best App Ever

    By Singer127
    I love this app I love to read and this helped me a lot with understanding words. It also helped me with homework I recommend this app to a person that has a hard time understanding words in a book or someone who needs help with homework! This app really helped me a lot and I recommend this app to you it’s just like a dictionary but on you tablet or phone!
  • Love it

    A staple to my writing-
  • Simply not as good as it could be

    By PixieSparks
    Riddled with adverts that cannot be easily closed, often with the close X being directly over the link to app or page. Constantly bugging out by way of freezing or shutting itself after an advert pops up (which is often). Adverts are almost always religious, which while I support anyone’s right to practice religion, I don’t think my MERIAM WEBSTER dictionary app should presume everyone using it is Christian. They are basically the “name brand” dictionary, I expect better.
  • Greasy app

    By Sizzler23
    Easy to use. Love the pronunciation function.
  • Quintessential Dictionary App

    By christopher duder
    Fantastic. I use this app everyday. Love how easy it is to use. Games are a nice addition.
  • Great App

    By Honeymel71
    I have really liked this Dictionary app. I love that it gives older definitions, as I use it to look up words I read in the King James Bible. It gives me insight to the scriptures and helps me understand them better. I love that it gives the origin of words. I haven’t tried looking up much modern slang, but saw that another reviewer said that it is updated regularly, so, I will probably check that out, too! I had tried other Dictionary apps, but really have liked this one best. Thank you for a great app!
