8 of 25I look up “ camping “ the app returns a result of “ damping “
Like others have said, the ads are annoying but what mainly stops me from using this app is that there’s not option to file or favorite select words for reference later. As a writer, this would make for an incredibly useful tool.
This app recently updated and users can no longer view the previous WotD. I have been using this app for over 10 years and I have accepted, willing or unwilling all of the changes. However, this most recent update that removed the ability of users to view the previous days WotD is unsatisfactory. Please add back that function!
I can deal with a reasonable amount of ads, but now they’ve added ads with audio and basically no way to simply mute it or have the entire app muted. It’s intentionally obnoxious and unusable now.
The new app design is absolutely horrible. I can't find anything. Not a good look.
I used to love this app, but the fact that human beings don’t even edit the product, it SUCKS. Word of the Day, for example. Used to love. First I found it odd that instead of putting the actual book that the WotD came from, just says “Literature”. Any logophile is going to want to know what book the quote is from, duh. And a human would know that. Then, I started noticing some of the “examples” are clearly pooled from an enormous base of data- as several say things like “Here’s me using SWIVET in a sentence” “Today was vocab day and I drew a blank on SWIVET” (These both came from “literature”, but I can promise you that IF these sentences actually came from any book, the book is NOT what any person would consider “literature”. This is only a couple of examples of how I know AI is now in charge of the production of the newer material in this app- either that or a very uneducated child under the age of 12. Also, I try to look up relatively normal words like “sonder” and it pretends the word doesn’t exist. “Wonder” “fonder” anything but the word I need!
Many features were removed when an overhaul happened around 2024, perhaps earlier. Now it sucks. It’s just a web app that resides on your phone taking more information than it ever did before. Deleting.
Get rid of the ads as I paid for it.
