This app used to be great... 5-stars great. But ever since they revamped it, it's been very glitchy. I receive double the amount of notifications and the pages refresh twice or more times before loading. I have tried uninstalling and re-installing it and it's still glitchy as hell. I really don't care for this version at all. I hope the issues will be addressed soon, otherwise, I'm going to have to find a different dictionary. Frankly, this current version is more trouble than it's worth.

We know the pesky push notifications are causing consternation! Our team is working on it and we'll push out an update to the app when a fix is ready. Thanks for sticking with us!

Wow. After the update the whole app changed and it's no longer properly functional. I deleted all my recent words but they all appear again once I reopen the app. So basically we can't actually delete words. Another issue, when I'm looking up a word in the thesaurus section it takes me to the dictionary. I have to click the dictionary tab to "reset" it first and then click the thesaurus tab. It also lags. The old version was so much better. I really don't like using this app now.

Thank you for taking the time to share these concerns. We are sorry to hear them, but your notes help us see where we need to improve. One small thing that may help: It looks like you're using an outdated version of the app. We'd love to hear if an update fixes your problems!

Edit: Thanks for the response. I agree it is an unreasonable expectation to have every single word. Keep doing your best to add all words. I liked the interface so much I paid for the ad free full version as I found it very easy to use when reading postgrad materials. The UI is solid and simple and easy to use as well as the app has some nice features.

Our fantastic team of Lexicographers is hard at work conducting robust linguistic research, writing new entries, & editing or updating existing entries: https://www.dictionary.com/e/new-dictionary-words-summer-2021/ . But, as you can imagine, with the entire English language to wrangle, this is a never-ending job; we'll keep working on it Thanks!
