Love the dictionary but this app is such a pain to use. The ads are whatever, but simply scrolling the page for a word is a hassle because the screen is so sensitive that it'll tap on any highlighted word and go to that page instead. Like, I'll be looking at the definitions for any given word and if I'm not careful enough when scrolling I'll accidentally tap on 'noun,' as if I need that definition. Given that the thesaurus is nothing but highlighted words, it's like a mine field!

dude like ... T F ! ! I'm sure I'm not the only one.. It's been over a week and the App force closes every time try to open it. EVERY single time. And have a paid subscription. Which about to sadly unsubscribe from. There hasn't been a update for the longest. I can't be the only one with this problem. But nonetheless. I have to unfortunately find another app that doesn't force close Every single time.

I mostly liked the app, and have recently discontinued my subscription. I found it terribly irritating that many words I would search for were not found within the app, but a simple Google search gave me the definition with no problem. The words were unusual, but not slang, and it really made me wonder what I was paying for in the app
