Dictionary apps are generally worse than one would think, for some reason (most developed by MobiSystems). This is easily the best of the bunch. I was using AHD, but the ads were so intrusive, subscription eye-poppingly expensive, and the app itself like something from 2010. I'm paying for the ad-free M-W now for a very reasonable price and am very pleased. The app feels modern and professional. Whatever you do, don't just Google words.

After I upgraded and am currently paying for my subscription, it is still showing ads. Also, fix the sensitivity of the text, many times when you are reading the definition of a word and scroll down, you accidentally click on a different word, and it takes you away from the definition you are trying to find to some other word's definition which is really frustrating.

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.
