Really useful app. I have only one, but serious complaint: the reference hyperlinks in the results are large and very sensitive, and more often than a care for, while I am trying to scroll down, I touch a link which takes me to another result - another word. I use a Samsung Galaxy S22+. Not sure how, but please address.

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.
