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.

I don't normally mind ads, but the ads I've been getting from the app lately are blatant full screen scareware malicious ads that'll definitely put something on your device. Wish they screened who they have advertising on their site. Besides that the app itself works great. Loved being able to speak the word I'm trying to find if I didn't know how to spell it. Bummer.

i accidentally updated (downgraded) the app, and how the voice capture is horrible and inaccurate compared to the original version ive had a few years ago. i mainly use this to get the correct spellings with voice input, but now it's mostly useless because it often cannot detect the spoken words correctly anymore.
