I keep the app open all the time

The title says quite a bit. I have an okay vocabulary (scored in the 95 percentile on the GRE for the language section), but abysmal pronunciation. The M-W word pronunciation is a must for me. Plus, I diligently look up any words I'm not certain about when reading. This app makes vocabulary learning easy. I use the free version, so not every word I look up is available, but most words searched for are listed in the M-W free app. I thoroughly enjoy their word of the day, and vocabulary games. I'm a fan of their website and videos too.

Great app

Very descriptive! Very fast, as I'm entering the beginning of the word I'm searching for words begins to appear with the beguine of my searched word before I even finish entering the rest of the letters of the word I'm searching for, I'm then able to click my searched word fast and receive the definition of it quickly, as I'm studying, doing my homework and reading. Especially when I am stuck in my reading and not understanding what a word in the text is about. Very helpful app, and very efficient ! Love it!! Thank you WD!

Fast and simple, destined to impress!

I spend much time reading the works of authors who have come and gone long before this millennial started reading. As a result, I regularly find myself in need of a fast, simple dictionary that I can use wherever I happen to be studying. This dictionary does exactly that. It has just enough features to be useful, while avoiding the clutter of some of its competitors. I would highly recommend this app for anyone looks for a reliable, fast dictionary on the go.
