When I originally obtained this app, it was great. Now, it won't even recognize that I am connected to the Internet when I obviously am. That means that audio input and output won't operate at all. Without voice input and pronunciation output, the most important funtios for me are lost. One of my favorite purchases has become nothing but a source of frustration. Update (08/12/26): On the advice of M-W, I reinstalled the app. Now it's working as it should.

Great app! I've got a suggestion for the Games section: please add a dedicated IELTS/TOEFL prep zone right there. Many test-takers need targeted academic word lists, quizzes, and spaced repetition exercises to build active vocabulary. The current games are fun but general. Adding this feature would make it an indispensable study tool for millions of global learners. Please consider! 🙏🏻

I have only noticed two problems: my keyboard will disappear whilst I am typing, taking me to a definition I probably wasn't searching for; and every so often, the app will nag me to subscribe to a monthly plan, even though this is the premium, paid-for app. Other than that, this is a perfectly usable dictionary app.
