Fine as a dictionary, but the website does that. Has a weird dashboardy thing at the bottom of the page that is kind of distracting; it appears to have a notification but no matter where you click on it you go to the "install" page for some weather app. Also, the daily gift seems to have disaopeared. Kind of disappointing in the end.

So far, all good. 5⭐ @Sh Mo- If I understand correctly, it's awaiting your app selection to provide feedback. Most only support email for this but some may allow Telegram, SMS, etc. However, the Share Menu is far from perfect; it seems that even if email is the only option that will work, you're able to choose any of your social apps & if unsupported, it crashes without notice. One could easily think they submitted logs, a bug report, etc. but in truth, nothing but the app crashing took place.

Pretty good all in all. It definitely has the words I'm looking for and gives good definitions for all of them with examples and derivation. This is very appreciated! However as app, it's missing a couple of features like a built-in microphone with an auto search but all in all pretty good app and I would recommend this to others.

Good news--if you have the Google Keyboard enabled on your device, you can use its microphone to voice search in our Android app.
