No more push notification??
My phone is currently 17.5.1 And since quite a while ago the app's "notification per day" won't work anymore. I didn't receive any notification at all. Is it because this is a pay function now? Please advise. I tried the free trial (7 days) version...but too no avail. Want to make sure it's not a bug issue before I pay for the app. Please advice. Thank you.

Upload our own list
I love this app! It is really useful in reviewing vocabularies. However, I do hope there could be a “upload” button. Therefore I can upload all the vocabularies I need to review without needing to type them in one by one through the search bar. Thank you!

Great app for learning vocabulary
This app is great for learning new vocabulary. The format is easy to use and aesthetically pleasing. The repeated learning of a word helps me because I often forget the definition of a word after the first time I read it. I've already learned many new words and I’m surprised that more people don't use this app.
