Fun, easy to use, and great for learning!

I’ve been looking for an app to help me grow my active vocabulary and this seems perfect! I already have a broad vocabulary when it comes to understanding what I read, but when I write my brain struggles to come up with the same words in the moment I want to use them. Being able to use words in context while solving puzzles is exactly the kind of game-ified applied practice I was hoping to find! I also love how easy it is to switch between difficulties, which is something the previous vocabulary app I was using lacked. With this one, I started on normal mode but switched to hard mode after a few games, which feels like the perfect level for pushing the edge of my comfort zone. I haven’t tried multiplayer yet, but the solo mode is excellent! I definitely recommend checking this one out! 😁

The only small issue/suggestion I have as of now is that when I tap on a word to bring up its details panel, such as on the word of the day, I don’t see the button to save it to my favorite words. My phone is on the older side and has a shorter screen than most new ones, so it could be that the button exists and just isn’t visible on my device; I’ve had that kind of interface compatibility issue before. Still, if there’s a way to make it adapt to a shorter phone screen that would be great.

Response from developer

Thanks so much for this very nice review! I noticed you going ham on the leaderboard haha so I released the next update early for you before even preparing the app store image and videos for it. I hope you like it! You're totally right about the button for favoriting words in the details panel. I've already made the change on my local version, which will be included in the next update shortly (you'll also be able to add the word to any collections there). If you have any more suggestions for the app, you can go to Settings -> Suggest a Feature (or -> Report a Bug). Additionally, I will enable the ability to provide feedback on the contrastive images and nuance information shortly. Thanks for playing!

Builds Vocabulary and Fun

Gets better and better with each update. Not your average crossword puzzle, but rather a puzzle that builds vocabulary with intermittent repetition of missed words. It’s different, and I really like it.
