more Hello, my dear Wozier! In this update, I’ve refined how words are prepared behind the scenes. The study logic is unchanged, but the data now flows more smoothly and is less likely to leave you with an empty deck. There was a rare bug where swiping really, really quickly could make Wozi run out of words—this update sorts it.
• Made word preparation smoother and more dependable
• Improved the quality of the dictionary content
• Sorted an issue where Wozi could occasionally run out of words when cards were swiped very quickly

Hello, my new friend. This one’s for you. I know lots of products try to get you to pay as soon as you’ve downloaded the app, but I’d like to do things differently. You can try everything for three days without limits, then decide whether you’d like to buy the full version. There’s no subscription—you pay once, and it’s yours. Buy it during the trial and you’ll get 50% off.
I hope you enjoy what I’ve made for you!
