User Reviews

WordUp is praised for its effectiveness in expanding vocabulary and for being easy and enjoyable to use, with a strong daily review routine and broad word coverage. However, recurring concerns include robotic AI voices and questionable images/definitions, instability after updates (errors and UI glitches), premium membership issues (unreflective charges or access problems), and inconsistent content quality. Overall, it remains a powerful tool when stable, but users want reliability, better content accuracy, and smoother premium access.

I bought lifetime access. I like the most common words lists, best ROI on learning, cool graphics although recently the AI quality got worst. Unique context and use case when teaching each word with simple definitions. After using it for 4 months, I noticed it’s all recognition of words only. It doesn’t have other ways to strengthen that learning. I vibe coded a supplement app using ai to fix this gap. It was so easy! They can easily use ai to add more features. Data is inconsistent! Many times I load and reload and come back to different or same renew words. My saved lists don’t save. There AI is extremely bad and doesn’t have the context of the app. None of the chats with the people in the app matter or help at all. I never use ai to even clarify the difference between to words. I have to go to other AI like ChatGPT or Claude to explain
