### 3/5 — The function of add a note is useless

*2026-08-26*

I’ve been using this app for a half year. For recalling my memories, this app is best ever.

I’d like to ask one modification for this app. When I add a note in every words, it is sometimes vanished maybe after I use sync button. Can you deal with this defect?

### 1/5 — Fake "Free Trial" – No Warning, No Refund, No Support

*2026-08-12*

The app shows a button offering a "2‑week free trial," but if you've ever used a trial before (even years ago), it charges you immediately without any warning. I clicked in good faith and was charged right away. No notification, no eligibility check, no heads-up.

I contacted support – no reply. Apple refused a refund because the issue is with the app's misleading interface.
So the app gets to show a misleading button, take your money, and ignore your requests.

My advice: If you have EVER used this app before, do NOT click any "free trial" button. You will be charged instantly.

WordUp – please fix your interface. Warn users before charging them. This is not how honest apps behave.

### 3/5 — Best vocab learning app

*2026-07-26, version 17.3.4280*

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

### 5/5 — Perfect app ever

*2026-07-18*

Superb to learn English

### 5/5 — So cool

*2026-07-16, version 17.3.4280*

### 3/5 — Not bad

*2026-07-14*

Need a way to sort my vocabulary by most recent

### 5/5 — Iran

*2026-07-14, version 17.1.3416*

Hello,

I’ve been using the WordUp app and I would like to invite my friends to join using my referral link or code, but I can’t find any “Invite Friends” or “Referral” option in the app. 

Could you please let me know how I can get my referral link and earn hearts when my friends sign up?

i live in iran and is so expensive for by worldup pro
Thank you!

### 4/5 — Word ranking feature

*2026-07-13*

Very helpful app! I like the way to learn new words through English, helps me understand and remember them more efficiently.

One feature I really liked was that, when you search for a word, its rank on your world map will be shown in the popped-up list. This way I can learn the new words that I know from other sources selectively, only focus on those with high rank.

Unfortunately after my last update, it disappeared :(
It would be really appreciated if you could bring it back!!

### 5/5 — Good
