### 5/5 — A Museum

*2026-06-28, version 12.1*

Using LookUp is like stepping into an art museum for words. Its images and typography are bright and welcoming—nobody needs a map to navigate—and I have frequented its galleries for many years now. I have curated my own collections from books I’ve read, loving some and saving others.

The Notes feature has allowed me to make my own contributions. I can record where I first stumbled across each new word. Gaskell, Elliot, Wordsworth, and Keats are a few recent authors and poets that your app has helped me navigate, and they also walk its galleries.

I am curious to see where the creativity and curation will go next.

### 3/5 — Very Mixed Results

*2026-06-17, version 12.1*

I think the app is great. The content and presentation are great. I runs flawlessly on my iPad and my iPhone. I have three different Mac computers. It errors every time I try to open it on all three machines. It has been this way from the start. I’ve written twice to the developer, Squircle Apps LLP. It has been over a month and I’ve never received a response. An online search indicates this is a known problem. The app needs to be fixed or the developer needs to quit advertising they support Mac. It is a lie.

### 1/5 — Traduction en français

*2026-06-06*

Incompréhensible. Toutes les langues les plus,utilisée sauf le français. Et ce depuis des années de demande au développeur. 1 étoile donc.

### 1/5 — Do not bother

*2026-05-22, version 12.0.11*

Everything is behind a paywall. Even their “free” word of the day is paywalled after 2 days. Will be switching to a different word of the day app. One that isn’t so greedy

### 5/5 — Best Dictionary App

*2026-04-20*

Five stars! The UI is clean, but the real value is in the Word of the Day. It’s helped me expand my vocabulary naturally without feeling like I’m studying. Highly recommend for students, professionals, or anyone who just loves words!

### 5/5 — The absolute best

*2026-04-03, version 12.0.10*

This app was obviously created by somebody who loves etymology and vocabulary. This is a proper, fully featured dictionary and thesaurus, but the way that everything is presented is absolutely amazing for exploring the language and learning something new every single day. I have the widget added and the notifications activated, because it’s always so much fun learning new words. The way that they are presented is memorable and thematic as well. Thank you so kindly for this app.

### 1/5 — Very disappointed

*2026-03-31, version 12.0.10*

I was disappointed to see that almost every feature on this app, like the tests and review quizzes, were locked behind “LookUp+.” I eventually settled for just using the word of the day widget, and it worked, but after two days, it expired, and became locked until I purchased the upgrade, meaning I could do literally nothing, and the app became a huge advertisement for “LookUp+.”

### 1/5 — Deleting

*2026-03-20, version 12.0.10*

The app manages to somehow keep launching itself even though I have removed it from login items. I have contacted the developer about this but have had nothing back after three weeks. I find the apps behaviour very irritating so will be deleting once this review is submitted.

### 1/5 — Free version bad paid is $10

*2026-03-18, version 12.0.10*

The free version is a disgrace. Like 2 times it will give you the word of the day for free and that’s it. After that better be ready to pay 10 bucks just to get random words once a day.  
In addition, this app pretends like it has other features, but you have to freaking subscribe. All in all this app is somewhere worth the money or your time for the free version

### 5/5 — Excellent Dictionary

*2026-03-07, version 12.0.10*

And stellar support! The issue I had on my iPad mini was resolved really quickly
