What's New in LookUp

October 8, 2026

We've changed the underlying architecture of the Explain function to make it faster and more accurate, with clearer explanations, connotations and usage examples. Fixed a crash that could happen when pronouncing a word with Siri or Shortcuts.

Used to be amazing but

Then everything went behind a subscription, what a shame

A Museum

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.

Very Mixed Results

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.

Traduction en français

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

Do not bother

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
