What's New in LookUp

13.0.1

September 14, 2026

LookUp 13 brings new ways to build vocabulary and look up words through the latest technologies in iOS. Extra Large Portrait Widgets bring the Word of the Day widget in their full glory. With Siri you can now ask it to define a word in LookUp, or surprise you with a random word from the app. Local Modals and Private Compute on the iPhone and Apple Watch ensure a private learning experience that’s contextually rich. New ways to LookUp: Scan Words: A completely revamped Scan Words feature lets you point a finger at the word you want to look up and get its definition. It also picks difficult words in the page. New Reading Mode: We’ve updated the reading mode to work as an audio companion while you’re focused on reading. The new Reading Mode let you speak aloud a word and gets its definition from the Lock Screen. Get Definitions using Siri : You can also ask Siri to search for a word in LookUp and it does the honors. New ways to Learn: Introducing Interactive Flash Cards: Interactive Flash Cards have you define words through voice input and grade you based on your closeness to the actual definition. This Foundation Models powered feature is a great test of your ability to recall word definitions. A completely new conversation mode: Conversation Quizzes are 10x more fun with a new conversation learning mode that empowers English learners to not only recall definitions but also understand the context in which words are used. The app now shows a natural conversation between two people, and once that conversation is done, it ask the learners about what worked for them. Redesigned Learn Tab: The Learn Tab has been redesigned, keeping in mind these amazing new learning modes, to better serve learners through guided quizzes, picking something new for them every day. Siri : Ask Siri to give you a random word, and it shows a beautifully crafted illustration, hand drawn by our editors for you to remember a word. Extra Large Word of the Day Widgets on iPhone: With the latest extra large format, you can now shuffle through old Words of the Day in their full glory.

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
