LookUp: English Dictionary

What’s unlocked in this version

LookUp: English Dictionary App is patched with LookUp+ Lifetime, unlocking the app’s lifetime premium features in this updated IPA for iPhone and iOS. Install the latest modded build to access the unlocked Plus experience.

Words stick better when you meet them again and again, and LookUp is organised around that idea. Download the LookUp IPA for iPhone and use the English dictionary with the Lifetime tier of its Plus plan already active. The tweak is a patch of the original app, not a separate product.

About LookUp

On the App Store the title is LookUp: English Dictionary App, from Squircle Apps LLP. It is filed under Reference with Education as a second genre, rated 4+, and has been around since May 2014. The developer notes that it has been honoured by Apple as an Editor's Choice and was a Webby Honoree in 2021.

The core is a lookup tool. A word brings up definitions from the Oxford English Dictionary, thesaurus entries, example sentences, usage notes and recorded pronunciations. Translation is available into more than twenty languages, including Arabic, Chinese, Hindi, Spanish and Russian, which helps learners who think in another language first.

A second half is about retention. You save words into your own collections and then practise using flashcards, quizzes built on example sentences, speaking practice and interactive drills, all driven by spaced repetition. A new illustrated Word of the Day appears daily and can be placed as a Home Screen or Lock Screen widget. The developer positions the app for people preparing for exams such as the GRE, SAT, TOEFL or IELTS.

What the LookUp tweak unlocks

• LookUp+ Lifetime features active from the first launch
• Full dictionary and thesaurus with audio pronunciations
• Illustrated Word of the Day
• Translations in 20+ languages
• Spaced-repetition quizzes and personal word collections

Requirements and latest version

Per the changelog, this IPA is patched with Lifetime Plus, so no subscription prompt is needed. Be aware of the platform floor: the store build requires iOS 26.0 or later, so it will only run on an iPhone updated to that release. The most recent store update made the Explain function faster and more accurate and fixed a crash when a word was pronounced through Siri or Shortcuts.

To build your vocabulary without a paywall, open LookUp on builds.io and tap once; the IPA arrives on your iPhone and no PC is needed.
