Verdict
Reviewers repeatedly complain that offline access is broken or missing after updates, which undercuts the main reason someone would buy a dictionary app instead of using a website. Performance also slowed down for some users after a recent update.
Best for
Someone who mostly has a data connection and wants a comprehensive Longman-based dictionary on their phone, not someone relying on it in airplane mode or with no signal.
Dealbreaker
Multiple recent reviews say offline mode stopped working after an update, or never worked at all, which is a serious problem for a dictionary app people buy specifically to use offline.
The facts.
Pulled from the App Store, not written by hand.

Where we recommend it
Dictionaries you buy once ›Offline dictionaries and thesauruses that charge a single price, with what each one misses.
Alternatives with the same rule.
Every app here is a single purchase. None of them can start charging you monthly for what you already bought. Also with a catch.

Verdict. Reviewers consistently praise its offline dictionary and thesaurus content and call it easy to use, with several explicitly contrasting the one-time fee against subscription-based rivals like Merriam-Webster.
Best for. Someone who wants a comprehensive dictionary and thesaurus they can look words up in without a data connection, and who's tired of subscription dictionary apps.
Dealbreaker. At least one reviewer notes the audible pronunciation feature doesn't work offline, so some functionality still needs a connection.
$9.99 once · 4.8★ (22,260) · Updated Sep 22, 2026
Verdict. A well-regarded dictionary app that reviewers say works offline after the one-time purchase, without ads or subscription upsells, though a handful of users report crashes.
Best for. Someone who wants a reliable, ad-free dictionary they can look words up in without a data connection, and who paid once instead of dealing with in-app subscription prompts.
Dealbreaker. A small number of reviewers report the app crashing on open or when saving words, so stability isn't universal.

Verdict. Reviews describe crashes on recent OS versions and a cramped, single-window layout that dumps all results into tiny print without font controls. That's a rough experience for an app whose whole job is readability.
Best for. Someone who already owns Roget's II in print and just wants occasional offline word lookups on an older iPad, and won't mind a dated interface.
Dealbreaker. Multiple reviewers report crashes on updated OS versions and a cluttered single-window display that's hard to read.
