What This App Actually Offers

Oxford Dictionary & Thesaurus bundles 15 different Oxford dictionaries into one app, covering English, French, German, Spanish, Russian, Chinese, Italian, Hindi, Urdu, Portuguese, Japanese, Greek, Bulgarian, and Thai, plus a thesaurus and word-of-the-day feature. It’s aimed at students prepping for the SAT, IELTS, or TOEFL, professionals who use English regularly, and anyone who wants an authoritative reference rather than a random web definition. The core dictionary content is genuinely Oxford-sourced, which matters if you care about accuracy over convenience.

Where the App Genuinely Shines

Users consistently praise the pronunciation assistance, with one reviewer noting it has settled real arguments in their household over how words are actually said. The spell-checking and fuzzy search tools also get credit for helping people find words even when they’re not sure of the spelling, which is a real practical win for a mobile dictionary. The underlying content quality is not in question here; when you can actually get to the definitions, they’re solid and well sourced.

The Paywall Problem You Need to Know About

This is where the app loses a lot of goodwill. Multiple reviewers describe hitting a paywall just to read a basic word definition, and offline access is locked behind Premium too, which is a serious limitation if you don’t have reliable signal. One reviewer flagged that the free trial and subsequent renewal fee aren’t clearly disclosed upfront, only surfacing after you’ve already installed and agreed to terms. Given the store listing calls this a straightforward reference tool, the aggressiveness of the monetization catches people off guard.

Ads and Interface Annoyances

Even after looking past the paywall, reviewers report ads appearing nearly every time they search for a word, which several called obnoxious for something marketed as a quick-reference tool. One user said an ad filled the screen before they’d even chosen which dictionary to search. There are also structural gripes: entries for words with multiple meanings (like ‘affect’ having three separate listings) require repeated clicking and backing out instead of showing all senses on one page, which slows down what should be a fast lookup.

Value for Paying Users

Even people who paid for the app aren’t fully satisfied. One reviewer who bought it a few years ago for around $5 expected that to cover ad-free offline use going forward, only to find that expectation didn’t hold up over time. Others note the $20-a-year Premium price isn’t unreasonable in isolation, but feels like a lot to ask for what should be a basic lookup function, especially with lag reported when scrolling through entry pages.

Who Should Actually Download This

If you want serious, Oxford-backed definitions across multiple languages and are willing to pay for Premium from day one, this app can genuinely deliver, especially for pronunciation and spelling help. But if you’re expecting a free, lightweight dictionary for occasional lookups, the ad load and paywalled definitions will likely frustrate you fast. Students and professionals who rely on a dictionary daily should budget for Premium; casual users may be better served by a free alternative.

What Real Users Say

Laura Crafton ★ 5/5

“It's, quite obviously, useful in a great number of different ways. Spell checking and definitions clearly being the top of the list. The pronunciation assistance has been the most primarily useful one, though, for my family. We have (myself not included - I just watch and listen) arguments and disagreements over such that have, in the past, lasted for months!…”

“Worst dictionary app I have ever use. To be able to read the definition of a word you're looking for, I need to either watch an ad or buy for "Premium". Yes, there's a paywall to use a dictionary. Offline access is also behind a paywall too, so if you don't have a good signal, good luck. Plus, there's an…”

S SMART ★ 1/5

“This is NOT a free dictionary as it is described! Even the fine print in the agreements (yes I read all of them) doesn't mention that it's not a for free service. It's not until you've installed it read the agreements and then hit start that you find out there's a three-day trial and thena renewal fee of $19. 99…”

Frequently Asked Questions

1

What is Oxford Dictionary & Thesaurus?

It's a reference app from MobiSystems that bundles 15 Oxford dictionaries, including English, French, Spanish, German, and Chinese, along with a thesaurus and word-of-the-day feature. It's designed for students, professionals, and academics who need authoritative language references on their phone. The app also includes tools like voice search, camera search, and wildcard search to help you find words quickly.

2

Is Oxford Dictionary & Thesaurus free to use?

It's free to download, but multiple users report that even basic definitions are gated behind ads or a Premium subscription. Offline access and unlimited synonym lookups also require paying for Premium. Several reviewers were frustrated that the free trial and renewal terms weren't made clear before installing.

3

Does the app work offline?

Offline access is listed as a Premium-only feature, according to both the app description and user reviews. If you don't have reliable internet, you'll need to pay for the subscription to use the dictionary reliably. Free users without signal have reported being unable to access definitions.

4

How many ads does the free version have?

Users report seeing ads very frequently, with some describing an ad appearing almost every time they search for a word. One reviewer said a full-screen ad appeared before they had even chosen a dictionary. This is one of the most common complaints in user reviews.

5

Is Premium worth paying for?

If you need reliable offline access, ad-free browsing, and audio pronunciation, Premium does unlock real value, especially given the strength of the underlying Oxford content. However, some paying users still report lag when scrolling and awkward navigation for words with multiple meanings. It's worth it for frequent users, but casual users may not find it necessary.
