Collins's Greek pairing on DioDict 3 is the rare Galaxy dictionary with a real publisher behind it.

DioDict 3 is Diotek's long-running dictionary shell, and this Galaxy Store edition ships with the licensed Collins English-Greek and Greek-English wordlist as its payload. Type an English word and you get the Collins entry with its Greek translations, part of speech, and sense divisions. Reverse the direction and Greek headwords resolve to English with the same structure. Everything lives on-device, so the dictionary opens on a plane the same as it does on Wi-Fi.

The reading screen is the dictionary-app standard: a headword bar at the top, a scrollable entry below, a small toolbar for history and bookmarks. Tap any Greek or English word inside an entry and DioDict jumps to its own entry — a hyperlinked cross-reference that turns sense-reading into actual browsing. There is a clipboard hand-off, a small font-size control, and a history list that survives restarts.

The app is free on the Galaxy Store and runs only on Samsung hardware via the DioDict 3 platform. There are no subscriptions, no ads, and no second-tier dictionary upsell — Diotek's Galaxy Store catalogue is a flat list of single-pair editions, and this is the Greek one.

The lexicon is the headline and it earns the billing. Collins's bilingual dictionaries are edited by lexicographers, not crowdsourced from a wiki, and the Greek pairing carries the same definitional discipline as the rest of the Collins shelf. Headwords have sense numbering, register tags, and short example collocations where the entry warrants them. For a free Galaxy app, that is a much better source than the genre median.

The lookup is fast and quiet. Type a few letters, the autocomplete narrows the list, tap, the entry is there. No splash screen, no rewarded video, no nag for an account. It is the kind of utility you can build into a habit because it never asks for anything in return.

DioDict 3's interface is visibly the same one Diotek shipped a decade ago. Typography is thin, the layout assumes a smaller screen than current Galaxy phones provide, and the chrome looks dated next to a 2025-era Android dictionary like Reverso or Cambridge's own app. There is no dark mode worth speaking of, no widget, no Quick Search Tile.

The Greek polytonic question is where the age hurts most. Modern Greek learners can mostly ignore polytonic accents, but anyone reading classical or Katharevousa text wants the diacritic distinctions to be searchable both ways, and DioDict 3's input handling here is unfussy at best. Audio pronunciation is absent. There is also no inflection table — useful in a language where nominal morphology does real work — which a competing learner-grade dictionary would include.

Install it if you want a credible offline Collins Greek dictionary on a Galaxy phone and you can live with a Samsung-era app shell. Travellers, intermediate learners, and anyone tired of pasting words into a browser tab will get their money's worth, and the price is zero. Serious classicists and learners chasing audio or grammar tables should pair it with a desktop lexicon or a paid Greek-specific app.
