REVIEW
DeepL still translates European prose better than anyone else.
The Cologne-built translator that professional linguists actually trust now ships a Voice mode and a Write tab, but its language list remains shorter than the competition's.

DeepL launched in 2017 as a research bet — a Cologne-based team claiming a neural translation network that beat Google’s for European-language quality. The benchmarks held up, the linguists agreed, and a decade later DeepL is still the translator that professional translators reach for when the brief is German legal text or a French press release.
The iPhone app exists in the long shadow of that reputation. It is not trying to be the universal translator on your screen — Google Translate already owns that lane and a hundred languages of it. DeepL is trying to be the one you open when the translation actually has to read well.
Where Google reads literally and asks you to fix the tone, DeepL reads for register and asks you to fix the meaning. That is a different kind of tool, and for the right kind of work it is the only one worth installing.

FEATURES
The iPhone app does the obvious things — type, paste, photograph, or speak a phrase and get a translation back in any of the supported languages. The supported list sits around 35, which sounds slim next to Google Translate's 130-plus until you notice that the 35 are the ones DeepL has actually tuned for register, idiom, and grammatical agreement.
DeepL Voice — added in late 2024 and rolled to iOS in 2025 — is the more interesting recent addition. It transcribes a live conversation in one language and surfaces a running translation in another, with both transcripts visible side-by-side on screen. The Write tab handles the other direction: paste a paragraph of your own writing and DeepL will rephrase it for tone, formality, or concision in the same language.
Glossary entries (Pro only) pin specific term translations so company names, product SKUs, or in-house jargon survive the round-trip. Document translation accepts Word, PowerPoint, and PDF files and preserves layout reasonably well. iCloud keeps the history in sync across iPhone, iPad, and Mac.
MISSION ACCOMPLISHED
The translation quality is the entire pitch and it still holds. German into English reads like English. French into English keeps the register of the source — formal stays formal, casual stays casual, the subjunctive doesn't get flattened into something a tourist would say. The same is true in reverse for the European languages DeepL has spent a decade tuning: Polish, Dutch, Italian, Portuguese, the Nordics.
Pricing is honest. The free tier covers casual use without ads. DeepL Pro starts around $10.49 a month for individuals, lifts the character cap, unlocks glossaries, and turns on the formality dial. Files translate without watermarks, and Pro accounts get the no-data-retention guarantee that DeepL's enterprise customers buy the service for.
ROOM TO IMPROVE
The language list is the visible ceiling. If you need Hindi, Vietnamese, Thai, Swahili, or any of the dozens of African and Southeast Asian languages Google covers, DeepL cannot help you yet. Asian language quality has improved — Japanese and Chinese are credible now — but they still trail the European tier by a noticeable margin.
The iOS app itself is the weaker DeepL surface. The camera-translate flow lags behind Google Lens for live overlay translation of signs and menus, and the Voice mode works best when both speakers can see the phone screen, which is a strange constraint for a conversational tool. Offline translation is not available — every request needs a connection — and that is a real gap when you are underground in Berlin or in a tunnel under the Alps.
CONCLUSION
If your translation work lives inside the European languages DeepL was built around, this is the only translator worth paying for. Travellers who need broader language coverage or live camera translation should keep Google Translate on the home screen too — the two apps complement each other more than they compete. Watch for the offline mode DeepL keeps hinting at; that is the feature that would close the last real gap.
