Best Translator Apps for iPhone (2026)

Here is the short answer.

Most people: Google Translate. Up to 249 languages, the best camera mode, free. The catch is privacy — your translations run on Google's servers.

Just the basics, zero installs: Apple Translate. Already on your iPhone, free, fully on-device. About 20 languages and no camera mode.

Documents and email: DeepL. The most natural written translations here. Not built for spoken conversation.

Live spoken conversation: OmniTalk. Built for two-way voice, works offline and on-device, iPhone only.

The rest of this article explains why, with the App Store numbers to back it up. We compared the six translation apps iPhone users actually install — those four plus Microsoft Translator and iTranslate. Every number was pulled from the App Store listings or vendor documentation on August 11, 2026, and is linked so you can check it yourself.

How we compared

We compared published specs, prices, language counts, and privacy policies as of August 2026, and pulled the live App Store records (size, version, rating, release date) directly. We did not run a laboratory test, and we won't pretend we did. Where a claim comes from the vendor, we say so and link it.

One thing we did check properly: what each app documents about offline behavior. Every app in this category claims it, and it is the claim most likely to disappoint you at the airport.

The contenders at a glance

The numbers nobody puts on the marketing page

App size and rating history tell you more than any feature list. Live App Store data as of August 11, 2026:

Sizes are as the App Store reports them (MiB). Every row comes from the listings linked above.

What these numbers mean:

• Size tells you how the app is built. Google Translate needs 290 MB before you've downloaded a single language pack (packs download on top, some hundreds of MB more). iTranslate is 256 MB, DeepL 201 MB. Microsoft Translator is 26 MB, OmniTalk 18.9 MB, Apple Translate 5 MB. The small ones lean on Apple's built-in speech and translation models instead of shipping their own. If your phone is full and you fly often, that difference matters.
• Ratings reflect behavior, not just quality. Apple's own Translate app is the worst-rated thing in this category (2.34 stars) because it's a thin system utility: it works, and users expect more. iTranslate's 4.73 across 527,000 ratings is the category's largest evidence base.

Pick by pick

Google Translate: best coverage, cloud-based, data-hungry

Verdict: the default for most people, with a privacy caveat.

Google Translate lists up to 249 languages, more than everyone else here combined. Its camera mode is the best in the category — Lens integration reads signs and menus and handles printed text well. Conversation mode works, with the robotic latency you expect from cloud translation.

What you'll actually meet: translation happens in the cloud, so it needs a connection unless you pre-download packs. Packs download per language pair and Google refreshes them over Wi-Fi periodically; if they expire or were never downloaded, you get an error at the moment you need them most. Per Google's privacy policy, your translations are processed on Google servers and used to improve Google's services. Sensitive conversations (medical, legal, personal) go through that pipeline too.

Use it if: you want the most languages and the best camera, and don't mind the data. Skip it if: you want conversations to stay on your phone, or you don't want to manage per-language downloads.

Apple Translate: free, private, limited

Verdict: fine for basics. The category's most limited app, by design.

Apple's Translate is built into iOS, runs entirely on-device, and works offline once you download languages. For "how do I say this one thing" it's all you need, and nothing leaves your phone.

What you'll actually meet: no camera translation at all (Apple splits that off into Live Text in the camera app). The language list is roughly 20 and grows slowly; it launched with 11 in 2020. Conversation mode is basic: tap to talk, no advanced detection. Its 2.34-star rating tells you what users think of the feature depth.

Use it if: you translate a word now and then and want zero installs and zero data risk. Skip it if: you need camera translation, a language outside its list, or a serious two-way conversation tool.

DeepL: the best writer, not a talker

Verdict: the right app for documents and email. The wrong app for conversations.

DeepL's neural models produce the most natural written translations in this comparison, which is why businesses pay for it. The app (200.6 MB) adds camera translation, dictation, and file translation. The free tier exists but has limits, and DeepL has tightened them over the years; the Pro plan is where the product lives, including the offline mode, which is Pro-only.

What you'll actually meet: there is no real two-way conversation mode. You can dictate a sentence and hear it read back, but a live back-and-forth conversation is not what this app does. Per DeepL's policy, text is processed on its servers and deleted after translation, but it leaves your device to get there.

Use it if: you translate documents, email, or anything where the writing has to be good. Skip it if: your use case is spoken conversation.

Microsoft Translator: capable, free, slightly dated

Verdict: a reliable free option that feels like 2019.

Microsoft Translator does most things: text, voice, camera, conversation mode, offline packs and a web version. The app is small (25.6 MB) and highly rated (4.75 across 158,148 ratings). Its multi-device conversation feature, where each participant joined from their own phone, has been retired — the App Store listing now says so explicitly.

What you'll actually meet: Microsoft pushes you toward a Microsoft account for the full feature set, and your translations are processed by Microsoft's cloud. The interface is functional but unpolished compared with Google's. A workhorse with no wow factor.

Use it if: you want a small, free, capable all-rounder and don't care about polish. Skip it if: interface polish and data handling matter to you more than raw capability.

iTranslate: the most complete, behind a paywall

Verdict: a genuinely full-featured app whose best parts cost money.

iTranslate's own App Store description promises translation of text, websites, objects, and voice conversations in 100+ languages. It has a custom phrasebook feature, dialect voices, and the largest rating base in this category (4.73 across 527,000 ratings, accumulated since 2019).

What you'll actually meet: the free version is ad-supported and heavily limited. The subscription (about $5.99/month as of August 2026) pays for the features that make the app worth having, including offline mode. At 256 MB it's also the second-heaviest app here. Compare its paid tier directly against the free tiers of Google Translate and OmniTalk before you buy.

Use it if: you want one polished paid app for everything and the phrasebook appeals. Skip it if: you don't want ads, or you're comparing on price.

OmniTalk: built for conversations, iOS only

Verdict: the most specialized conversation tool here, with a hard platform limit.

OmniTalk is a real-time voice translator first; everything else is second. What the others do as a side feature, it does as the main event (how real-time voice translation works), and it has a few mechanics you won't find anywhere else in this comparison:

• Conversation view shows both languages. During a conversation you see the source language and the translation together, phrase by phrase, as they're spoken. Most apps show you only the translation; OmniTalk shows you what was actually said and what it means, side by side. Automatic speaker detection means nobody taps buttons between turns.
• Hands-free with earbuds. Put in AirPods or any earbuds and translations play in your ear while you keep talking — no phone in anyone's hand. Hand the other person one earbud and you each hear your own side. This one is PRO, not free. (Full breakdown: the best translation app for live conversation with AirPods.)
• Premium voices, not robotic TTS. Spoken translations are rendered in high-quality natural voices. This is the difference between "a computer read it" and "someone translated it for you."
• Conversation history stays on the device. Every conversation is saved on your phone so you can go back to an address, a price or a name — stored locally, never uploaded.
• Translate any video or audio on your phone. Play a video, a voice message, or a podcast and get a live translated transcript. The other apps translate files you import; OmniTalk translates what's playing on your phone.
• One-button quick access. Start a session instantly from Siri, Shortcuts, or the Lock Screen.
• Fast by design. Translations appear as you speak, not sentence-by-sentence with a loading spinner. The App Store listing says it plainly: "built for real conversations, not sentence-by-sentence waiting."
• Offline and private. The free BASIC mode uses Apple's on-device speech recognition and translation models. Download a language pair once, and recognition and translation run entirely on your phone, with no account (what on-device translation means). Live conversation on the free plan is capped at 1 hour a month; text and camera translation are not capped, and a PRO subscription removes the conversation cap. The 180° mode (one phone between two people, each reading their own language) and camera translation round it out.

How the plans split: OmniTalk is free to use. PRO (a subscription, priced inside the app) unlocks the most accurate real-time translation, hands-free earbud conversations, and video & audio translation.

Behavior you'll actually meet (documented in the support FAQ):

• A status badge shows whether a pair is running on-device or online. If it says "Online," the pair isn't downloaded yet, and translation goes through the cloud until you tap the badge to download it.
• Offline with an undownloaded pair: speech transcription still works, and the app tells you honestly that translation needs a one-time download.
• If your iPhone's ringer is on silent, spoken translations play silently. This surprises people.
• Camera translation needs camera permission and good lighting; stylized or handwritten fonts are harder to recognize, because recognition runs on-device.
• PRO mode requires an internet connection, and captive-portal Wi-Fi (hotel logins) can block it until you sign in.

Where OmniTalk loses: it is iOS only, so Android users are out. The camera mode has fewer features than Google's Lens integration. The language list (60+) is smaller than Google's and Microsoft's. And the features that make it special (PRO accuracy, hands-free earbuds, video & audio translation) sit behind a subscription, while the free tier is on-device BASIC.

Use it if: you want free, private, real two-way conversations, offline, on iPhone. Skip it if: you're on Android, or you only translate text.

Where these apps fail (and what the docs say)

Every app in this category fails in predictable places. Here is what the documentation actually says:

The pattern: cloud apps fail on connectivity, on-device apps fail on capability. Google fails you at the airport; Apple fails you on languages and camera; OmniTalk fails you on fonts, silence, and Android.

How "free" actually works

Every app in this comparison is free to install, and every one pays for it differently:

1. Google Translate is free because your translations are data. Processed on Google servers, used to improve Google's services.
2. Apple Translate is free because it's a platform feature. No data problem, and no ambition: about 20 languages, no camera, 2.34 stars.
3. DeepL's free tier shrinks over time. Plan for the subscription; offline is Pro-only anyway.
4. iTranslate's free version is an ad delivery system. The useful features sit behind a ~$6/month subscription.
5. OmniTalk's free tier gives 1 hour of live conversation a month, with uncapped text and camera translation, funded by the optional PRO subscription. That model only works while the free tier stays good enough to recommend.

Numbers change; every figure above is "as of August 2026."

Which one for you

• Most languages, don't care about data: Google Translate.
• Zero installs, zero data risk, basics only: Apple Translate.
• Documents and email, not conversations: DeepL.
• Free, private, real conversations, offline, on iPhone: OmniTalk.
• Android: Google Translate, Microsoft Translator, or DeepL; OmniTalk is not available to you.
• One app for everything, willing to pay: iTranslate or Google Translate, depending on whether privacy or polish matters more.
• Travelling and mostly reading menus: any of the free camera apps, plus a phrasebook for the ten sentences you'll actually say.

FAQ

Which translator app works offline?

Google Translate and Microsoft Translator (download packs per language), Apple Translate (download languages), and OmniTalk (on-device with downloaded pairs; free for text and camera, with live conversation capped at 1 hour a month unless you subscribe). DeepL offline requires the paid plan; iTranslate offline requires the subscription.

How much storage do translation apps need?

Google Translate is 290 MB before language packs (which add hundreds of MB more per language), iTranslate 256 MB, DeepL 201 MB, Microsoft Translator 26 MB, OmniTalk 18.9 MB, Apple Translate 5 MB. All figures from the App Store, August 2026.

Which translation app is most private?

Apple Translate and OmniTalk process translation on-device by default, with no account required. Google, DeepL, Microsoft, and iTranslate process your text or audio on their servers.

Why is Apple's Translate app rated so low?

It holds 2.34 stars on the App Store (9,769 ratings) because it's a minimal system utility: about 20 languages, no camera translation, basic conversation mode. It works; users want more.

Does OmniTalk work with any earbuds?

Yes — AirPods or any Bluetooth earbuds. Translations play in your ear while you keep talking, and you can hand the other person one earbud so you each hear your own side. Hands-free earbud conversation is a PRO feature, not part of the free tier.

How many languages does each app support?

Per App Store listings as of August 2026: Google Translate up to 249, Microsoft Translator 100+, iTranslate 100+, OmniTalk 60+, DeepL roughly 30, Apple Translate roughly 20.

Which app is best for live conversation translation?

OmniTalk is the only app in this comparison built specifically for two-way voice conversation: both languages on screen at once, automatic speaker detection, natural voices, hands-free earbud conversations, and one-button start from Siri, Shortcuts, or the Lock Screen. Google Translate and Apple Translate have conversation modes as secondary features.

Can I go back to what was said?

OmniTalk keeps a conversation history on the device — saved locally so you can revisit an address, a price or a name, and never uploaded. Most apps here keep some form of history; what differs is where it lives. For sensitive conversations, check each app's privacy policy before you rely on any of them.
