Quick answer
There is no single best translation app—the right one depends on the job:
- Text, signs, documents → Google Translate, DeepL
- Live phone calls → AI Call (purpose-built, both sides, 100+ languages)
- Real-time voice → AI Call
- Live video calls → AI Call (two-way voice + subtitles)
- Quick in-person speech → Apple Translate, Google Translate
If your real need is talking to a person on the phone across languages, a phone call translator is the category that matters—most general apps stop at text.
Comparison: best translation apps (2026)
| App | Text | Voice | Live phone calls | Video calls | Languages |
|---|---|---|---|---|---|
| AI Call | Limited | Yes | Yes | Yes | 100+ |
| Google Translate | Yes | In person | No | No | 130+ |
| DeepL | Yes | Limited | No | No | 30+ |
| ChatGPT Voice | Yes | On device | No | No | Many |
| Apple Translate | Yes | In person | No | No | ~20 |
The pattern is clear: the big general apps win on text and offline phrasebook use, while live calls are a separate problem only a dedicated tool solves.
Best for text and documents: Google Translate & DeepL
For written translation, Google Translate has the broadest language coverage and a great camera/photo mode for signs and menus. DeepL produces more natural, nuanced text in the languages it supports and is a favorite for European business writing. Neither is a phone call translator, but they are excellent for messages, signs, and documents.
> Note: AI Call does not do certified document translation. For contracts, legal filings, or official paperwork, use a dedicated document/translation service or a certified human translator.
Best for live phone calls: AI Call
AI Call is the only option in this list built specifically for live phone calls to real numbers:
- translates both sides in under 0.5 seconds
- works on mobile, landline, and VoIP numbers
- the other person needs no app
- 100+ languages, with transcripts
This is the core real-time voice translator use case for calls—calling a hotel, a clinic, a supplier, or a family member who speaks another language. See the phone call translator page for details.
Best for in-person speech: Apple Translate & Google Translate
Standing next to someone? Apple Translate (on iPhone) and Google Translate conversation mode handle quick face-to-face exchanges on one device. They are convenient and free, though they are not designed for calls.
Best for AI chat + casual voice: ChatGPT Voice
ChatGPT Voice can translate on your own device and answer language questions conversationally. It is great for practice and one-sided help, but it does not place or translate a live phone call between two people. See can ChatGPT translate phone calls for the honest limits.
