WhatsApp vs Apple vs Aeva: message translation for couples, compared honestly

The big messengers have added translate buttons, and most of them are free. For a lot of couples that's enough. Here's what each one actually does — and when it isn't enough.

We make Aeva, so take our view with that in mind. We've tried to stick to what each company has published, link to the source, and be clear where the free options are the better choice. Features change quickly; everything below is as of October 2026.

The short version

• If you share some language and only need help with the odd message, the translate button in the app you already use is free and probably enough.
• If every message needs translating, you want to send voice messages, or your language pair isn't covered, a translate button turns into a chore — that's the case Aeva is built for.

What each option does

Where the built-in options are the better choice

Being straightforward about this: if one of these describes you, you probably don't need Aeva.

• You mostly talk in a shared language and only occasionally want a word or sentence decoded.
• You don't want another app. Built-in translation lives where your chats already are, and it costs nothing.
• On-device translation matters to you. WhatsApp says its translations stay on your device; Aeva's translation runs in the cloud.
• Your languages are covered on both of your phones — say, English and Spanish on recent iPhones.

Where a translate button starts to get in the way

Translate buttons are designed for the occasional foreign message in an otherwise single-language chat. A relationship where you don't share a language is a different situation: every message is foreign to one of you.

• The tap adds up. Long-press, translate, read; then write in a language that isn't yours, or paste from somewhere else. Over hundreds of messages a week, it's a lot of friction in the most important chat on your phone.
• Writing is the hard half. Most translate buttons help you read. They don't help you write naturally in your own language and have it arrive in theirs.
• Tone and jokes. Teasing, irony and affection are what get lost first in a literal translation, and they're most of what a couple says to each other.
• Voice messages. Hearing each other matters. A text translate button doesn't help with a voice note.
• Language coverage. As of October 2026, Ukrainian and Russian aren't covered by Apple's Live Translation, and Ukrainian wasn't in WhatsApp's Android launch list.

That's where Aeva fits. The idea is "be yourself in your own language": you both write without thinking about translation, with your own humour, and Aeva carries over the tone rather than a word-for-word version. Voice messages come out spoken in the other person's language.

So which should you use?

Nothing stops you from using both: keep your usual messenger for everything else, and use Aeva for the conversation where language gets in the way.
