Traveling without speaking the language: what actually works

What actually works on a trip is a short face-to-face conversation: you set your phone between you and the other person, each of you speaks your own language, and the translation appears on screen and is read aloud. Download the languages before you leave and it works without a signal, from a noodle shop to a pharmacy counter. The rest takes a little prep: your rental’s address written in the local language, a host willing to message on Piou, and a human for anything medical.

The night before you fly

On home Wi-Fi:

1. In Settings → Language & translation, make sure your language is set.
2. Download your language and the one spoken where you’re going. It’s a one-time download, and it’s what makes translation and Face to face mode work offline.
3. Turn on airplane mode and open Face to face. If the translation shows up, you’re set.
4. Check speech recognition, which depends on what your phone supports for each language.
5. If you start the 7-day free trial, put the end date in your own calendar: unless you cancel before then, the subscription starts automatically at the price shown.

Face to face mode is part of Piou Premium. Messaging is free.

Ordering food

Put the phone on the table, open Face to face and keep sentences short. It detects who’s talking, shows the translation and reads it aloud, so the server doesn’t need the app.

• “Does this dish have peanuts in it?”
• “I don’t eat pork. What would you recommend?”
• “Could we get the check, please?”

Two limits. Piou doesn’t translate photos, so snapping the menu won’t help; ask the server to describe two or three dishes, or point to the line you’re curious about. And a serious allergy shouldn’t rest on machine translation alone: before the trip, have someone who speaks the local language write your allergy on a card you can show, and keep it in your wallet.

At the pharmacy

For a sore throat or a bug bite, Face to face mode lets you describe symptoms simply: since when, where, how bad. Then ask the pharmacist to repeat the dosage and write it in numbers on the box, like “1 tablet, 3 times a day.” If you take a regular medication, bring its original box: showing the name printed on it is often clearer than saying it. If anything is unclear or the symptoms are serious, see a doctor and ask for an interpreter. In an emergency, call the local emergency number from your phone’s regular dialer; Piou can’t call regular phone numbers.

Taxis and getting around

• The address. Ask your hotel or host to send the address in the local language in a message. Tap “Show original” and hold it up for the driver.
• The fare. Confirm a price, or check that the meter is on, before you set off, using a calculator if needed.
• Directions. “Please stop here.” “Can you wait five minutes?” Short sentences, one at a time.

Proper names, like streets, neighborhoods and landmarks, are a known weak spot of machine translation and can get translated word for word. An address written by a local is still your safest bet.

Your host, and people you meet

If your rental host agrees to install Piou, you can sort out check-in before you even leave: arrival time, door code, parking. For the door code, turn on Disappearing messages in that chat (24 hours, 7 days or 90 days). On arrival day, share your live location for a set time so your host can guide you to the door, and call them on Piou if needed; the call goes over the internet, between Piou users.

Keep in mind that translation is personal. With Premium, you read your host in your language; for your host to read you in theirs, they need Premium too, or they’ll see your messages in English.

Hit it off with a guide, or with a family who had you over for dinner? Show your invite QR code. Once they’re on Piou, you can keep writing after the trip, each in your own language, and share photos in the chat. Photos aren’t translated, but they rarely need to be.

What Piou won’t do on a trip

• It doesn’t translate menus, signs, photos or documents.
• It doesn’t call regular phone numbers, so you can’t book a table by phone with it.
• Without a connection, you can’t send or receive messages or make calls; offline, only translating messages you’ve already received and Face to face mode work.
• It covers 20 languages, no more: Khmer, Lao, Burmese and Greek, for example, aren’t among them. Dialects aren’t guaranteed.
• Humor, sarcasm and idioms often come out wrong.

Manners still matter

Learn hello, thank you and please in the local language and say them yourself; they open more doors than any translation. Show the screen, smile, and give people a moment to understand what’s going on: not everyone is used to talking to a phone. If someone looks unsure, start with a simple “Hello” in Face to face mode, so they hear how it works before the real question.

Premium starts with a 7-day free trial: a card is required, nothing is charged for 7 days, and the subscription then starts automatically at the price shown unless you cancel before the trial ends. In the US, it’s $5.99 a month or $47.99 a year; in the UK, £4.99 a month or £39.99 a year. The exact price for your country is shown before you subscribe, in local currency. Piou runs on iPhone (iOS 18 or later), Android (8.0 or later) and as a web app.
