9 Apps for Your Au-Pair Year (Language, Money, Transport & Contact)

The most useful apps for an au-pair year cover four basic needs: learning the language, sending and managing money abroad, getting around locally, and staying in touch with family back home. If you have one app for each of these four areas on your phone, you're well set up for the first few weeks — the rest you'll discover along the way.
In this guide we look at nine well-known examples, grouped by purpose. One thing up front: these are popular examples, not paid endorsements. Which app actually works best in your destination country (especially for transport and payments) is something you're best off checking once you're there.
The 9 apps at a glance
| App | Category | What it's for |
|---|---|---|
| Duolingo | Language | Daily vocabulary and grammar practice, free to start |
| Babbel (or Pleco for Asian languages) | Language | Structured courses or a dictionary for the local language |
| Google Translate | Translation | Live text, voice and camera translation — handy for everyday life |
| DeepL | Translation | More natural translations for longer texts and messages |
| Wise | Money | Low-cost international transfers and a multi-currency account |
| Revolut | Money | Card and app for paying and withdrawing abroad |
| Google Maps | Transport | Walking, driving and often public-transport routes |
| Local transit app / Citymapper | Transport | Real-time schedules and tickets for your city on the ground |
| WhatsApp / FaceTime | Contact | Messages and video calls home and with the host family |
Learning the language
The language is at the heart of the au-pair year. A learning app like Duolingo or Babbel won't replace a proper language course, but it keeps you practising between lessons — ideal for ten minutes on the train. Which app fits depends on the language: many European languages have plenty of options, while for Asian languages a specialised app (such as a dictionary like Pleco for Chinese) is often more useful.
Alongside that, put a translation app on your phone. Google Translate can translate text, speech and even signs live via the camera — handy when shopping or at the doctor's. DeepL often gives more natural results for longer texts. Don't rely on either blindly, but for everyday life both bridge the first weeks well.
Sending and managing money
Living abroad, you'll want a simple way to move money between countries — to send some of your pocket money home, or top up from home. Apps like Wise or Revolut are popular for this because they usually make international transfers cheaper than traditional banks and offer an account in several currencies. They also come with a card for paying and withdrawing cash locally.
Check beforehand whether the app is available both in your home country and in your destination, and which ID documents you'll need to sign up. In some countries a local bank account is worth having too — discuss this early with your host family.
Getting around
For the way to your language course, the playground, or your free weekend, you'll need a navigation and public-transport app. Google Maps is a good starting point almost everywhere and shows bus and train connections in many cities. For accurate real-time schedules and tickets, though, the local transit app is often the better choice — in Germany, for example, the app of your regional transport network. In bigger cities, Citymapper bundles many modes of transport together. Download it in your first days and ask your host family which one is standard locally.
Staying in touch
Homesickness is part of the au-pair year — and regular contact with home helps enormously. A messaging and video app like WhatsApp or FaceTime is a must: for video calls with family and friends, and for quick coordination with your host family. It also helps to keep a shared family calendar (such as Google Calendar) where childcare hours, the children's appointments and your days off are visible to everyone. That prevents misunderstandings and makes planning easier for both sides.
Don't forget digital safety
Apps for money, messages and personal data come with responsibility. A few simple habits keep you safe:
- Strong, unique passwords for every app — ideally managed with a password manager.
- Two-factor authentication (2FA) enabled wherever possible — especially for money and email apps.
- Regular backups of your photos and important data, in case your phone is lost or stolen.
- Don't share anything sensitive too early. Only pass on ID copies, bank details or your exact address once a contact is genuinely trustworthy and verified — not in the very first message.
Tip: Set up all your key apps before you leave and test them once — create the account, check the login, enable 2FA. Doing this on the ground with a foreign SIM card or without stable Wi-Fi is far more awkward than doing it calmly at home.
