Luxembourg
Useful apps for Luxembourg: transport, maps, translation
Install Mobiliteit.lu and CFL before you land: they cover every free bus and train in Luxembourg, and Google Maps is fine for walking and driving. Add a taxi app only if you need late-night door-to-door, since buses and trains cost nothing and run until roughly midnight. Check your own bank and roaming app before departure.

Details
Set up two apps before you arrive and the rest is optional. Mobiliteit.lu is the national journey planner: enter a start and end point and it returns bus, train and tram options with times and platform numbers. CFL is the national rail operator's own app, useful for cross-border trains to Trier, Metz, Brussels and Paris, and for live delays. Both are free and in English.
Google Maps handles walking and driving well, including the Ardennes roads and the Moselle wine villages. Download an offline map of the Müllerthal and the Ardennes before you go: mobile coverage thins out in the wooded valleys, and the trail network is easier to follow with a map than with signs alone. Organic Maps and other OpenStreetMap-based apps are a good offline backup for hiking.
For taxis, Luxembourg has no single dominant ride-hailing app. Local taxi firms take bookings by phone or their own app, and availability of international platforms is limited — check what is live when you arrive. You will rarely need one: buses and trains are free nationwide, and the last services run until roughly midnight, later on Fridays and Saturdays. A taxi is mainly for very late nights, early flights or luggage-heavy station transfers.
Language is rarely a barrier. French, German and Luxembourgish are the everyday languages, English is widely spoken in the capital and in tourism, and staff in hotels, restaurants and stations switch to English easily. A translation app is still handy for pharmacy labels, rural bakeries and small shops outside the capital. For connectivity, an EU/EEA SIM roams at home prices; a Luxembourg prepaid SIM from POST, Tango or Orange Luxembourg needs photo ID. Free HotCity Wi-Fi covers public spaces in the capital.
Payments are mostly contactless card, including on the rare paid service such as first-class rail upgrades. Keep a small amount of cash for markets and small village businesses. GouvAlert is the government emergency alert app; it is worth installing if you are driving in winter or hiking in the Ardennes.

Tips
Screenshots beat signal. Save your bus and train times, hotel address and ticket confirmations as images before a day trip; coverage in the Ardennes and Müllerthal valleys is patchy.
Near the borders your phone may jump to a French, Belgian or German network. That is normal and, with an EU/EEA SIM, costs the same as at home. If you are on a non-EU SIM, switch off data roaming before you cross.
The free transport means you do not need a ticketing app for buses and trains. Do not buy a ticket you do not need; check the current rules for first class and cross-border services before you travel.
If you rely on your phone for maps, carry a power bank. Long hiking days and cold weather drain batteries faster than city days.
