Bonjour RATP vs Île-de-France Mobilités: Which App Should Tourists Use in 2026?

Quick Answer

Key facts

What both apps do

There are two official apps, and they overlap a lot. Both Bonjour RATP and Île-de-France Mobilités (IDFM) let you:

• plan journeys across the metro, RER, bus, tram, Transilien trains and bikes;
• buy and store tickets on your phone or load them onto a Navigo card;
• see real-time traffic and disruption alerts;
• pay with a bank card, Apple Pay (iPhone) or Samsung Pay (Android).

So you rarely need both. The differences are about polish and focus. For how buying and validating actually works, see buy tickets on your phone.

Bonjour RATP — smoothest for getting around

Bonjour RATP is made by RATP Smart Systems and is known for a clean, intuitive interface and strong real-time information. Its standout feature in 2026 is the "Recommended Itinerary": when the app expects a normal alternative route to be crowded — likely during this year's intense engineering works — it suggests a smoother route and lets you plan up to 30 days ahead to see how works affect your trip.

It also lets you name and style each digital Navigo card, which helps if you carry several. One thing to note: its app-store listing flags data used for tracking, so privacy-minded travellers may prefer the authority app.

Best for: travellers who want the nicest planner and the smartest routing around disruptions.

Île-de-France Mobilités — the authority's all-in-one

IDFM is the app of the regional transport authority — the body that actually sets fares and runs the network across all operators. Many experienced users find it well organised and complete: it plans journeys, sells the full range of tickets and passes, and turns your phone into a Navigo card. On iPhone, single tickets and day passes need no account.

Best for: travellers who want one official app that does everything, especially if buying weekly or monthly passes.

The third option: Apple Wallet (iPhone only)

If you have a recent iPhone and only need a few single tickets or a day pass, you can skip both apps. Open Apple Wallet, add an Île-de-France Mobilités transit card, buy with Apple Pay and tap to ride. Weekly and monthly passes still need one of the apps. Many visitors also plan routes in Citymapper or Google Maps and use an official app only to buy tickets — those map apps cannot sell tickets.

Side-by-side comparison

Which should you install?

• Short visit, iPhone, a few rides: use Apple Wallet. Add Bonjour RATP only if you want a nicer planner.
• You want the best routing during 2026 works: Bonjour RATP.
• You are buying a weekly or monthly pass, or want the official all-in-one: Île-de-France Mobilités.
• Android user: pick either app — the Apple Wallet shortcut is iPhone-only, so you need an app to buy and store tickets.
• Privacy-conscious: lean toward Île-de-France Mobilités, the authority app.

Real examples

• Solo visitor, 3 days, iPhone: Apple Wallet for tickets, Bonjour RATP for planning around works.
• Couple, one week, buying weekly passes: Île-de-France Mobilités on each phone.
• Android traveller: install Bonjour RATP or IDFM — one app covers planning, buying and validating.
• Family: each adult needs the app or Wallet on their own phone; you cannot share one phone's tickets.

Common mistakes

• Installing both and getting confused. Pick one app for tickets and stick with it.
• Expecting Google Maps or Citymapper to sell tickets. They only plan routes.
• Ignoring live alerts during summer 2026 works. Check the app before you travel.
• Assuming Apple Wallet covers weekly passes. It does not — use an app for those.
• Buying on Android and expecting it in Apple Wallet. Wallet is iPhone-only.

Conclusion

For most tourists, the simplest setup in 2026 is: on iPhone, buy single tickets in Apple Wallet and add Bonjour RATP for its cleaner planner and disruption routing; on Android, install Île-de-France Mobilités or Bonjour RATP and let it do everything. If you are buying weekly or monthly passes, favour Île-de-France Mobilités. You do not need both apps — choose one for tickets and travel light.
