Mappy remains one of the few French route planners to natively offer multimodal comparison for the same journey: car, public transport, bike, pedestrian, carpooling, train. The calculation engine incorporates real-time traffic and adjusts the suggestions according to the selected mode of transport. Here’s how to leverage its less visible functions to obtain a reliable route without spending a dime.
Transfer from website to mobile app via QR code on Mappy
Most users prepare their journey on a computer and then switch to their phone when it’s time to leave. Mappy now offers a route transfer via QR code: the route built on the website is displayed as a scannable code, retrievable directly in the mobile app.
This continuity avoids double entry of the departure and arrival addresses and retains the intermediate steps added manually. We recommend finalizing the complete route (waypoints, mode of transport, toll preference or not) before generating the QR code, as any subsequent changes on the website do not automatically sync to the mobile.
To calculate a route with Mappy from the browser and then transfer it, simply click on the share icon that appears next to the route summary. The QR code is displayed overlaying the map.
Walking and biking route calculation: the non-recalculation parameter
In car mode, automatic recalculation when deviating from the route is expected. However, for walking and cycling navigation, this behavior is problematic: a hiker following a pre-prepared route does not want the app to redirect them to another path at every detour.
Mappy has added a specific option: do not recalculate the route when deviating from the planned path. Specifically, the app continues to display the original route and the user’s GPS position without suggesting a new route. This is a useful function for field uses where one wants to stay true to a planned course.
To activate it, you need to access the navigation settings before starting the guidance. The option only appears when the walking or biking mode is selected.
Voice guidance and free AI route on the Mappy app
The iOS app of Mappy integrates voice guidance and displayable directions on Apple Watch. The August 2026 update introduced an additional layer: three free AI routes per month. This mode generates an optimized route based on cross-criteria (expected traffic, estimated consumption, road preferences) that the classic calculation does not combine.
Beyond three monthly uses, access to the AI route is through the Mappy Plus offer. In practice, the three free calculations are sufficient for occasional trips, typically a vacation departure or a business trip to an unknown destination.
Comparison between classic route and AI route
| Criterion | Classic route | AI route |
|---|---|---|
| Real-time traffic | Yes | Yes, with forecast |
| Consumption optimization | No | Yes |
| Free monthly limit | Unlimited | 3 per month |
| Availability | Website and app | App only |
The classic calculation remains relevant for short and urban trips. The AI route is particularly beneficial for long journeys where variations in traffic and consumption impact the budget.
Transport modes compared in Mappy: car, train, carpooling
Mappy displays results side by side for several modes of transport on the same journey. The comparison focuses on duration, estimated cost, and carbon footprint. We observe that this feature remains underutilized even though it allows for quick arbitration between car and train on routes such as Paris-Lyon or Paris-Marseille.
The available modes cover a wide spectrum:
- Car and motorcycle, with options for the fastest, shortest, or toll-free route
- Public transport, including metro, bus, tram, and RER in Île-de-France
- Biking and scooter, taking into account the referenced bike paths
- Carpooling, long-distance car, and train, with redirection to operators
- Walking, with estimates of walking time and elevation
The cost of the car trip is customizable: Mappy allows users to input the actual fuel consumption of the vehicle and the price of fuel. This setting refines the comparison with the price of a train ticket displayed alongside.
Traffic alerts and control zones on the Mappy GPS
The GPS integrated into the app alerts users to control zones on the current route. The alert signals the beginning and end of the zone, reminds the maximum speed limit, and warns in case of exceeding it. Temporary construction speed cameras are also taken into account.
For daily trips, Mappy offers custom alerts on traffic conditions. By saving a home-work route, the user receives a notification before their usual departure if an incident disrupts the journey. The real-time recalculation then proposes an alternative route.
These traffic functions rely on data reported by active users of the app and on national road information flows. The reliability directly depends on the volume of users on a given route: on major routes, coverage is dense, while on less frequented departmental roads, reports may be delayed.
All of these features, from QR code transfer to AI guidance and non-recalculation for pedestrians, remain accessible without a subscription for regular use. The only limit concerns the AI route beyond three monthly calculations. For a free route planner, Mappy covers a technical scope that few French competitors offer on a single platform.
