RRReis is a free Android app developed by Keolis Nederland BV that allows you to plan, book, and pay for your travel in one place. The app is perfect for those who want to choose how they travel and aren't tied to one mode of transportation. RRReis is the brand for public transportation in large parts of Gelderland and Overijssel, and it keeps adding new types of transportation such as shared bikes and soon shared scooters. You can also use your own bike or car for all or part of your journey.

The app's unique journey planner allows you to combine all modes of transportation in one trip and discover the fastest, cheapest, or most sustainable way to reach your destination. If you prefer not to make transfers, you can choose a single mode of transportation. Save your trips in favorites and travel quickly and easily to home, school, or work. The RRReis app provides solutions, but you are in control.
