GUIDO is a free Android app developed by Carsharing Russia, aimed at providing a car-sharing service to users in the region. The app is designed to allow users to easily find and rent a car for their personal use.

The app is well-designed with a user-friendly interface that makes it easy to navigate. Users can search for available cars in their area and filter results based on their preferences. The app also provides information about the car, including its make and model, fuel type, and availability.

Another great feature of GUIDO is the ability to reserve a car in advance. This is especially useful for users who need a car at a specific time and don't want to risk not finding one available. Overall, GUIDO is a great car-sharing app that provides a convenient and affordable alternative to traditional car rental services.
