Простор is a free Android app developed by ООО АРПС that allows you to remotely top-up your transport card. The app is designed for transport cards accepted as payment for public transport in the Rostov region. You can check your card balance, replenish it remotely, track its status and view your top-up history with ease.

To get started, simply install the app and register using your phone number. You can then top up any Простор transport card with any amount between 50 and 1500 rubles, with a commission of 6%. The maximum balance allowed on the card is 15,000 rubles.

On the main screen, you can view the category and status of your card - whether it is active or blocked. In the "History" section, you can view the top-up history of your card. To use the app, you need an Android smartphone with NFC functionality and version 6.0 or higher.
