The McLaut АЗК application is designed for individual clients looking to manage their fuel purchases effectively. It allows users to authenticate using their phone number and a one-time code, ensuring secure access through PIN or fingerprint protection. Upon first login, users are introduced to the app's main features, including notifications and a history view. A dynamic QR code facilitates identification during payments, granting immediate discounts based on loyalty levels, which are tracked within the app.

The app provides a map view of fuel stations, with details on addresses, operating hours, fuel prices, and available services. Users can search for the nearest fuel station and plan routes accordingly. Customization options include light/dark themes and a left-handed mode. Data encryption ensures user privacy, while feedback can be sent via text or voice. Discounts are exclusive to app users, with a loyalty program that rewards increased fuel purchases with higher discount levels, categorized into three tiers.
