YASNO is a free mobile app developed by KEP for Android users in the Business & Productivity category, specifically for finance. With YASNO, users can conveniently manage their utility bills on-the-go.

The app's mobile version displays personal account information for electricity and gas, just like in the YASNO personal account. With the updated YASNO mobile app, users can easily and quickly submit their electricity meter readings, turn on the flashlight with one click if the meter is in a dark place, pay electricity and gas bills without commission, calculate payments for all utilities, internet, television and mobile communication, save paid bills and send them via any messenger or email, create, save, and edit payment templates, track payment history, and order and pay for energy-efficient products in the YASNO online store. YASNO operates on the "single window" principle, making it a convenient and fast app for managing utility bills.
