Advertising is our main source of income. We depend on it because we need to pay for our servers or the right to use the program data and images from the TV stations. These royalty fees are due every time a user starts the app, so unfortunately we cannot offer ON AIR for a one-off purchase price. And not to forget: We are a small team who earns a living from the app.
For those of you who would like to use ON AIR without advertising, we have developed an ad-free-version that you can purchase for 2 months or one year. To do so, please open your settings and click "ON AIR without ads".
