Webcomics is the app right?
If you download the tapastic app you can choose different ways of getting 'ink' besides money, each episode cost around '375 ink' but if you click the 'one tap' option that appears on the bottom of the screen it goes down to '300 ink' and you can get ink by watching ads, each ad gives you 10 ink, so with the one tap option turned on that means you can unlock an episode every 30 ads you view (it's a bit hard to keep up but I do think it's good to try and get as much chapters on the official site as you can to support the creator since they do get ad revenue from all the ads you'll be viewing)
ah okay, I remember i read this story on some app so i thought it's webcomics, lol
