That's right. And Dev is a lazy teenager and only take money and does not do his job which is development of his app.
Eight years and still waiting, Wow. Just Wow.
The developer has a full-time job, and does MX on the side. We should all be grateful that he is willing to spend his extra time creating such an excellent app, with performance that has few peers. Literally millions have benefited from downloading his free and paid app from the Play Store; just look at the app-download statistics on Google Play.
You are a consumer, and you should do all of your research before making a purchase. If you make what is a bad purchase in your eyes, that is your own fault, and no one else is to blame. "Buyer's remorse" is not a legitimate reason to ask for a refund... especially one so many years down the road.
There's a reason the phrase "buyer beware" exists. You made a purchase. At the time, you deemed it to be the right purchase. You no longer think so anymore, so are feeling remorse about it. That's something you deem as a loss, and one that you will have to write-off yourself.

EDIT: kuromusha38 said: "and does not do his job which is development of his app." <-- I would like to add that the developer has no obligation to anyone to meet any of your demands, or anyone else's demands. It's called a "Feature
REQUEST" for a reason.
