I want to design a widget to sell on the play store but do not have experience. Is there something I can use to create what I want that doesn't require coding knowledge?

Most apps seem to be written that way - which is why there are so many terrible apps. Can you make a 12 course feat fit for a king without learning how to cook? Sure. If you don't mind people gagging on your food.

If you don't understand the environment you're writing for, you come up with something like an app that "cleans" "unused" apps from RAM. That's great in Windows, but it totally destroys responsiveness (and battery) in Android.

I earned my living writing code (not simple stuff - operating systems and up from there) for over 40 years. Android? I modified a sample app that comes with the development kit. Coding was no problem, it's all Java and xml, and I can read and write them as easily as I can read and write English. But how do you put text on a screen in Android? I have no idea. Which is why I refuse to write an Android app. If and when I learn the environment, I'll come up with apps all over the place, but for the moment, even though I can hard-brick my phone without a care (it's a waste of 10 minutes to put it back to where it was), I won't put out the pure garbage I know I'd put out if I wrote an app or widget.

If you want to do programming, you have to learn programming. You can't do what you don't know how to do. (Yes,m you can use one of these "drag&drop controls, check a few boxes" app generators, but you'll try to hide when you see the comments you get.)
