I just got off a 30 minute Zoom call with a marketing research guy and he called this "Qualitative Research". Walk through your idea with 5 to 7 people one at a time, improving each time. Do this _before_ you even write any code. You'll save yourself a ton of time, though this is harder to do...because you actually have to find people within your target market and induce them to work with you. A $25 Amazon Gift Card might just be the trick. Once you've iterated and your interviews tighten up, you know you're ready to design and build. Then you have to go through it all over again to validate it or pivot.
