It depends. If you don't know how to code and you're commenting on language or framework choice (e.g. "it's electron therefore bad") or something like that, then your opinion is probably invalid. On the other hand, if you're comment is something like "This app doesn't work like I want" then it really doesn't matter if you have the slightest idea how to implement what you want. Likewise, a non-designer offering opinions on design philosophy or alternate styles is probably pretty useless. A non-designer saying the thing is awkward/ugly/confusing/whatever is informative though.
