Don't call a your product 'lame' just because it is simple.
Making it good as you did is nothing but 'that' simple, maybe your experience make you think it is the natural way to go but not everyone follow that way.
And don't be ashamed that such a product doesn't trigger any real technical challenge. Be proud of it.
That's normal. Just because you're good doesn't mean all your competitors are, though. There's a name for that that I can't remember, but the simple fact is that you can carve out market space even with substantial competition. You only need to distinguish yourself by competence, responsiveness, honesty and transparency and ethical dealings. imho, that's the key.
