Tells you whether your idea is a vitamin (nice to have), a painkiller (must have), or a bit of both.
Problem
It's easy to fall in love with an idea for an app, a product, or a side hustle before checking whether anyone really needs it.
Solution
Bounce the idea off it and it calls it vitamin, painkiller, or mixed. If it solves a real pain, it also scores whether people would still be paying for it a year from now.
