YOUR INPUTS
Build your result
Complete every field. The result updates only when you choose Calculate.
How it works
Add auth and settings needs
Sign up, log in, and settings screens are added only if the journey needs them.
Check leanness
The score flags when the total screen count exceeds a lean MVP range.

Frequently asked questions
Should every journey get its own inventory?
Yes — run this per critical journey rather than trying to inventory the whole product at once.
What if I need more screens later?
That's expected. This inventory is for the first release, not the final product.
Does this replace wireframing?
No. It tells you what to wireframe, not how each screen should look.
