A one-page decision for builders who froze on the paywall — plus five category examples so you don’t copy a habit app onto a flashlight.

Q1 — value in 20 seconds?
Q2 — does it need a loop?
Q3 — will they still have this job in 90 days?
Q4 — paid traffic?

You leave knowing hard, trial, or annual-first, and what “fail” looks like in 7 days.

Never run two walls on day 1. Pick, ship, measure paywall_view → purchase.

The full layer (listing, onboarding, paywall copy, web checkout, emails, pushes, five stealable products) is Dock Bench — $47.
Ship this week + first Monday month: Dock Kit — $67.
