Read the gaps in order
Fix anything that could mislead a buyer or block a purchase first: broken links, unclear edition differences, unsupported compatibility claims or a missing support path. Then work on polish and promotion.
Indie app / pre-flight
Launch with fewer surprises.
Check the work around the build: who it is for, what the store page says, how support works, what data moves and how you will learn from launch.
Your launch checklist
Check only what is ready now. Unchecked items become your next-work list, not a reason to panic.
Your readiness snapshot
Keep the first measurement simple
Count the steps you can actually observe: relevant page visit, App Store or checkout click, and confirmed purchase where the provider makes that available. A click is interest, not a sale.
