This list complements the full testing checklist. That one covers what to test; this one covers whether you are ready to ship. Store requirements change, so wherever an item touches a store rule, read the current policy page before you submit; the pages used for this list are in the sources.

Why
How to check
1
The core task works start to finish on a clean install
If this fails nothing else matters
Install fresh, do the main task without help
2
Onboarding gets a new user to value quickly
A confusing first session is where you can lose new users
Watch one outsider use it, silently
3
Empty states have text, not blank screens
New users see empty states first
Log in with a new account and open every tab
4
Offline and bad network behaviour is defined
Phones lose signal
Switch to airplane mode mid-action
5
Permissions are requested at the moment of need, with a reason
Early prompts get refused
Walk through every prompt on a new install
6
Account deletion/sign-out works
Users expect to leave cleanly, and both stores have rules for apps with account creation
Print or copy it, answer each row with Yes / No / Not applicable and a date. Any No on items 1, 7, 10, 11, 18 or 19 is a stop. Everything else is a judgment call: write down why you accept the risk.
For a last outside look before launch day, AppReviewX offers private, structured feedback from other developers (1 feedback = 1 credit; new accounts start at 0), plus test groups for Google Play's closed-test requirement (12 testers, 14 days in a row, Android apps). Get started on AppReviewX.
