Put it into practice
- Identify the primary reason someone would use the app.
- Capture a representative completed state.
- Review the first image without relying on later slides.
What this looks like
A habit app opens its sequence with a useful daily view rather than a sign-in form.
A detail to keep clear
A benefit claim should match the app behavior shown in the screenshot.
Using MockupX
Store specifications are maintained by Apple and Google and can change. Check the relevant console's current requirements for the device family and asset type. MockupX creates images; it does not submit listings, validate every policy or guarantee approval.
Check the result
Keep the original screenshot, then review the exported file at the size where people will see it. Check the message, the visible interface and the final crop separately. For a handoff, record the destination and the approved file so another person can distinguish the final version from a draft.
References and further reading
Use the official references for format behavior and current destination requirements. The composition advice above is a practical design approach, not a promise of platform approval.
