Launch an iPhone app people can understand
An iPhone App Store launch and ASO guide covering the app record, metadata, screenshots, previews, testing, privacy, review, release, and post-launch learning.
In brief
A strong iPhone launch joins a release-ready product to a truthful store promise. Build the app record and privacy details early, design a legible screenshot argument around real product value, test the signed build on supported devices, then measure activation and retention alongside product-page conversion.
On this page
Build the launch foundation before writing copy
Create the App Store Connect record early enough to discover account, agreement, identifier, privacy, age-rating, pricing, tax, territory, and role problems before release day. The listing can only promise what the signed build reliably delivers.
Name the first customer
Write down the person, situation, and job the first release serves. “Everyone” cannot guide a launch page.
Choose one outcome
The name, subtitle, first screenshot, and onboarding should reinforce one honest reason to install.
Collect real product states
Prepare believable data, permissions, edge cases, purchase access, and support paths before capture day.
Privacy answers should represent the released app and its SDKs. Accessibility labels should be based on completing common tasks on the device, not on the presence of isolated accessible controls.
Write an App Store listing with distinct jobs
Apple App Store
App name
30charactersLocalized and editable only when the app version status permits it.

Subtitle
30charactersA concise summary shown beneath the app name.

Promotional text
170charactersConversion copy that can be updated independently of a new version.

Keywords

Description
4000charactersVisible product-page copy. The first sentence should explain the product before the text is expanded.

What’s New
4000charactersCustomer-facing release notes for the version being submitted.
Official source ↗Use the app name for a distinctive identity and essential context, the subtitle for a clear use or outcome, and the private keyword field for relevant search language not already carried efficiently elsewhere. Promotional text is conversion copy that can change without a new app version; Apple does not describe it as a search-ranking field.
The description should open with the app, audience, and concrete outcome, then explain the real workflow and inspectable features. Avoid keyword repetition, implementation vocabulary, unverifiable superlatives, and promises the first session cannot keep.
Draft and count the iPhone metadataMake the screenshot sequence a one-second argument
Apple allows 1–10 screenshots per supported display size and localization. Under the current screenshot specification, an iPhone app needs at least one screenshot for the required “iPhone with Dynamic Island (medium display)” set. If the app supports iPad, the required iPad set also applies.
- 01Frame 1 — the outcome
Name the primary value in language a qualified customer can recognize immediately.
- 02Frame 2 — the mechanism
Show the core product interaction with enough real UI to make the claim credible.
- 03Frame 3 — the differentiator
Prove the behavior or quality that makes this product meaningfully different.
- 04Frames 4–6 — the objections
Answer the questions that block install: setup, depth, privacy, compatibility, ownership, or continuity.
- 05Final frame — the right next step
Close with trust or breadth, not a generic download command.
App previews are optional, with up to three per supported device size and language. Use video when motion, gesture, sequence, or transformation materially improves understanding. Design it to work from the first frame and without sound.
Validate the product-page promise in the release build
- 01Test compatible devices
Exercise the signed release build on real supported devices and current operating systems where practical.
- 02Test first-run reality
Fresh install, permissions denied, poor network, empty states, sign-in, purchase, restore, and offline behavior should all be coherent.
- 03Audit every claim
Match names, screenshots, captions, subscription terms, privacy statements, and feature availability to the shipped build.
- 04Use TestFlight deliberately
Give testers jobs and questions; do not treat a large invite list as evidence of coverage.
- 05Prepare review access
Supply a working account, exact steps, hardware dependencies, gated features, and purchase context in review notes.
Submit and release without an avoidable surprise
Attach the build, complete required version information, add the version to review, then submit it. Reconfirm agreements, pricing, tax category, territories, export compliance, content rights, age rating, privacy, and release method. Apple notes that approved releases can take up to 24 hours to appear.

Read the launch as a connected journey
Track impressions and product-page conversion by source, territory, device, and version—but read them beside onboarding completion, activation, purchase quality, retention, reviews, refunds, support, and crashes. A higher install rate is not a win when the listing recruits the wrong expectation.
Once the baseline is stable, use Product Page Optimization for a bounded test of the default product page and custom product pages for genuinely different audience promises. Treat App Store tags as Apple’s taxonomy—not as copy you can force—and ask for ratings only after an earned moment in the product.
