Exact spec references and ASO guides for indie app developers - written to answer the question you actually searched.

Apple’s September 9 event brings iPhone 18 Pro, Pro Max, and a rumored foldable. What that means for App Store screenshot classes — and what you should not guess.

Indies rewrite screenshots after every ship, or never. A practical cadence: after a real product change, after an OS UI shift, when conversion drops, and before a season.

From September 2026, App Store Connect requires social-media capability answers before you can submit an update. What counts as a feed, what a share button is not, and the 13+ floor.

Organic ranking takes weeks to settle. September is the last clean window before Halloween and holiday search. What to change this week.

Apple search shows up to three frames before anyone opens the page. Play often leads with screenshot one. What each of those slots is for.

The stores look similar. Indexed fields, screenshots, descriptions, and ranking signals are not. One checklist per store.

Play indexes the 80-character short description and shows it on search cards. How to write one that ranks and still reads like a human.

A start-to-finish workflow: capture real UI, write captions, frame at exact sizes, export without alpha, and upload in App Store Connect.

Apple gives you 100 hidden characters. Most indies waste 20–30 of them repeating the title. How to format, what to skip, and worked examples.

Play announced memory, bitmap, and 25% DEX optimization thresholds on Aug 26, 2026. Enforcement starts February 2027. What indie apps actually have to change.

Grok Bot is xAI’s always-on agent with a cloud computer. Indie app teams use it for research and caption drafts, then finish App Store screenshots and icons in AppGrowthKit — the store-sized export Grok Bot does not have.

There is no standalone Grok Bot SKU. Access is bundled into named SuperGrok and Cursor plans, weekly usage is included, and extra work bills from model and token cost. Here is the indie-readable map.

Get Grok Bot from x.ai/bot — not a random GitHub mirror. Desktop is macOS and Windows. The companion app is iPhone on iOS 18+. Linux, Android, and iPad are not supported at launch.

ChatGPT is the default writing and reasoning surface. Grok Bot is xAI’s bet that the answer should land in the signed-in tool, on a computer that stays on after you close the laptop. For App Store work, neither one is the screenshot exporter.

Create one specialist Bot, give it a closed-ended ASO job, then paste the surviving captions onto real app screens in AppGrowthKit and export store sizes.

Prompts that treat Grok Bot like a contractor: closed-ended ASO research and caption drafts you paste into AppGrowthKit — plus hard stops so it never invents app UI or publishes to Connect.

It can research competitors, draft 3–7 word captions, and even click around a browser. It cannot be the source of the in-app UI, and it does not ship a store-accurate export pack. Here is the split that survives review.

Grok Bot is a strong overnight ASO researcher: competitor teardowns, keyword shortlists, subtitle options. AppGrowthKit turns the surviving copy into store-sized screenshot sets. Keep Connect as a human step.

Grok Bot’s iPhone companion is iOS 18+, syncs threads with desktop, and has to sell an always-on computer you cannot see on a 6.9″ screen. That is a listing problem every agent-app founder is about to have.

If you already pay for Cursor Pro+ or Teams, Grok Bot is sitting in the same family of seats. It can replace overnight research, inbox triage, and first-draft listing copy. It does not replace TestFlight, App Review, or a screenshot exporter that knows store pixels.

Since April 28, 2026, App Store uploads must use the iOS 26 SDK. Standard bars and sheets pick up Liquid Glass on their own. If the listing still shows last year’s opaque chrome, the product page is advertising an app you no longer ship.

Most “ASO screenshot” rejections are not a taste debate. They are Guideline 2.3: the frames do not match the binary, the splash is doing the talking, IAP is hidden, or the metadata would fail a 4+ check. Here is the indie checklist.

Apple will show a Custom Product Page in App Store search when you assign keywords to it — instead of your default listing. That is not an ads-only feature. It is extra screenshot sets aimed at extra jobs, and most small teams never ship the second set.

Google Play will ship a listing with two screenshots. The large recommendation surfaces that actually use screenshots ask for four frames at 1080px or larger. That gap is how indie Android apps stay live and stay invisible.

Since July 22, 2026, Google Play can share your US name, icon, description, screenshots, and videos with enrolled third-party Android stores. Here is what that means for indie teams and how to keep the listing honest wherever it appears.

From July 2026, Play store listing reports count unique Install, Open, and Pre-register clicks instead of completed acquisitions. Here is how indie teams should read CTR, keep experiments honest, and improve the listing assets that actually drive the tap.

Google is expanding the Play Age Signals API from Brazil to Australia and Canada, then worldwide later in 2026. Here is what the privacy-preserving age range actually is, what you may not use it for, and how the store listing has to match the in-app experience.

Texas SB 2420 started applying to new Apple Accounts on June 4, 2026. Apple’s Declared Age Range API, Significant Change API, and consent notifications are how indie apps request an age category without collecting a birthday. Here is a practical path that also keeps the product page honest.

App Store Tags are glanceable terms generated from your App Store Connect metadata, large language models, and human review. They already show in US search and on the product page. Here is how indie teams should manage them — and why screenshot copy is part of the input.

Google Play raises its annual target API bar on August 31, 2026. Here is what API 36 changes for new uploads, existing visibility, large-screen layouts, and the last tests worth running before you ship.

Android developer verification now reaches Play Console and Android Developer Console. Most Play developers are already close to done, but every indie team should check package registration before the September 30 rollout begins.

Google Play discovery is moving beyond the keyword box. Gemini, Ask Play, full-screen video, custom listings, and re-engagement surfaces reward a listing that can explain one real customer outcome clearly and consistently.

Apple’s new Retention Messaging will let subscription apps show a value reminder, image, or offer at the moment someone cancels. Here is how an indie team can prepare a helpful cancel-flow message without designing a dark pattern.

Apple’s new Creative Assets go live on the App Store this fall. Here is what they are, where they appear in iOS 27, how Asset Library works, and how to prepare headers and search art without throwing away your screenshots.

iOS 27 Time Allowances sort apps into Entertainment, Games, and Social Media. The age-rating questionnaire now asks about social capabilities — and from September 2026 you cannot submit an update until you answer.

A practical launch plan for indie app developers: get your listing compliant, make screenshots convert, recruit useful early feedback, then improve with evidence instead of post-launch guesswork.

How to test a Play Store icon, screenshots, feature graphic, or video without fooling yourself with a tiny sample or a muddy hypothesis.

A practical localization workflow for App Store and Google Play screenshots—how to choose markets, adapt the promise, handle text expansion, and QA every frame before upload.

A practical formula for App Store screenshot captions: match the searcher’s intent, lead with a benefit, and stay readable before the UI ever gets a chance to explain itself.

The exact 1024×500 Google Play feature-graphic spec, plus the content rules, cutoff zones, video overlay considerations, and a practical design checklist for a banner that still reads on a phone.

The current App Store preview requirements in one launch-ready checklist: duration, file size, codecs, accepted resolutions, upload limits, and the creative rules that keep your demo honest.

Indie devs on X keep saying the same thing: designing App Store screenshots takes forever. Here’s a practical AI workflow that ships store-ready frames in minutes - without Figma babysitting.

How Product Page Optimization (PPO) and Custom Product Pages work on the App Store - what you can A/B test, how to read results, and how to ship screenshot variants that actually move conversion.

How to design App Store and Google Play screenshots that convert - first-three rules, captions, storytelling, localization, and what to avoid in 2026.

Exact character limits for every App Store Connect and Google Play metadata field - name, subtitle, keywords, promo text, descriptions - plus how to use each one.
Every required app icon dimension for iOS, iPadOS, Android, Google Play, and the density buckets Xcode and Android Studio still expect - plus the format rules that cause rejection.

Every required and optional screenshot dimension for iPhone, iPad, Mac, Watch, Apple TV, Vision Pro, and Google Play - straight from Apple and Google's current specs.
