What is an ASO launch checklist and why it matters
An ASO launch checklist is a pre-launch app store optimization checklist that audits your app's metadata, visuals and store listing before you go live. The 24-item app store optimization checklist covers keyword positioning, title and subtitle quality, icon legibility, screenshots that show benefit not features, and preview text that hooks users in the first two seconds. Each item is weighted by impact on organic search ranking and conversion, so you know where to spend your effort.
A proper app store launch preparation checklist prevents the most common mistake: launching with a description written for developers, screenshots showing empty states, and keywords that no one actually searches for. Teams that work through a checklist before launch avoid the common fix-it-after-release cycle, where the first week of installs lands on a half-finished listing. App launch optimization on day one is cheaper than trying to fix a weak listing with paid install campaigns later.
What this checklist covers
The ASO Launch Checklist organizes 24 tasks across five launch categories. Each task is weighted by impact on launch success, so your score reflects how prepared you are to ship, not just how many boxes you ticked.
launch readiness score = (sum of completed task weights) / (sum of all task weights) * 100
Task categories and their weights:
- Metadata (name, subtitle, keywords, description, promo): 36 points total
- Creative (icon, screenshots, preview video, accessibility): 30 points total
- Ratings (prompting, response, escalation): 15 points total
- Launch week (timing, announcement, support): 18 points total
- Measurement (tracking, events, cohorts): 27 points total
- Store settings (category, age, language, permissions, testing): 25 points total
Highest-weight tasks (10 points each): app name, store screenshots, install tracking.

Your app name, subtitle, keywords and description are the first lever on visibility and conversion. These are the only things users see before installing (unless they watch your preview video).
- App name (highest impact): Prioritize search intent over branding. 'Fitness Tracker Pro' ranks better than 'FitPro' if your users search 'fitness tracker.' Use the name field, not the subtitle, for high-value keywords.
- Subtitle: Answer what the app does in 30 characters. 'Track workouts, meals and progress' beats 'Your fitness companion.' Test two versions with split screenshots and measure install volume.
- Keywords: Avoid duplication. Use the 100-character field to capture long-tail variations of your main search terms (e.g., 'fitness app,' 'workout tracker,' 'health logging'). Tools like App Annie's keyword research (now part of data.ai) show search volume per keyword.
- Description: Write for both stores (Apple and Google each have their own). Start with value, not features. 'Log workouts in seconds' beats 'Advanced fitness tracking engine.' The first 100 characters are most read; use them to answer why someone should download now.
- Promotional text: Use this to highlight sales, new features or limited-time partner offers. Update it monthly to drive repeat visits from past users and to test messaging before building major features.
Creative: screenshots and icon matter most
Your app icon and store screenshots are your second impression after the app name. They decide whether a user who found your app in search actually taps to install.
- App icon: Test at both 1x (1024x1024) and 3x (3072x3072) sizes. A detail that reads at 3x can disappear at 1x. Use high contrast and colour (avoid thin lines or light-on-light). Look at your competitors' icons; if yours does not stand out in a grid, redesign it.
- Store screenshots: 3 to 5 images with overlaid text showing features, not flow. The first screenshot is most important; it should show your app's core value in one visual. Use real app UI, not mockups, to build trust. Include pricing or free trial callouts if relevant.
- Preview video (optional): Keep it under 15 seconds. Show the app in action, not a demo presenter. Apps with preview videos see higher install conversion than without, but a bad video is worse than no video. Test before launch.
- Accessibility: Add alt text to all images for screen readers. Ensure text on screenshots has sufficient contrast (WCAG AA minimum). This is legally required and expands your addressable market.
Ratings and reviews: the feedback loop
Users install based on name and screenshots. They stay or churn based on the app experience. Ratings are your feedback loop; respond to them fast and fix real issues even faster.
- Prompt strategy: Ask users to rate after a positive action (completed first workout, sent first message, made first purchase). Never ask during onboarding. Apps that time the prompt well see 50% higher rating rates and higher review quality (because satisfied users are rating).
- Response process: Respond to negative reviews within 24 hours. Acknowledge the issue, ask for details if needed, and link to support. This signals to other potential users that you are responsive and helps your app's ranking (Apple and Google both reward developer responses).
- Escalation: Tag recurring issues from reviews (bugs, feature requests, payment problems) and assign them to your product and support teams. A 1-star review is not complaining; it is free market research about what to fix first.
Launch week: visibility and momentum
Shipping the app is day one. The first week determines whether you get organic visibility in search. Plan ahead.
- Soft launch (1 to 2 weeks early): Submit to the App Store and Google Play, but keep your app unlisted. This gives Apple and Google time to index your metadata and run their quality checks. It also gives you time to fix any rejection issues. Once you are listed, your score in the store ranking algorithm is influenced by early installs and ratings; soft launch delays let you gather initial users and momentum.
- Announcement plan: Email list (if you have one), social media posts, PR outreach to tech blogs. The announcement itself does not drive a majority of early installs, but it amplifies the app's signal in the ranking algorithm. Apps with correlated spikes in installs from multiple sources rank better than apps with flat growth.
- Support ready: Have your support email and FAQ live before launch. Users will hit issues; fast responses drive higher ratings and repeat engagement. If your app is a marketplace or has creator content, be ready to moderate and support creators on day one.

Questions people ask
Can I use a launch checklist instead of actual marketing strategy?
No. This checklist gets the foundations right so your marketing (paid ads, organic channels, partnerships) actually has something to work with. A polished app listing does not create demand; it converts demand that already exists. This checklist ensures that when someone finds your app through ads or search, they actually install.
What is the difference between a soft launch and a hard launch?
Soft launch means your app is live on the store but not promoted or announced. You can gather initial users, fix bugs and let the store's algorithm index your metadata before wide announcement. Hard launch means public announcement on day one. Soft launching 1 to 2 weeks early usually produces better long-term ranking because early installs signal quality to the stores.
If I do not complete all 24 tasks, can I still launch?
Yes. Launch readiness is a spectrum, not a binary. A 60% score (metadata and creative done, tracking still setup) is launchable. Some tasks (like ratings strategy or language localization) can be iterated post-launch. But the highest-weight tasks (name, keywords, icon, screenshots, tracking) should be done before you ship.
How often should I revisit this checklist?
Once pre-launch, then monthly post-launch. Use it to track updates to creative (new screenshots for new features), promotional text changes (seasonal offers) and measurement dashboard improvements. Apps that iterate on their store listing typically see 10% to 20% month-over-month install growth as they optimize.
Do I need to translate my app into multiple languages to launch?
No, but you should plan for it. Launching in one language gets you to market faster. If your target market is global, expand to 3 to 5 languages within the first month (prioritize by market size). Translating metadata is often more impactful than translating the app UI initially because users find you through search in their language.
What should I focus on first if I have only a week before launch?
In order: 1. App name and keyword field (search visibility). 2. Icon and first screenshot (conversion). 3. Install tracking (measurement). 4. Store testing on actual device(s). These four cover 60% of launch readiness and can be completed in a week.
Do I need to complete every item on the ASO launch checklist before I launch?
No. The app store launch preparation checklist is weighted. Metadata (title, keywords, description) matters most. Visual completeness (icon, at least 2 screenshots) is next. Preview text and the ratings prompt can follow in the first days after launch. Fix red-flag items; yellow-flag items can ship after launch.
How often should I run the app store optimization checklist?
Run a full app store launch preparation checklist one week before launch, then quarterly after. Every time you add a feature or see a competitor copy your concept, re-check your keywords, description and screenshots to stay relevant.
