App Store Launch Checklist and Timeline

App Store reviews take time. Marketing has to be ready before the app is approved. Here's the timeline that sequences it correctly.

App Store Launch Checklist and Timeline

Most app launches fail not because the app is bad but because the timeline was wrong. Developers submit to the App Store, then start on marketing — not realizing Apple review takes 1-3 days and that your press outreach, social posts, and product hunt submission all need to land the same day the app goes live.

The Problem: Sequencing a Launch Backwards

The most common mistake: developers treat App Store submission as the finish line. They spend months building, submit for review, and then start scrambling to write App Store copy, record a preview video, and email journalists — all while the clock is ticking on the review window.

By the time the app is approved, the marketing is half-done. The launch day post goes out, gets a handful of retweets, and then silence. No press. No Product Hunt push. No email sequence warming up subscribers. The app ships and sinks.

The actual finish line is coordinated impact on launch day. That means your App Store page, your marketing site, your email list, your social presence, and your press outreach are all ready before you submit. gantt-chart.io was built for exactly this kind of multi-track coordination where every dependency matters.

Prerequisites

  • Screenshots device sizes identified (6.7" and 6.5" iPhone minimum, iPad if universal)

  • Email list tool configured (Mailchimp, ConvertKit, Resend, etc.)

App Store Launch Timeline Template

Phase 1: Foundation (8–6 Weeks Before Launch)

  • [ ] Finalize app name and subtitle
  • [ ] Write App Store description (short + long form)
  • [ ] Draft privacy policy and host it on a real URL
  • [ ] Create support URL / FAQ page
  • [ ] Research keywords using App Store Connect Search Ads suggestions
  • [ ] Set up App Store Connect record (bundle ID, capabilities)
  • [ ] Begin producing marketing screenshots (use Figma, Rotato, or similar)
  • [ ] Record preview video (15-30 seconds, no audio required but recommended)
  • [ ] Identify category and secondary category

Phase 2: Marketing Assets (6–4 Weeks Before Launch)

  • [ ] Build or finalize marketing site with clear value prop above the fold
  • [ ] Add "Coming Soon" page or waitlist capture
  • [ ] Write 3-email launch sequence (announcement, reminder, live)
  • [ ] Draft Product Hunt page copy and gather 5+ hunters/supporters
  • [ ] Write 5-10 cold pitch emails for journalists (personalized per outlet)
  • [ ] Create social media assets (launch post, countdown post, demo GIF)
  • [ ] Set up App Store pre-order if targeting a specific date

Phase 3: Submission & Staging (4–2 Weeks Before Launch)

  • [ ] Submit first build for TestFlight external testing
  • [ ] Fix critical bugs from beta feedback
  • [ ] Upload final screenshots and preview video to App Store Connect
  • [ ] Complete all metadata fields (support URL, marketing URL, copyright)
  • [ ] Set up App Store pricing and availability (all regions or targeted)
  • [ ] Submit for App Store review (allow 1-3 days; complex apps may take 5-7)
  • [ ] Prepare Product Hunt submission (embargo until launch day)
  • [ ] Schedule email launch sequence to fire on approval day

Phase 4: Launch Day Execution

  • [ ] Confirm app is approved and listed in App Store
  • [ ] Publish Product Hunt listing at 12:01 AM Pacific
  • [ ] Send launch email to full list
  • [ ] Post on all social channels simultaneously
  • [ ] Send press emails (send these 2 hours before public go-live)
  • [ ] Post in relevant communities (Hacker News, Reddit, Indie Hackers, Slack groups)
  • [ ] Respond to every early comment and review within 24 hours

Phase 5: Post-Launch (Week 2–4)

  • [ ] Monitor App Store ratings and respond to reviews
  • [ ] Check conversion rate on App Store page (impressions → downloads)
  • [ ] Run first paid acquisition test if budget allows
  • [ ] Write "launch retrospective" post for Indie Hackers or your blog
  • [ ] A/B test screenshots if downloads underperform

Common Mistakes

Starting marketing after submission. Review can take 72 hours. That's not enough time to build a press list, write a sequence, or get Product Hunt hunters lined up.

Ignoring the App Store page as a conversion tool. The first screenshot is your hero image. Most developers put a literal screenshot of the app. Designers put a benefit statement over a phone mockup. Test which works better for your audience.

Launching on a Monday. Product Hunt traffic peaks Tuesday through Thursday. Press is harder to get on Mondays (inboxes full) and Fridays (newsrooms light). Aim for Tuesday or Wednesday.

No follow-up plan for reviews. Your first 10-20 reviews determine your initial rating. Prompt happy users to leave a review using SKStoreReviewController after a positive interaction — not randomly on app open.

Skipping pre-order setup. If you have an audience, pre-orders collect conversions before launch and boost your chart position on day one. Most indie developers skip this entirely.

Quick-Start in gantt-chart.io

  1. Go to gantt-chart.io and create a new project called "App Store Launch"
  2. Set your target launch date as the project end date
  3. Add the five phases above as row groups
  4. Add each checklist item as a task with a duration and dependency
  5. Mark submission as a milestone; set review window as a 3-day buffer task
  6. Share the Gantt with your designer and marketing collaborator

FAQ

How long does App Store review actually take?

Most apps are reviewed within 24-48 hours. Apps with in-app purchases, login flows, or new entitlements can take 3-7 days. Plan for 5 days as your buffer.

Should I submit for pre-order or straight to launch?

Pre-order if you have an existing audience to drive conversions before launch day. Skip pre-order if you're launching cold — it splits your momentum.

What happens if Apple rejects the app?

You'll get a rejection reason. Most are fixable within 1-2 days. Build a 7-day review buffer in your timeline if this is your first submission or you're using new APIs.

Do I need a press kit?

Yes. A simple press kit with your logo (SVG + PNG), app icon, 3-5 screenshots, and a one-paragraph description saves journalists time. Host it on a public URL (Dropbox, your site, Google Drive).

How many screenshots do I need?

Apple requires at least one screenshot. You need at least three to fill the preview carousel effectively. Five to eight screenshots is the standard for apps with multiple features.

A coordinated App Store launch is a project management problem as much as a marketing problem. The apps that get covered in press, hit the top charts, and build early momentum aren't necessarily the best-built — they're the best-launched. Map the timeline, set the dependencies, and don't let the review window catch you flat-footed.
