The Smallest Useful App Launch Assets Checklist
A practical app launch assets checklist for indie developers: define the promise, build the page, prepare store copy, create proof and write one clear announcement.

The launch asset list for an indie app can become a second product. You start with a landing page, then add screenshots, social images, a press kit, a video, an email, a changelog and a dozen different versions of the same sentence.
The better approach is to create a small coherent set. Each asset should make the same product easier to understand.
1. Write the product brief first
Before opening a design tool, write one sentence that includes the person, the job and the moment they need it. “A private Mac app for founders who want to review Search Console once a week” is more useful than “the future of SEO.”
Add three boundaries:
- what the app helps someone do
- what it deliberately does not try to do
- what the first useful session looks like
That brief becomes the source material for every later asset. Palm is designed around this move from one sentence to a usable product and launch direction.
2. Turn the brief into a page
The page needs to answer four questions in order: Is this for me? What does it help me finish? What does it look like? What should I do next?
Put the job and audience near the top. Show a real interface or a concrete example before the page becomes a wall of claims. Explain the first useful workflow, then answer predictable questions about privacy, pricing, setup and platform.
3. Prepare store copy as a sequence
The title, subtitle, description and screenshot captions should feel like one conversation. The first screenshot should not be a decorative welcome screen if the buyer really needs to see the outcome.
Write captions that move from problem to workflow to result. The store page is not a feature inventory; it is a compressed explanation of why this app deserves a place on the device.
4. Make one launch message
The announcement only needs to say what changed, who it is for and where to try it. Include one link and one specific reason the app may be useful today.
The strongest launch messages often sound like a personal note: “I built this for the weekly moment when…” That language is more memorable than a list of adjectives.
5. Keep the asset set connected
The page, screenshots and announcement should use the same nouns. If the page says “weekly review” and the store says “analytics command centre”, the reader has to translate the product before they can judge it.
