How to Write an App Store Description That Converts
Copywriting techniques for writing an App Store description that ranks well and convinces users to download. Includes real examples and a template.
Your App Store description is read by a small but highly motivated subset of users — people who've already scrolled past your screenshots and want to know more. Write it well and you'll convert the most undecided visitors.
What your description actually does
On iOS, the App Store description is not indexed for keyword search — keywords go in the dedicated Keywords field, App Name, and Subtitle. The description's job is purely conversion: convince users who are already on your page to tap "Get".
On Google Play, the Long Description is indexed for search, so it serves a dual purpose: ranking and conversion. Include your core keywords naturally while still writing for a human audience.
The first sentence is everything
Both stores show only the first few lines of your description before a "Read more" tap. On iOS it's approximately 255 characters. On Google Play it's your entire Short Description (80 chars) plus the first ~167 characters of the Long Description.
Lead with your most compelling benefit — not your app's name, not "Welcome to", not a generic tagline. State clearly what the app does and why it matters.
Use a benefit-first structure
A common mistake is listing features instead of benefits. Features describe what the app does. Benefits describe what the user gets. Compare:
- Feature: "30+ customisable budget categories"
- Benefit: "Know exactly where your money goes — without spreadsheets"
Start every paragraph with a benefit. Follow with the feature that delivers it. This structure is easier to skim and more emotionally engaging.
Format for scanning
Users don't read descriptions — they scan. Use short paragraphs (2–3 sentences max), bullet points for feature lists, and line breaks between sections. The App Store doesn't render markdown, but you can use Unicode bullets (•), dashes, or ALL CAPS section headers to create visual structure.
Include social proof
If you have press coverage, awards, or notable user metrics, include them. A single line like "Featured by Apple · Used by 200,000 developers" dramatically increases trust for new visitors. Place social proof near the top of your full description (just after the hook) and again near the end as a closing signal.
Close with a call to action
End your description with a simple, direct call to action. "Download free today", "Start your free trial", or "Join 50,000 users — free to download". It sounds obvious, but most descriptions trail off without one.
A description template
[Hook — your #1 benefit in one sentence]
[Problem you solve — 2 sentences]
FEATURES
• [Benefit-led feature 1]
• [Benefit-led feature 2]
• [Benefit-led feature 3]
[Social proof — press, ratings, user count]
[Call to action — download free, start trial, etc.]
What to avoid
- Opening with your app's name ("Welcome to AppName…")
- Keyword stuffing — Google penalises it, Apple ignores the description for ranking
- Claiming "#1" or "best" without evidence — it looks spammy
- Walls of text with no line breaks
- Describing every single feature — focus on the 5 most compelling ones
