intro.md

For indie apps, organic App Store search is the only free distribution channel — and ASO (title, subtitle, keyword field, description) decides whether you rank. Most indie devs spend months on the app and 20 minutes on the listing. This prompt builds the full ASO package calibrated to real searcher behavior, for App Store and/or Play Store.

The prompt — copy & paste

prompt.txt

You are an ASO (App Store Optimization) specialist who's ranked indie apps in the top 10 for competitive terms. Build the full store listing.

INPUTS:
- App name: {{app_name}}
- What it does (core function + the one job it nails): {{what_it_does}}
- Target user (who, the moment they'd search for this): {{target_user}}
- Platform: {{platform}} (iOS / Android / Both)
- Main competitor: {{main_competitor}}

PRODUCE (note iOS vs Android differences where they matter):

1. KEYWORD RESEARCH
10 search phrases your target user would type in the store. For each: volume (hi/mid/lo), competition, intent match. Pick the top 5.

2. APP TITLE
- iOS: 30 chars. Format: "{{app_name}}: [primary keyword]"
- Android: 30 chars (title) — Google indexes the title heavily
Give the title + reasoning.

3. SUBTITLE (iOS) / SHORT DESCRIPTION (Android)
- iOS subtitle: 30 chars, packed with the #2-3 keywords + benefit
- Android short description: 80 chars, the elevator pitch + keywords (Google indexes this)
Give both.

4. iOS KEYWORD FIELD (100 chars)
The hidden 100-char keyword field. Comma-separated, no spaces, no repeats of words in the title/subtitle, singular forms (Apple matches plurals). Maximize coverage. Output the exact string + char count.

5. DESCRIPTION
- iOS: first 3 lines are critical (above "more"). Hook + top benefits. Then features as benefit bullets. Android: keyword-rich (Google indexes the full description) but readable.
- Structure: hook → who it's for → key benefits (bulleted) → social proof line → CTA
- 600-1000 chars for the visible/important part.

6. COMPETITOR GAP
Based on {{main_competitor}}: one positioning angle they ignore that my listing should own.

7. SCREENSHOT CAPTION IDEAS
5 caption overlays for the screenshots (the captions sell more than the app name).

Be specific to {{platform}}. iOS ranks on title+subtitle+keyword field; Android ranks on title+short+full description.

Step-by-step playbook

How to actually use this prompt for the best results.

01
Set up the listing BEFORE you launch, not after
ASO compounds — the sooner your keywords are live, the sooner you accumulate ranking signal. Build the listing the day you start dev using the keyword research, not the week you ship.
02
Verify keywords in the actual store search
Type each of the 5 focus keywords into the App Store / Play Store search bar. Check autocomplete suggestions and how strong the top apps are. Swap any keyword dominated by household-name apps for a winnable long-tail.
03
Max out the iOS 100-char keyword field
Don't waste a single char: no spaces after commas, no plurals (Apple matches them), no words already in your title/subtitle. The prompt builds this — paste it exactly into App Store Connect.
04
Caption your screenshots — they convert more than the title
Most installs are decided by the first 2-3 screenshots + their caption overlays, not the description. Use the 5 caption ideas to turn screenshots into a benefit story.

$ man tips

Pro tips for better output

›iOS and Android rank differently: iOS uses the hidden keyword field; Android indexes your full visible description. Optimize each platform's listing separately — don't copy-paste.
›Rank for 2-3 winnable mid-volume terms rather than chasing one giant head term you'll never crack as an indie.
›Re-test your subtitle every few weeks early on — it's the highest-impact field you can change without a full app update.

$ man faq

FAQ

Does ASO actually move installs for indie apps?

It's the #1 free lever. Organic store search is where most indie installs come from (paid UA is brutal for solo devs). Ranking top-5 for even a mid-volume term can be the difference between 5 installs/day and 500.

iOS or Android first for ASO effort?

Optimize whichever platform you're launching on first — but note iOS users monetize 3-5× higher (paid apps + subscriptions), while Android wins on volume in many markets. Match your ASO depth to where your revenue is.
