What it does

App Icon Optimization is an agent skill from appeeky/aso-skills. When the user wants to design, test, or improve their app icon to increase tap-through rate and conversions in App Store search and browse. Use when the user mentions "app icon", "icon design", "icon A/B test", "icon variants", "tap-through rate", "icon conversion", "icon refresh", or wants to know what makes a good app icon. For screenshot optimization, see screenshot-optimization. For full listing A/B tests, see ab-test-store-listing.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Marketing & SEO, covering A/B testing and App store release. The repository describes itself as: AI agent skills for App Store Optimization (ASO) and app marketing. Built for indie developers, app marketers, and growth teams who want Cursor, Claude Code, or any Agent… The licence is MIT.

When your agent uses it

Wants to design
Improve their app icon to increase tap-through rate and conversions in App Store search and browse
The user mentions app icon
Tap-through rate

Example prompts

“app icon”
“icon design”
“icon A/B test”
“/app-icon-optimization”

What it can do on your machine

Read from SKILL.md and the folder at commit 3919d7c. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

App Icon Optimization loads about 1.5k tokens when it runs. Until then it costs about 116 tokens; SKILL.md has 597 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~116
When it runs · the whole SKILL.md, loaded when a task matches: ~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

App Icon Optimization

You help design, audit, and A/B test app icons to maximize tap-through rate (TTR) — the percentage of users who tap your app after seeing it in search results or browse.

Why the Icon Is Your Most Impactful Asset

The icon is the first thing users see in search results — before the title, rating, or screenshots. A compelling icon can lift TTR by 20–40% with no other changes. In browse/charts, it's often the only visual element competing for attention.

Icon Design Principles

1. Simplicity at Small Size

Icons render at 60×60pt (iPhone search results). At that size, detail disappears.

Maximum 2 elements
No text (illegible at small sizes; Apple discourages it)
Strong silhouette recognizable at a glance
Test at 60×60px before finalizing

2. Color Contrast Against the App Store Background

The App Store has a white/light background (light mode) and dark background (dark mode).

High contrast on both modes
Avoid white icons — they disappear in light mode
Avoid very dark icons — they disappear in dark mode
Consider adding a subtle shadow or border on your icon background

3. Category Visual Language

Match and differentiate from your category norms:

Category	Common patterns	How to stand out
Productivity	Blue, clean, minimal	Warmer colors, bolder marks
Health/Fitness	Green, orange, energetic	Premium dark, sophisticated
Finance	Blue, green, conservative	Bold, distinctive mark
Games	Bright, characters, action	Premium/dark if competitors are loud
Social	Round shapes, soft colors	Sharp, distinctive if feed is soft
Meditation	Purple, blue, calm	Unexpected contrast color
Photo/Video	Gradient, camera	Single strong mark

Rule: Look at your top 20 competitors' icons. Then design to be immediately distinguishable.

4. Recognizable Mark

The icon needs a single, memorable mark — not a scene or a composition. Ask:

"Can someone describe this icon in 3 words?"

✅ "Red speech bubble" | ❌ "Someone using a phone with a gradient"
✅ "Bold orange flame" | ❌ "Abstract colorful shapes"

5. Brand Consistency

The icon is your brand mark in the App Store. It should:

Match your app's primary color palette
Be consistent with your splash screen, push notifications, and marketing
Work as a favicon, social media avatar, and press kit asset

Icon Sizes Required

Platform	Size
iPhone (App Store)	1024×1024px (master)
iPhone (home screen)	60×60pt @1x, @2x, @3x
iPad	76×76pt @1x, @2x
Watch	40×40pt – 44×44pt
Android adaptive icon	108×108dp (safe zone 66×66dp)

Submit a single 1024×1024px PNG (no transparency, no rounded corners — Apple applies the mask).

A/B Testing Icons

iOS — Product Page Optimization

App Store Connect → Your App → Product Page Optimization → Create Test
Create up to 3 icon variants
Set traffic allocation (20–33% per variant)
Run for minimum 7 days or until statistical significance

Access: App Store Connect → App Store → Product Page Optimization

Android — Play Store Experiments

Play Console → Store listing experiments → New experiment
Upload up to 3 icon variants
Set traffic split
Google reports install conversion rate per variant

What to Test

Test one variable at a time:

Test	Variants
Color scheme	Same mark, 3 different background colors
Mark style	Flat vs illustrated vs 3D
Dark vs light	Dark background vs light background
Character vs abstract	Character-based vs geometric/abstract
With vs without text	Mark only vs mark + short text

Reading Results

Primary metric: Install conversion rate (impressions → installs)
Minimum sample: 1,000+ impressions per variant for reliable signal
Significance threshold: p < 0.05 or Appeeky/Play Console confidence indicator

Icon Audit

Evaluate your current icon against:

Clarity at 60×60px:        [1–10]
  - Recognizable mark at small size?
  - No illegible text?

Color contrast:            [1–10]
  - Works on white (light mode)?
  - Works on dark backgrounds (dark mode)?

Category differentiation:  [1–10]
  - Stands out from top 10 competitor icons?

Simplicity:                [1–10]
  - Max 2 elements?
  - Describable in 3 words?

Brand alignment:           [1–10]
  - Consistent with app's visual identity?

Overall: [N]/50

Brief for Icon Designer

When briefing a designer:

App: [name and one-line description]
Category: [category]
Primary audience: [who uses it]
Brand colors: [hex values]
Mood/feeling: [premium / playful / trustworthy / energetic / calm]

What the icon should convey: [core value or identity]
What to avoid: [don't replicate competitor X, avoid Y]

Competitors to differentiate from: [list 3–5 with icons]
Reference icons I like: [list 3–5 from other apps]

Deliverables:
- 3 distinct concepts at 1024×1024px
- Each concept tested at 60×60px mockup in App Store search context
- Final: PNG, no alpha, no rounded corners

ab-test-store-listing — Full A/B testing methodology
screenshot-optimization — Complement the icon with strong screenshots
android-aso — Android adaptive icon requirements
aso-audit — Icon is one factor in the full ASO score
