App Store Opportunity Research

When to Use

Use this skill when the user wants to:

• Find profitable app ideas in a category or niche
• Research App Store charts for underserved opportunities
• Analyze competitor apps (ratings, reviews, revenue, gaps)
• Generate a top-3 opportunity report with revenue validation
• Write a detailed MVP Product Requirements Document (PRD)
• Build a working prototype from the PRD on Rork

Trigger phrases: "find app opportunities", "app store research", "what app should I build", "research this app category", "find a gap in the app store"

Prerequisites

• Chrome browser with Claude in Chrome extension (for App Store browsing)
• Rork account at rork.com (for prototype building, optional)
• No API keys required — all research is done through live browser interaction

Pipeline Overview

App Store Charts → Competitor Deep-Dive → Gap Analysis → Top 3 Report → PRD → Rork Prototype

The entire pipeline can run end-to-end in a single session (~30-45 min).

Step 1: Define the Category

Ask the user what space they want to explore. Help them narrow down:

• Too broad: "Health apps" (thousands of competitors)
• Good: "Sleep + anxiety apps for consumers" (specific intersection)
• Good: "Habit tracking for fitness beginners" (audience + niche)
• Good: "AI-powered journaling apps" (tech angle + category)

Key questions to ask:

1. What category or problem space interests you?
2. Consumer or B2B? (Consumer is easier to validate quickly)
3. Any budget constraints? (No-AI = cheaper to build, AI = higher ceiling)
4. Target revenue? ($1K/mo hobby vs $10K/mo business)

Step 2: App Store Charts Research

Browse the App Store charts in the relevant category using Chrome:

1. Navigate to: https://apps.apple.com/us/charts/iphone/{category-slug}/{category-id}

   • Health & Fitness: /health-fitness-apps/6013
   • Lifestyle: /lifestyle-apps/6012
   • Productivity: /productivity-apps/6007
   • Education: /education-apps/6017
   • Medical: /medical-apps/6020
   • Entertainment: /entertainment-apps/6016

2. Document the top 25-50 apps noting:

   • App name and position
   • Rating count (proxy for install base)
   • Star rating
   • Price/monetization model
   • Brief description

3. Identify patterns:

   • Which apps have massive ratings (>100K)? These are saturated.
   • Which apps have moderate ratings (1K-50K)? Proven demand, beatable.
   • Which apps have low ratings (<500)? Possible new/underserved niche.

Step 3: Competitor Deep-Dive

For each promising niche area, deep-dive into 5-8 competitor apps:

Data to Collect Per App

Revenue Estimation Techniques

• Direct sources: Search "{app name} revenue", "{app name} ARR"
• Proxy calculation: rating_count * 40-80 = approximate installs (rule of thumb)
• Industry benchmarks: 2-5% of free users convert to paid
• Comparable apps: Find similar apps with known revenue

Red Flags (Avoid These Niches)

• Top app has 1M+ ratings (dominated by a giant)
• Category requires hardware integration (Apple Watch data, etc.)
• Heavy regulation (medical devices, financial trading)
• All competitors are free with no monetization path

Green Flags (Pursue These Niches)

• Top competitors have poor reviews (< 3.0 Trustpilot)
• Solo devs making $50K+/yr (proves indie viability)
• "Editors' Choice" app exists with < 20K ratings (Apple promotes the niche)
• Users complain about the same missing feature across multiple apps
• Clear $5-15/mo willingness to pay

Step 4: Gap Analysis

Create a feature comparison matrix across the top competitors:

| Feature | App A | App B | App C | App D | YOUR APP |
|---------|-------|-------|-------|-------|----------|
| Core Feature 1 | Yes | Yes | No | Yes | YES |
| Core Feature 2 | No | Yes | Yes | No | YES |
| Missing Feature | No | No | No | No | YES |
| Price | $14.99 | $9.99 | Free | $6.99 | $5.99 |
| UX Quality | Poor | Good | OK | Good | Premium |

The winning opportunity is where:

1. Multiple competitors exist (proven demand)
2. They all miss the same 1-2 features
3. Users vocally complain about the gap
4. Pricing is high enough to support indie revenue

Step 5: Top 3 Opportunity Report

Produce a ranked report with this structure:

# Top 3 App Opportunities in {Category}

## Opportunity 1: {App Name} (RECOMMENDED)
**One-line pitch:** {What it does in 10 words}
**The gap:** {What's missing in the market}
**Target user:** {Who and why they'd pay}
**Revenue model:** {Price point and conversion assumptions}
**Revenue path:** {How to reach $X/mo}
**Competition:** {Who exists, why you win}
**Build complexity:** {Low/Medium/High}
**Confidence:** {High/Medium/Low with reasoning}

## Opportunity 2: {App Name}
...

## Opportunity 3: {App Name}
...

## Recommendation
{Why #1 is the best bet, with specific reasoning}

Present this to the user and get their pick before proceeding.

Step 6: Write the MVP PRD

Once the user selects an opportunity, write a comprehensive PRD with these sections:

1. Executive Summary — One paragraph pitch
2. Market Opportunity — Problem, market size, competitive landscape table, revenue validation
3. Target Users — 3 personas with name, age, job, pain points, willingness to pay
4. MVP Feature Set — 5-8 feature groups with detailed specs, UI behavior, edge cases
5. Screen Map — All screens listed with parent/child relationships
6. User Flow — Primary user journey from onboarding to daily use
7. Monetization — Free vs Premium feature split, pricing, trial strategy
8. Tech Stack — Framework, libraries, state management, persistence
9. AI Features — If applicable, what AI does and doesn't do
10. Data Models — TypeScript interfaces for core entities
11. Design Direction — Color palette (with hex codes), typography, component style, mood
12. Launch Strategy — Week 1-12 plan, marketing channels, content strategy
13. Success Metrics — KPIs with specific targets
14. Risks & Mitigations — Top 5 risks with solutions
15. Compliance — Privacy, data handling, App Store guidelines
16. Future Roadmap — V2, V3 features beyond MVP

Save the PRD as: PRD-{AppName}.md

Step 7: Build on Rork (Optional)

If the user has a Rork account, build a working prototype:

1. Navigate to rork.com
2. Select model: Opus 4.6 (or latest available)
3. Write the prompt — Condense the PRD into a detailed Rork prompt covering:
   • App name and purpose (1 sentence)
   • Design system (colors with hex codes, card styles, corner radii, typography)
   • Navigation structure (tab names, icons)
   • Each tab/screen with specific UI elements
   • Modal screens with full interaction specs
   • State management approach and mock data
   • Tech stack (Expo SDK, TypeScript, key libraries)
4. Submit and monitor the build (typically 5-10 min, 7-10 steps)
5. Verify the preview renders correctly (Cmd+R if stuck on loading)
6. Share the project URL with the user

Rork Prompt Template

Build "{AppName}" — {one-line description}.

DESIGN: {Theme name}. Background: {color}. Cards: {style}.
Primary accent: {color}. Secondary accent: {color}.
Text: {color}. Corners: {radius}. Effects: {glow/shadow/glass}.

NAVIGATION: {N} tabs — {Tab1} ({icon}), {Tab2} ({icon}), ...

{TAB1 NAME} TAB:
- {Element 1 with full spec}
- {Element 2 with full spec}
...

{TAB2 NAME} TAB:
...

{MODAL SCREEN}:
...

STATE MANAGEMENT: {Approach}. Mock data for {N} days.

TECH: Expo SDK 52+, TypeScript, Expo Router, {styling}, {animations}.

Example Session Output

A complete session produces:

1. Category research notes — charts analysis, competitor list
2. Top 3 Opportunity Report — ranked with revenue validation
3. MVP PRD — 16-section document with full specs
4. Working prototype — live on Rork with shareable URL
5. Go-to-market notes — pricing, channels, launch plan

All in ~30-45 minutes of automated research and building.
