Generating… usually about a minute.
What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

Stop building cool products for empty rooms. Find what people actually pay for, then build it, right here. AppScout gives you the market research to find exactly what to build next, then builds it for you. Open it and immediately see estimated revenue for apps across both major app stores. Not projections, real estimates on real apps, updated regularly. Data over vibes: this is your unfair advantage. Tap any app for the full picture: - Estimated monthly revenue and growth trends - Download trends and velocity over time - User ratings and exactly what people complain about - Competitor analysis against every app in the category - Complete developer portfolios - Geographic breakdown of revenue Some of these apps earn serious passive income despite terrible design. Some haven't been updated in a year. Some have millions of users but barely monetize. Each pattern is an opening, and AppScout surfaces them automatically, so you find what to build before the category gets crowded. Automated discovery: Don't browse the top charts — they're full of VC-backed incumbents. Pick a lens and let the opportunities come to you: - Apps earning well but frustrating their users - Profitable apps not updated in months - New apps gaining traction before the category crowds - Large audiences with almost no monetization - Significant revenue with barely any visibility - Fresh launches showing early momentum - Tiny user bases generating outsized revenue Every result is scored and ranked. Build your own lenses with custom filters when you want full control. AI-powered vibe checks: Found a target? Tap to chat with AI about the niche: "What's the obvious missing feature here?" "Summarize the biggest pain point in the negative reviews." "Is this a solo-dev friendly niche?" Get structured competitor analysis instantly — estimated revenue, gaps, and what users actually want. Let AI read the tea leaves while you decide what to ship. Then build it — right here: This is the part that changes everything. Found a winner? You don't need to open Cursor. Tap Build, and AppScout turns the opportunity into a real, working app, yours to ship. No blank editor, no weekend lost to setup. The research that used to stop at "what to build" now ends with the app already built. Deep market intelligence: Every app opens a door to deeper research: - Revenue and download history — monthly trends over time - Install velocity — daily downloads with trend detection - Review analysis — sentiment breakdown, star distribution - Competitive landscape — every app in the category ranked - Category insights — how saturated a market is, and where the gaps are - Developer profiles — full portfolio analysis - Geographic data — where revenue concentrates globally Set alerts and build: Set up monitoring on any lens. AppScout scans automatically and pushes alerts when new opportunities appear or revenue shifts, so the next thing to build comes to you. Your market research, on autopilot. Powerful search & filters: Know exactly what you're looking for? Filter millions of apps by: - Estimated Monthly Revenue - Download Velocity - User Ratings & Review Count - Update Recency and many more. Combine filters to uncover the exact opportunities no one else is seeing. Both major app stores, one place. Whether you're hunting your first niche, planning your next build, or sizing up the competition, the data is here, and now so is the build. You know how to build. Now you don't even have to.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
