Source proof

See exactly what Review Radar found.

Review Radar preserves the exact public review text, Apple review ID, source app, fetch date, and Apple source links before it generates an idea.

Ten source apps

Review browser

Read all 100 retained reviews.

Why Apple may look different: the App Store page is a storefront view, not a permanent list of every review. Review Radar preserves all returned records here. Each row includes the exact Apple feed page that supplied it and the Apple review ID to search for inside that feed.

How to verify a returned review

Find it on Apple in two steps.

Try the storefront page first. Open “Browse this app's storefront reviews.” Confirm that its country matches the storefront code shown on the review. Open all Ratings & Reviews and load more reviews if Apple offers that control. Then use Find in Page: Command-F on a Mac, Ctrl-F on Windows, or your mobile browser's Find in Page command. Search for the review title, author, or a distinctive phrase.
If the storefront does not show it, verify Apple's source record. Open “Verify in the exact Apple source feed.” The feed may look like raw text. Use Find in Page for the Apple review ID shown on the Review Radar record. That exact feed and ID are the source Review Radar retained.

Apple's public product pages vary by country or region and do not reliably surface every review in one web view. The exact source feed and review ID provide the reliable fallback.

Next step

Use this evidence to strengthen the idea.

When you supplied an idea, it remains the primary hypothesis: the evidence sharpens it instead of replacing it. The reviews stay available if generation fails, so you can retry without fetching them again or using a Blueprint credit.

Ready to build this one?

Turn the concept into the complete project your AI can build.

The preview shows the product direction. One Blueprint credit creates the full implementation package: the complete high-resolution screen system, exact design tokens and behavior contracts, review evidence, product strategy, full-stack architecture, backend schema, step-by-step build prompts, visual comparison tests, beta and publishing instructions, marketing, support, and post-launch operations.

Download one organized folder, open that whole folder in Codex, Claude, Cursor, or another coding agent, and paste the included starting prompt. The agent is told what every file means, which user journey to build first, how to work from interface through backend, and how to prove the running product matches the approved screens.

No user, download, revenue, or business outcome is promised. The product is a tailored evidence, design, architecture, and operating package for you and your AI coding agent.

Know what happens before you begin

Clear answers. No technical background required.

What happens during a free crawl?

Review Radar finds ten relevant App Store products, retains 100 public reviews, and shows you both the evidence and several app opportunities based on repeated customer praise and complaints. You can run unlimited new searches and regenerate ideas from the same evidence without paying.

What do I receive after I use a Blueprint credit?

You receive one organized, downloadable project folder tailored to the app you chose. It includes the complete first-release screen system, design rules, product scope, full-stack architecture, backend data model, sequenced build prompts, QA checks, beta and publishing instructions, and launch and operating plans.

What does entering my email unlock?

Your email unlocks up to 25 free three-screen preview suites and lets Review Radar remember the allowance across visits. Research, source reviews, and idea generation remain available before that step. Purchasing is required only for a complete downloadable Blueprint folder.

Is finished source code included?

No. The Blueprint is the complete pre-code package for your AI coding tool. Open the folder in Codex, Claude Code, Cursor, or another capable coding agent, paste the included kickoff prompt, and the agent uses the files to build and verify the product with you.

When is a credit used?

Only when you choose an idea and request its downloadable Blueprint. Searching, reading reviews, comparing ideas, and regenerating ideas do not spend a credit. A failed Blueprint generation restores the reserved credit automatically.

Can I return later?

Yes. Purchased credits remain attached to your purchase email until you use them. Request a private sign-in link whenever you return to retrieve finished folders or use another credit.

Your first useful result is the research, not the checkout.
