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.

Make this idea your next project.

Your Blueprint expands this selected idea and design direction into the full first-release screen suite, build prompts, backend instructions, and a publishing guide. Everything stays together in one folder for your AI coding tool.

You receive the designs and instructions, not a finished app. Your AI builds with you, one working feature at a time.

Difficult to setup

“It’s very difficult to set up this app on my phone. I tried six times to login without success.”

The problemThis reviewer could not sign in after repeated attempts, so never reached the app's main value.

A question to investigateCould clearer sign-in feedback and a reliable recovery path help this audience? More reviews and user testing must support that direction.

What you receive

Open one folder. Paste one prompt. Start building.

Not another blank chat. Your AI starts with your app's research, designs, technical decisions, and build instructions already in one place.

1. Open your folderUnzip it and open the whole project in Codex, Claude Code, Cursor, or another capable AI coding tool.

2. Paste the starting promptYour AI reads the files, explains the first build, and identifies any accounts or decisions that need you.

3. Build, test, then launchFollow the tailored prompts, one feature at a time. Check the result against your designs and prepare a beta for friends.

Inside the project folder

Designed for your app. Organized for your AI.

Complete screen systemDesigns for your first release, including the important empty, error, and success states.
A clear first versionWho it serves, what it does, the supporting reviews, and what to build next.
Behind-the-scenes instructionsHow accounts, saved data, permissions, and connected services should work.
Build prompts in orderWhat to ask your AI next, how to test its work, and how to resume later.
Beta and publishingAccount setup, friend testing, and the steps to submit to a store or publish on the web.
A launch and growth guidePositioning, marketing experiments, support, maintenance, and future releases.

The app decides the screen count. Your agreed first release is covered; bigger ambitions get a phased roadmap.

Your first session

YOUR-FIRST-SESSION.md gives you a short, app-specific introduction. START-HERE-PROMPT.md tells your AI to read the project, check what's needed, and explain the next step before writing code.

Explore this project folder. Read PROJECT-DIRECTORY-GUIDE.md and the roadmap. Inventory the screens, data model, build prompts, and tests. Explain the first working user journey and what you need from me before writing code.

A shortened illustration of the kickoff instruction. Your delivered prompt is tailored to your app and its files.

The files your AI reads

PROJECT-DIRECTORY-GUIDE.md: how the whole folder works.
BUILD-THIS-APP.md: your audience, first version, platform, and definition of done.
PROMPT-SEQUENCE.md: the build and launch prompts in order.
CURRENT-STATE.md: progress and the exact place to resume.

The designs and build instructions

screen-images/png/ contains the full-resolution design references. design/screens/ explains what every screen does. architecture/ describes data and services. visual-qa/ supplies checks to compare the running app with its designs.

From a working build to launch

BETA-AND-DEMO-PLAYBOOK.md guides early testing. turnkey/ contains the account, publishing, business, marketing, and support instructions. Your AI turns these into specific next actions for your app.

We prepare the Blueprint

Your app-specific research, designs, instructions, and checks in one downloadable folder. A failed Blueprint generation restores its credit. Re-downloading a finished folder uses no extra credit.

You build with your AI

You provide your coding tool, approve decisions, and set up your own accounts. AI usage, hosting, store fees, and other services are separate. Source code, store approval, customers, and revenue are not included or guaranteed.

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.

Why not just ask my AI to build an app?

You can. Review Radar adds the work that normally happens before that request: review evidence, a focused product brief, a coherent screen system, technical decisions, and a connected build-and-launch sequence. Your AI gets a shared set of references to work from, not just a description to interpret.

Can this cover a big idea, like a social network?

Yes, with an agreed first release. The folder covers its required journeys and screen states, and maps the larger vision into later phases. A complex app still needs implementation, testing, moderation, security, and ongoing work. We do not promise a one-shot build or a particular completion time.

Does review research prove people will buy?

No. Reviews reveal problems and preferences, not guaranteed demand. Your Blueprint includes assumptions to test and suggested validation steps. You can inspect the source reviews and decide whether the evidence supports the direction.

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.

Start with evidence

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

Describe the market you are curious about. Review Radar will show you what real customers repeatedly want before you decide whether any idea deserves a complete project folder.
