Catch avoidable App Store submission blockers before review.
A guided preflight for apps built with Expo and React Native. It checks your repository and your final iPhone build, then walks you through the App Store Connect and reviewer steps that local code cannot confirm — so avoidable problems surface before you send the build to Apple.
$99 USD planned founding price · one-time · checkout closed during the internal alpha
This is an expanded internal alpha. It runs today on real production apps — repository checks, final iOS build inspection, and a guided submission checklist — and Verto is dogfooding it before asking anyone to pay. Checkout stays closed until that dogfood passes. It never signs in to your App Store Connect account and it is not affiliated with Apple. Only after it catches useful issues without noisy false alarms will paid validation open.
01
For founders and small teams who built an iPhone app with Expo, Claude, Cursor, Codex, or a developer — and want to catch avoidable App Store problems before submitting it to Apple.
Run it before you submit
When delivered, open your app project and run one command before TestFlight or App Review. Point it at your final build too, so the checks run on what you actually shipped.
app-store-preflightSee what still needs work
It sorts every result into what it verified automatically, what you confirmed yourself, and what still needs confirmation — no false all-clear.
Fix, confirm, then submit
Every problem names the exact file or field, why it matters for App Review, and a concrete fix you can apply yourself or hand to Claude, Cursor, or Codex.
A Contacts permission is declared, but nothing in the project uses contacts.
app.json → NSContactsUsageDescription
Delete the key, or add the package that needs it. App Review flags unused permissions under Guideline 2.3.
02
Honest scope, both directions. The preflight is precise about what it can prove and plain about what it cannot.
It does
Checks your repository — app config, permission explanations, package compatibility, store metadata, and subscription wiring.
It does
Inspects your final iOS build (.app or .ipa) and reads the shipped Info.plist, so what you actually built is verified, not just what the repo says.
It does
Walks you through a guided external checklist for the App Store Connect and reviewer steps no local check can prove.
It does
Gives you a prioritized report: what is verified, what you confirmed, and what still needs confirmation.
It does
Helps you write reviewer notes and, after a rejection, draft a response mapped to the likely cause.
What it deliberately does not do
It does not
It never signs in to or reads your App Store Connect account. Repository wiring cannot prove what is attached to a version; the report says so instead of guessing.
It does not
It uses no network. It runs locally and nothing about your code leaves your machine.
It does not
It is not affiliated with Apple, and it does not predict what a reviewer will decide.
03
This is what a developer would receive. It is real output from the expanded internal alpha, run against a committed, deliberately imperfect Expo fixture. The decision is never a customer-facing ship/no-ship certainty — it is one of critical risks, unresolved checks, or no deterministic blockers — and every result is labelled as verified, confirmed, or still needing confirmation. Technical readers can inspect the sample files and trace every finding back to its source.
1 deterministic blocker must be resolved before submission.
Checks the tool proved from your project and build.
External steps you confirmed. Your word, kept separate from what the tool verified.
Nobody has confirmed these yet. The report will not guess.
iOS app identity
iOS permission explanations
Expo package compatibility
App Store listing metadata
Subscription submission wiring
iOS build artifact (final Info.plist)
Developer-confirmed submission checklist
Internal dogfood build. Repository findings are real; checks requiring App Store Connect are explicitly marked needs-input when no export is supplied.

The exact initial bundle, delivered as one downloadable package. Four things, bounded on purpose:
Compatibility bounds
05
Not a code generator
It reads your project and your build and reports. It does not scaffold apps, write features, or refactor your source.
Not a consulting retainer
No audits of your app, no submission-on-your-behalf, no calls. Support is best-effort email for bugs in the tool.
Not an Apple oracle
No guarantee of approval. Deterministic checks catch deterministic problems. Apple can still reject a build for design, content, or reviewer judgement no static check can see.

Checkout is closed while the alpha is dogfooded. That is the point of this page: paid validation opens only after the tool earns it on real apps.

Three source-backed write-ups on the App Store problems this preflight exists to catch. Each links to Apple's and the vendor's own documentation.

$99USD
Planned one-time global founding price. Not a subscription. Checkout is currently closed while the alpha is dogfooded on real production apps.
See what the preflight checks- 01
The preflight is an expanded internal alpha. Checkout stays closed until it has been dogfooded on real production apps.
We will publish what it checked, what it found, and what we had to change before any customer is asked to pay.
- 02
Validation passes at 3 paid preorders from unrelated buyers.
This paid-validation gate starts only after the alpha is dogfooded. Test purchases, duplicate buyers, and anyone involved in the product do not count.
- 03
If it passes, Verto delivers the first version within 30 days after validation closes.
Delivery is planned as a downloadable package plus a private repository invite.
- 04
If it fails, Verto refunds every preorder in full.
Refunds are not automatic. Verto issues them manually through Stripe to the card you paid with, and emails you when the refund is sent.
No payment can be made today. The future paid-validation terms are documented on the terms and refunds page.
