Expanded internal alphaExpo · React Native · iOS

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.

Where this is

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.

01

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.

02

See 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.

03

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.

Example blockerLeftover permission
Problem

A Contacts permission is declared, but nothing in the project uses contacts.

Found in

app.json → NSContactsUsageDescription

Fix

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.

CRITICAL-RISKS

1 deterministic blocker must be resolved before submission.

Nobody has confirmed these yet. The report will not guess.

The exact initial bundle, delivered as one downloadable package. Four things, bounded on purpose:

Repository + build preflightRun one command from your Expo or React Native project. The checker inspects your app configuration, package versions, permission explanations, store metadata, and subscription wiring, then reads the final iOS build's Info.plist so the checks run against what you actually shipped. It runs locally and sends nothing anywhere.
A prioritized report you can act onEvery item is classed as automatically verified, developer-confirmed, or needs confirmation. Problems carry a severity, the exact file and field, why it matters for App Review, and a concrete fix. The summary is honest: critical risks, unresolved checks, or no deterministic blockers — never a false ready-to-submit certainty.
A guided external checklistFor the App Store Connect and reviewer steps no repository can prove — live privacy links, a tested reviewer account, subscription attachment, in-app account deletion — the kit walks you through confirming each one, and keeps your answers separate from what the tool verified itself.
Reviewer notes and rejection helpDraft reviewer notes before you submit. If Apple rejects the build, paste the message: the kit maps it to the likely issue, suggests a fix plan, and drafts a response you can check and send. No guaranteed fixes — a starting point you review.

Compatibility bounds

PlatformiOS submissions only. Android is out of scope for the first version.
FrameworksExpo SDK 52, 53, and 54; React Native 0.76, 0.79, and 0.81; managed and prebuild workflows.
RuntimeNode 20 or newer. Runs on macOS and Linux.
Updates12 months of updates from delivery. Not lifetime. After 12 months it keeps working on the SDKs it shipped with; newer SDKs are not guaranteed.
SupportEmail, best-effort, bug reports only. This is not a consulting retainer and does not include audits of your app.
DeliveryA downloadable package plus a private repo invite. No hosted service, no account, no telemetry.

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.

Not for sale yet

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.

06

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.

Expo iOS permission (purpose) strings that pass App ReviewWhy iOS requires a purpose string for every permission, how to configure them in an Expo app, and the wording App Review rejects under Guideline 5.1.1.
RevenueCat wired, subscription still missing from the App Store versionWhy your repository can show RevenueCat is installed and configured yet still can't prove the product is attached to the version Apple reviews — and how to check.
Apple's in-app account deletion requirement for Expo appsIf your app creates accounts, Apple requires in-app account deletion. What a repository scan can hint at, and what you must test by hand before submitting.

After the alpha is dogfooded

$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
  1. 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.

  2. 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.

  3. 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.

  4. 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.
