Reviewed by an engineer from Google, Apple & Meta

A senior engineer signs off your AI-built app. No hackers in. No surprise bill.

Built with Lovable, Bolt, Base44, Replit or Cursor? Connect your app. We review its architecture and code quality, lock every endpoint against bots and AI hackers, cap everything that costs you money, and keep checking after you launch.

Simulation

Watch an attack hit your app.

Red dots are bots, scanners and AI agents hunting for an open endpoint. Green dots are your real users. Switch the protection on and see what changes.

  • Every endpoint asks who is callingNo sign-in, no answer. Nothing is left open by accident.
  • Limits per user, device and addressOne caller can't run your paid feature a thousand times.
  • Your admin dashboard stays yoursNobody reaches it by guessing the address or changing a setting in their browser.
  • AI hackers slowed, then shut outAutomated agents that probe for holes all day get nothing useful back.
  • Your AI feature can't be talked into itInstructions hidden in a user's message don't override yours.

Illustration only. The numbers are simulated, not a measurement of any real app.

Why AI-built apps break after launch

AI is only as good as the person telling it what to do.

It builds exactly what you ask for. If you don't know to ask for locked endpoints, limits per user or a spending cap, you don't get them.

We're the person who knows what to ask, after years as an engineer at Google, Apple, Meta, Amazon and Netflix. For hire.

01 · THE APP

Stuck before the store

Signing certificates, tester builds, screenshots in six sizes, privacy forms, then a rejection written in reviewer language.

Most AI builders stop at a web link or hand you over to developer tools.

02 · THE HACK

An open door for hackers

The app looks fine, but its database answers anyone who asks, or one of its packages has a known hole. You can see a broken button. You can't see this.

Typical causes: open database rules, secret keys inside the app, out-of-date packages.

03 · THE BILL

A bill you didn't plan for

One person, or one script, calls your AI feature thousands of times overnight. Usage pricing charges you for all of it.

Typical causes: no limit per user, no spending cap, keys that can be copied.

Don't take our word for it

Ask the AI that built your app.

Start with these six. Paste them into your builder, word for word. They are among the first things a senior engineer at a big-tech company asks before a launch, and most people are surprised by what comes back.

These are six of the many questions we recommend you ask. There are thousands more, from design to safety to the bill to production.

  • DesignWhere does this business rule live?
  • SafetyWho is allowed to delete a user?
  • BillWhat does one active user cost me a month?
  • ProductionHow do I roll back a bad release?
  • DesignWhat happens when two people edit the same record?
  • SafetyWhat does the error page tell an attacker?
  • BillWhich call retries forever?
  • ProductionHas a restore from backup ever been tried?
  • ProductionWho finds out when the app is down?
  • BillWhich request has no timeout?
  • SafetyAre uploads checked before they're stored?
  • DesignWhich screen breaks with no internet?
  • ProductionWhat is logged when a payment fails?
  • BillWhat happens when a free user finds the paid feature?
  • SafetyCan a signed-out user reach the admin page?
  • DesignCan I export one user's data if they ask?
It says everything is fine?

That's the author marking its own homework. An AI will tell you what it believes it built, not what is running. Somebody has to open the code and check.

It hedged, apologised, or started rewriting things?

Then it didn't know, because nobody asked it to build those parts. Every change it makes now can break something else. Stop there and let an engineer look first.

Send us what it said. We'll check its answers for free.

You'll hear back which answers hold up and which one would hurt you first. No payment, no call, no obligation.

How we compare

Everything a scanner catches. Plus what it can't.

Automated scanners are good at finding known holes, and we run those checks too. The last four rows need judgment, and that takes a person.

How it works

You connect it. We do the rest.

  1. Connect your app

    Link the app from your builder, or its code. Add one line on what it does and who it's for.

    You: about 5 minutesYou geta reply from an engineer within two working days

  2. We review how it's built

    We read the architecture and the code: how the data is modelled, what runs on the server, and whether the code can keep being changed without breaking.

    You geta plain-English verdict on how your app is put together

  3. We run the checks

    Every item on the list below, including an attack on your paid features to see what it would cost. You get the report and we fix what we find, or tell you exactly what to change in your builder.

    You getresults from 2,000+ checks, and the dollar cost of an attack on your app. This is the $50 check.

  4. We submit it

    iPhone and Android builds, a tester version for your own phone, the store listing, privacy answers and the submission itself, under your own developer accounts. If a store rejects it, we answer the reviewer and resubmit.

    You getyour app in both stores, under your own name

  5. We keep guard

    Optional. Every day we re-check the packages your app is built on for newly found security holes, and every week we re-run the bill, endpoint and hacking checks. When something turns up, you get an email with the fix written so you can paste it into your builder.

    You getan email only when something needs fixing, with the fix

Nothing hidden: the full list

2,000+ checks your AI builder never ran.

Below are the 27 that hurt most when they're missed. You get every line back with a result, and a fix for each one that fails.

Architecture and code quality

  • The data model fits the app, with nothing duplicated or left orphaned
  • Business rules run on the server, not inside the app
  • Code is organised so your AI builder can keep changing it safely
  • Errors are handled and reported, not silently swallowed
  • It holds up as users grow: no slow queries or endless lists
  • The paths that take money or touch data have tests

Store rules

  • The app is a real app, not only a website in a frame
  • No code is downloaded and run after review
  • Sign-in, account deletion and purchases follow each store's rules
  • Privacy answers match what the app collects
  • Screenshots and description show what the app does

Hackers and your users' data

  • One user cannot read or change another user's records
  • No secret keys or passwords inside the app
  • Login and password reset limit repeated attempts
  • Admin and payment actions are decided on the server
  • Text typed by users can't be run as a database command
  • No package the app depends on has a known security hole

Your bill

  • Every paid feature has a limit per user and per device
  • AI and hosting accounts have a spending cap and an alert
  • Keys for paid services can't be copied out of the app
  • No loop that calls a paid service without end
  • A measured attack, with what it would have cost you

Endpoints and AI attackers

  • Every endpoint checks who is calling before it answers
  • Your admin dashboard opens only for you: not signed-out visitors, not ordinary users
  • Bots, scanners and AI agents are slowed, then blocked
  • AI features ignore instructions hidden in user text
  • Error messages give an attacker nothing to work with

What you walk away with

Four things you don't have today.

01The truth about your app

A written report covering 2,000+ checks, in plain English. No score to interpret.

02A number for your worst night

What an attack on your paid features would cost you, measured before and after the fix.

03Fixes you can apply yourself

Each one written as an instruction to paste into your builder. No developer to hire.

04A big-tech engineer on your side

Someone who has read your code and answers when you ask "is this safe to ship?"

Pricing

Start at $50 per app.

Straight answers

What we don't promise.

We can't guarantee approval.

Apple and Google decide. We check against their published rules and handle rejections, and we tell you before you pay if the app is unlikely to pass.

We can't promise an app will never be hacked.

Nobody honestly can. We close the common holes on a fixed list, show you the result of each check, and keep checking after launch.

The app stays yours.

It is published under your own Apple and Google accounts, in your name. We never hold your listing.

What "no surprise bill" covers.

Limits on every paid feature and a spending cap on each account you give us access to, tested by attacking them. It can't cover an account we never saw or a change made after our last check.

We don't need your users' data.

Checks run with test accounts. For the cost test we agree a ceiling with you first, usually a few dollars.

A person does the review.

The review is done by hand, by an engineer, not by a bot. Expect days, not minutes, and direct replies from the person doing it.

Questions

Before you ask.

My app is a web app. Can it go in the stores?

Often, yes, but Apple rejects apps that are only a website in a frame. We look at the project first and tell you what it would need. If it isn't a fit, you pay nothing.

Do I need my own developer accounts?

Yes. Apple and Google expect an app to be published by its owner. We walk you through opening both accounts and you invite us with limited access, which you can remove at any time.

What access do you need to my project?

Read access to the code, and limited access to the accounts being checked. We don't need your users' data. For the cost test we use test accounts and agree a ceiling with you first.

What if you find a problem you can't fix?

You still get the report, with the exact change to ask your builder for. If the app can't be made ready, we say so before submitting.

How long does it take?

Plan on one to two weeks from connecting your app to submission. Store review time on top of that is up to Apple and Google.
