Your AI-built app,
ready for real users.

You built it with Lovable, Bolt, Cursor or Claude Code. We make it secure and stable, then get it into the App Store and Play Store. It starts with a 3-day audit and a fixed price.

Native iOS and Android for 15+ years, 300+ projects. Senior engineers. You own the code, the accounts and the store listings.

The demo works. Launch is a different job.

AI tools are very good at getting you to a working prototype. Real users, real payments and app store review ask for things a prototype never had to think about.

What we usually see when we open an AI-built app

  • One user can see another user’s data.

    Change a number in the URL or the request, and someone else’s orders appear. This is the most common problem, and the easiest to miss.

  • Keys sit in the browser.

    If a secret key ships in the frontend, assume someone already has it.

  • Payments half work.

    Stripe takes the money, but nothing checks that the webhook really came from Stripe, so orders and access drift apart.

  • The platform holds everything.

    Your database, domain and deploys live inside the builder’s account. Moving out feels risky, so nobody does it.

  • Apple says no.

    A wrapped website gets rejected under guideline 4.2. Then 5.1.1 for account deletion. Then 2.5.1. Each round takes days.

  • Every fix breaks something else.

    After a few hundred prompts, nobody knows why the code works, including the AI.

None of this means you built it wrong. It means the next part needs an engineer.

Ship It: prototype to production, and into the stores.

One clear path, in three parts. You only commit to the next part once you have seen the last one.

  1. Part 1

    Audit

    $490. Credited in full if you go ahead with the sprint.

    3 working days

    A senior engineer goes through your app the way an attacker and an App Store reviewer would. You get a written report, a call to walk through it, and a fixed price for the sprint. Or an honest note that a rebuild makes more sense.

  2. Part 2

    Fix and ship sprint

    From $3,900, fixed after the audit.

    2 to 3 weeks, plus store review

    We fix what the audit found, move your app onto accounts you own, build the iOS and Android apps, and submit them to both stores. 30 days of support after launch is included.

  3. Part 3

    Care plan

    From $750 a month. Optional. Cancel any month.

    Monthly

    Updates for new iOS and Android versions, security patches, monitoring, and a set number of hours each month for small changes.

    See the care plan
  1. Step 1 of 4, 3 days

    Audit

    You give us read-only access. We test security, data, payments, hosting and store readiness, then send a written report and a fixed quote.

  2. Step 2 of 4, 2 to 3 weeks

    Sprint

    We fix the issues in priority order, set up staging, backups and error alerts, and build the iOS and Android apps. You get test builds every few days.

  3. Step 3 of 4, about 1 to 2 weeks

    Store

    We prepare the listings, privacy answers and review notes, then submit. If Apple or Google push back on anything in our scope, we fix it and resubmit.

  4. Step 4 of 4, monthly, optional

    Care

    We keep the app current with new OS versions, watch errors, and handle small changes. Or we hand everything over cleanly.

New Google Play personal accounts need 12 testers opted in for 14 days before an app can go public. We plan for this from day one so it runs alongside the sprint, not after it.

Built with any of these? We can take it from here.

Lovable, Bolt, Cursor, Claude Code, Replit, v0, and plain React, Next.js, Expo or Supabase projects. If it runs, we can read it.

No mobile app needed? The same audit covers a web app. For a web app, the sprint covers sign-in, payments, hosting, speed and security instead of store submission, and the fixed price comes with the audit report. Book an audit for a web app.

Why founders bring their apps to us

  • Native iOS and Android for 15+ years

    Most teams that fix AI-built apps stop at the web. We started as a native mobile team. Swift, Kotlin, signing, provisioning, TestFlight and Play Console are everyday work for us.

  • We build tools for this workflow

    We build BetaDrop, a free beta distribution tool for iOS and Android builds. It works inside Claude Code and Cursor through its MCP server. We know the path from a build on your laptop to an app on a tester’s phone because we built a product around it.

  • Security tested as the wrong user

    We don’t only run a scanner. We log in as one user and try to read another user’s data. We check every key, every webhook and every policy on your database, then fix what we find.

  • Senior people, small team

    The engineers on your calls are the engineers doing the work.

  • Work happens while you sleep

    We are in Ahmedabad, India. For US founders that means you send feedback at the end of your day and wake up to progress. We keep a daily overlap for calls.

  • You own everything

    The code, the hosting, the database, the Apple and Google accounts and the store listings are in your name. We work inside your accounts, not ours.

Sometimes the honest answeris a rebuild.

If the data model can't support what you need, or every change breaks two other things, patching it costs more than starting again. When that happens we say so in the audit, and we can build version one properly: native where it matters, scoped tightly, with a fixed price. The audit fee still counts towards it.

A one-page check for founders. Scope, security, store readiness and choosing who builds it. If more than three answers are "not sure", it is worth sorting those out before you spend more.

Questions founders ask

Why can't I keep asking the AI to fix it?

For small changes, you can. The trouble starts with problems the AI can't see from inside one prompt: a database policy that lets the wrong user in, a key that was exposed weeks ago, a payment flow that only fails under real load. These need someone to test the whole app from the outside, the way an attacker or a reviewer would.

Will you throw away what I built?

No. We keep what works and fix what is risky. Most apps need a focused sprint, not a rewrite. If a rebuild really is cheaper, the audit will say so and explain why, and the choice stays yours.

Some people offer free audits. Why is yours paid?

A free audit is usually a sales call. Ours is three days of a senior engineer's time and a written report you keep, whether you work with us or not. If you go ahead with the sprint, the audit fee is credited in full.

You are in India. How does that work with US time zones?

Well, mostly. We work while you sleep, so feedback you send in the evening is usually picked up by morning. We keep a daily overlap for calls, and you get a short written update on each working day of the sprint.

Can you guarantee Apple will approve the app?

No one can guarantee that, and you should be careful of anyone who does. What we do: prepare the app against the guidelines Apple most often uses to reject AI-built apps, write clear review notes, and if the rejection is about anything in our scope, fix it and resubmit without extra cost.

Who owns the code and the accounts?

You do. The code, hosting, database, domain, Apple developer account, Google Play account and store listings are all in your name. If you leave us, nothing needs to be moved.

Is my code safe with you?

We start with read-only access and only ask for more when the sprint needs it. We are happy to sign your NDA before the audit. Keys we touch during the sprint are rotated before handover.

What does it cost in total?

The audit is $490. Sprints start from $3,900 and the audit gives you a fixed figure before any build work starts. The care plan is optional, from $750 a month. You will also need your own Apple developer account (US$99 a year) and Google Play account (US$25 one time).

My app is a web app (for example a SaaS). Do I need the App Store part?

No. The same audit covers a web app with no app store involved. For a web app, the sprint covers sign-in, payments, hosting, speed and security instead of store submission. You get a fixed price for it with the audit report.
