Offers - App Rescue Audit

€1,500 excl. VAT · 5 business days · 100% remote

Your app project went off the rails: blown budget, unstable app, store rejections, an agency that no longer answers, or code generated by an AI tool that nobody understands anymore. Before putting more money into the project, get a rescue audit: we recover your access, read the code and tell you, with figures, whether to save the app, partly rebuild it or start over.

Who is it for?

This recovery audit is for you if:

  • •Your rebuild or migration went over budget and past its deadlines, without a stable result
  • •The app crashes, slows down or loses data, and every fix creates new bugs
  • •Apple or Google is rejecting your updates or has sent you a warning
  • •Your agency or freelancer has vanished or no longer answers
  • •Nobody dares to touch the code, and only one developer knew how to release the app
  • •Your app was generated with Lovable, Bolt or Cursor and now needs a real developer to move forward

What you get

On delivery, you receive:

  • •An access recovery checklist: code repository, App Store Connect and Google Play Console accounts, Android signing key, domain names, hosting and database, third-party API keys, contracts and the IP assignment clause. For each one: in your name or not, and what to ask for
  • •A code and architecture review: does the app build from the repository, is the code readable, tested and documented, where are the weak spots
  • •A quick security check: exposed secret keys, data access rules (Supabase, Firebase, APIs), admin accounts
  • •The state of dependencies and store compliance: framework versions, abandoned libraries, Apple’s and Google’s current requirements
  • •A clear verdict: save, partly rebuild or start over, with a costed and prioritized plan (steps, duration, risks, recommended order)
  • •A PDF report that a non-technical reader can follow, ready to share with your partners, management or another team
  • •A one-hour debrief call to answer all your questions

Three possible verdicts

After a failed rebuild, the temptation is to throw everything away. It is not always the right call: a rebuild has to recover every business rule of the old app, which are often undocumented. The audit decides on facts.

  • Save

    The code is recovered, it builds, and the foundation is sound despite localized flaws. You get a prioritized list of fixes, without questioning everything.

  • Partly rebuild

    One part holds up (server, data, business logic), another needs to be redone (mobile app, a fragile module). We tell you what to keep, what to redo and in which order.

  • Start over

    Code nowhere to be found, abandoned technology or a foundation too fragile. We tell you plainly, with an inventory of what the current app does so nothing gets lost along the way.

Technologies covered

The rescue audit is not tied to a single technology, but it stays within what we work with every day:

  • •React Native and Expo mobile apps
  • •Capacitor, Ionic and Cordova hybrid apps
  • •React, Next.js and Vue.js web apps, Node.js servers
  • •Code generated by Lovable or Bolt (React and Supabase), or written with Cursor

A fully native app (Swift, Kotlin) or a Flutter app is not our core expertise. If that is your case, we tell you on the qualification call, before you order anything, rather than sell you an audit others will do better. For a Bubble, Adalo or FlutterFlow app, see the Move off no-code offer instead.

Why an emergency audit before spending more

When a project has gone off the rails, the reflex is to ask for takeover quotes. The problem: without reading the code or checking the access, nobody can seriously price what comes next. This audit separates facts from impressions and gives you a common basis to compare proposals, ours as well as other teams’.

If you then hire us for the recommended work (for example Google Play and App Store compliance, an Expo upgrade, a migration to Capacitor or a takeover quoted separately), the audit is deducted from the final price if you confirm within 30 days. Nothing obliges you to hire us for what follows: the report can be used by any team.

Your React Native app works and only needs a version upgrade? The React Native Migration Audit is a better fit. To understand the first steps after a failed project, read our guide Failed app rebuild: what to do now?

How it works

  1. Step 1

    Qualification call (30 minutes, free)

    You tell us what happened. We check that your technology is within our scope and that the code is accessible before you order anything.

  2. Step 2

    Kick-off and access inventory

    Together we go over what is in your name and what is missing. From day one you know what to ask for, and from whom.

  3. Step 3

    Code and release review

    We rebuild the app from the repository, read the code, and check security, dependencies and compliance with Apple’s and Google’s rules.

  4. Step 4

    Report and debrief

    You receive the PDF report and we walk through it together for an hour: verdict, risks, costed and prioritized plan.

What the audit is not

  • •Not legal advice: we flag it if the IP assignment for the code is missing or unclear in your contracts, but only a lawyer can settle it
  • •Not a penetration test: the security check catches the most common and most serious flaws, not every possible one
  • •Not the fixes: the audit sets out the diagnosis and the plan; the work is priced separately, at a fixed price

What we need to get started

  • •Read access to the code repository (GitHub, GitLab, Bitbucket), or the Lovable or Bolt project connected to GitHub
  • •Whatever access you already have: App Store Connect, Google Play Console, hosting, database (we show you how to invite us without sharing your passwords)
  • •Your contracts, quotes and specifications if you have them
  • •Someone available for 1 hour at kick-off and 1 hour for the debrief

Frequently asked questions

What is an app rescue audit?
GUIGUI Tech’s App Rescue Audit is a recovery audit, or emergency audit, for an app whose project went off the rails: a failed rebuild, a blown budget, an unstable app, an unreachable developer or code generated with Lovable, Bolt or Cursor. It checks your access, the code, security, dependencies and store compliance, then recommends saving, partly rebuilding or rebuilding the app, with a costed plan.
How much does an app rescue audit cost?
GUIGUI Tech’s App Rescue Audit costs €1,500 excl. VAT, fixed price, delivered in 5 business days. It includes the access recovery checklist, a review of the code and architecture, a quick security check, the state of dependencies and App Store and Google Play compliance, a costed and prioritized verdict, a PDF report and a one-hour debrief call.
Which technologies does the app rescue audit cover?
GUIGUI Tech’s App Rescue Audit covers React Native and Expo apps, Capacitor, Ionic and Cordova apps, React, Next.js and Vue.js web apps, Node.js servers and code generated by Lovable or Bolt (React and Supabase). For a fully native app (Swift, Kotlin) or a Flutter app, this is not our core expertise: we tell you so on the first call, before you order anything.
My developer no longer answers: can you still take over the app?
Yes, in most cases. GUIGUI Tech’s App Rescue Audit starts with an inventory of what is in your name and what is missing: code repository, App Store Connect and Google Play Console accounts, Android signing key, domains, hosting, API keys, contracts. You need at least access to the source code; the free qualification call is there to check this before the audit starts.
How is it different from the React Native migration audit?
GUIGUI Tech’s React Native Migration Audit is for a React Native app that works but needs a version upgrade. The App Rescue Audit is for a project that went off the rails, on any of the technologies we master: it starts with access and ends with a choice between saving, partly rebuilding or rebuilding. Both cost €1,500 excl. VAT for 5 business days.
What happens after the app rescue audit?
Depending on the verdict, next steps can be store compliance (from €2,500 excl. VAT), an Expo and New Architecture upgrade (from €6,500 excl. VAT), a Cordova or Ionic to Capacitor migration (from €9,500 excl. VAT), a full React Native migration (from €18,000 excl. VAT) or a takeover quoted separately. The €1,500 excl. VAT audit is deducted if you confirm within 30 days. The report can be used by any other team.
Does GUIGUI Tech sign an NDA before accessing the code?
Yes. A standard NDA is signed before any access to your app’s code and accounts as part of the App Rescue Audit.
