Audit, launch, and rescue your app

AppGrout helps you ship AI-built/vibe-coded apps with confidence through human review, audits, and testing.

Choose your app stage

Finishing up

Your design and vibe-coded app are in place. Get engineering help with the remaining auth, payments, error handling, or deployment work, delivered as an agreed milestone.

Finish your next milestone

Pre-launch

You’re preparing to launch. Get a human review of key flows, access, and payments, with prioritized next steps so you know what to address before going live.

Prepare for launch

Post-launch

Your app is serving real users. Get focused fixes or feature improvements with regression checks for an agreed area, so you can spend more time on your users and business.

Plan your next improvement

Takeover

You’re ready to build your next app. Agree on the development scope and responsibilities, then let AppGrout carry the work forward while you focus on something new.

What we check and fix.

We inspect the agreed parts of your app: who can access data, how key flows behave, and what happens when something fails.

Does each user see only what they should?

Authentication, permissions, exposed secrets, and access between accounts.

Does the checkout work all the way through?

Login, payments, fulfillment, and the important journeys after the happy path.

Will it hold up when real people use it?

Slow pages, repeated queries, error handling, and practical recovery assumptions.

Can the fix be reviewed and verified?

Scoped repairs through a branch or pull request, with checks and a written handover.

How the work happens.

Choose the fixed package that fits your app, pay, then create the private workspace. An NDA is signed before private access is exchanged.

01Confirm the package fits

Review the published scope, exclusions, and production-data conditions for the $300 check, $1,000 audit, or $2,500 rescue sprint. Provide only a short, non-confidential summary before payment. If the package boundary does not fit, do not buy it.

02Pay, then create access

Pay with Wise, the preferred option, or use Stripe Checkout for a debit or credit card. After the payment is verified, sign in to create your portal workspace. This keeps unpaid enquiries out of the project database.

03Review or repair

Agree and sign the NDA before sharing private project materials. Use least-privilege access and staging or sanitized data where possible. Production work requires explicit authorization, a current backup, and a tested rollback path.

04Get a written handover

Receive findings, priorities, and next steps. A Full App Audit includes one limited retest for agreed findings.

Services & pricing.

Checks and audits identify problems. Rescue sprints cover implementation. Ongoing maintenance is scoped and quoted separately.

Launch Readiness Check

$300 / fixed scope

Find the most important blockers before your app meets real users.

Start a launch check View scope and boundaries
What you receive
  • One repository and one backend
  • One role and up to two critical user journeys
  • Selected auth, data access, secrets, and deployment checks
  • Launch blockers and prioritized next steps
  • Asynchronous by default

A focused readiness check, not a full application audit, penetration test, or implementation engagement.

App Rescue Sprint

$2,500 / fixed scope

Finish an incomplete feature, fix a production issue, or prepare a technical handover.

Start a rescue sprint View scope and boundaries
What the fixed sprint includes
  • One existing repository and one backend
  • One feature milestone or one tightly related defect cluster
  • Reviewable code changes with targeted regression checks
  • Acceptance criteria, verification notes, and handover
  • Up to one five-business-day engineering sprint

Fixed sprint boundary. The app must build or run, the desired outcome must be testable, and required access must be available. Rebuilds, migrations, emergency response, broad refactors, and unrelated fixes are excluded.

Fixed package prices in USD. Review each package boundary, prerequisites, taxes, transfer fees, cancellation terms, and production-data limits before payment.

App Overhaul

Rebuilds, migrations, and broader architecture changes need a separate scope. We review the app and agree on milestones, responsibilities, and pricing before work begins.

Frequently Asked Questions

Can you finish an app that is partly built?

Yes, when the work fits the published Rescue Sprint boundary: one repository and backend, and one feature milestone or tightly related defect cluster that can be tested within five business days. A rebuild, migration, or broad refactor needs a separate engagement, so do not buy the fixed sprint for that work.

Can you take over maintenance while I build something else?

We can scope a handover of an existing application and discuss ongoing maintenance. Code, deployment, access, and known issues need to be reviewed first. Responsibilities, response times, availability, and fees are agreed separately; ongoing maintenance and 24/7 incident response are not included in a rescue sprint.

Is this an automated scanner?

No. An engineer reviews the agreed code and user flows. Automated checks may support the work, but the findings and proposed changes are reviewed by a person.

Does the launch check include fixes?

The Launch Readiness Check provides focused findings and next steps for the agreed journeys. Repair work is agreed separately with a defined milestone and acceptance criteria.

Do I need a call before paying?

No. All three services have a published fixed scope and price. Share a short, non-confidential summary, confirm that your app fits the package boundary, accept the terms, and pay by Wise or Stripe. Your portal workspace is created only after payment is verified.

Can we work without a call?

Yes. The default is asynchronous. Payment books the selected service, not just a call. If a technical call is useful, its time is confirmed after payment is verified.

Is the $2,500 rescue a full overhaul?

No. $2,500 covers one defined remediation milestone or tightly related defect cluster within one five-business-day sprint. Broad refactors, migrations, rebuilds, emergency response, and unrelated fixes are outside this package.

Can we sign an NDA first?

Yes. We agree on and sign an NDA before private project materials are exchanged. You can propose your own agreement for review. Anyone approved to assist must also be bound by confidentiality obligations. Read our confidentiality approach ↗

How do you keep access limited?

Use least-privilege repository invitations and the agreed access process. Staging, sanitized evidence, and synthetic data are preferred. Production changes require explicit authorization, a current backup, and a tested rollback path. Never paste passwords, tokens, or private keys into a form.

What if my app needs a different scope?

Do not pay for a fixed package if your app exceeds its published boundary. Contact us first so we can decline it, reduce the milestone, or discuss a separate custom engagement without pretending the fixed package covers more than it does.

Let's get started

Choose a fixed package, confirm that your app fits its boundary, and pay before the private workspace is created.
