App Rescue Sprint

Fix or finish your vibe-coded app with a defined milestone.

When each AI-generated fix creates another problem, the useful next step is not another vague prompt. AppGrout scopes one outcome, makes reviewable engineering changes, checks them against agreed acceptance criteria, and hands the work back with context.

Good rescue-sprint candidates

Work that can be turned into one clear milestone.

The sprint starts with a testable result and a runnable baseline. Work outside one feature milestone or tightly related defect cluster is not part of this package.

Finish an incomplete feature

Complete an agreed journey that is partly implemented, with the missing states and acceptance criteria made explicit.

Repair a production problem

Investigate and address a defined issue in an affected flow, then run the agreed regression checks before handover.

Prepare a technical handover

Stabilize an agreed area and document the relevant code, deployment, access, and known issues for the next engineer.

How the sprint works

Confirm the package fit. Then make the change.

The published boundary is the control point: one existing repository and backend, one milestone or related defect cluster, testable acceptance criteria, and one five-day engineering sprint.

Read the confidentiality approach ↗

01
Describe the stuck point
Start with a non-confidential overview: what works, what is broken or unfinished, and what outcome you need.
02
Confirm prerequisites
Complete the NDA and provide the runnable baseline, acceptance criteria, safe test environment, access, and any required backup or rollback path.
03
Implement reviewable changes
Changes follow the agreed repository workflow so you can inspect what changed and connect it to the accepted milestone.
04
Verify and hand over
We check the agreed criteria and provide handover context, including relevant known limits or follow-up work.

Choose the right starting point

Do you need diagnosis or implementation?

Choose a rescue sprint when

The outcome is clear enough to scope.

You know the feature or affected flow.
You can describe what “done” should look like.
You want AppGrout to implement an agreed change.

Start rescue checkout ↗

Choose an audit when

You need evidence before deciding what to fix.

You are uncertain where the main risk sits.
You want findings prioritized across critical journeys.
You need a remediation plan before implementation.

Clear boundaries

A sprint is not an open-ended rebuild.

Software work carries uncertainty. The sprint controls it by defining a milestone and recording what is outside the engagement; it does not promise a flawless app or unlimited changes.

Unlimited changes, a full overhaul, or a promise to fix everything
24/7 incident response
Rebuilds, platform migrations, or broad architecture replacement
Unapproved production changes, bulk data edits, or work without a rollback path
Ongoing maintenance unless it is quoted and agreed separately

App Rescue Sprint questions.

Can you finish an app that is only partly built?

Yes, when the remaining work can be defined as an agreed milestone. We first review the current state, the desired outcome, dependencies, and acceptance criteria. Larger or uncertain rebuilds need a separate application-overhaul scope.

Does the fixed price cover the whole app?

No. The fixed $2,500 package covers one feature milestone or one tightly related defect cluster that fits within one five-business-day engineering sprint. It is not unlimited development or a promise to fix every issue.

Can you repair a production issue?

Yes, when the affected flow and acceptance criteria are clear, the app has a reproducible baseline, and a safe test path exists. Production changes require explicit authorization, a current backup or rollback path, and no uncontrolled bulk edits to live customer data. The sprint does not include 24/7 incident response.

Will I be able to review the code changes?

The service is designed around reviewable code changes, acceptance criteria, targeted regression checks, verification notes, and a handover through the agreed repository workflow.

Do we need to start with an audit?

Not always. If the problem and desired milestone fit the published sprint boundary, you can check out directly. If the cause or broader risk is uncertain, use a Launch Readiness Check or Full App Audit first.

Can you take over ongoing maintenance afterward?

Ongoing maintenance can be discussed after the code, deployment, access, known issues, responsibilities, and response expectations are reviewed. It is quoted separately and is not included in a rescue sprint.
