Mobile App Code Audit Service — Find What's Broken | Appverra
+
Code Audit Service

Your App Has Problems.
We Find Them in 5 Days.

Appverra is a mobile app development company that has shipped 150+ apps for 700+ customers. Our apps have millions of downloads collectively. We audit iOS and Android codebases — Flutter, React Native, Swift, SwiftUI, Kotlin, Jetpack Compose — and deliver a severity-ranked report in 5 business days. Fixed price $2,997. No hourly billing. No ambiguity. You get a document that tells you exactly what is wrong, how bad it is, and what it costs to fix.

Signs You Need
a Code Audit

You do not need a code audit because you are paranoid. You need one because something is already broken and you cannot tell whether the fix is $5,000 or $50,000. These are the situations where founders call us.

You Inherited Code

You acquired a company, hired a new CTO, or took over a project from another agency. The code runs but nobody understands it. You need an independent assessment before committing budget.

Bugs Are Multiplying

Every fix introduces two new issues. Crash rates are climbing. Your developer says "it is just technical debt" but cannot explain why features that worked last month do not work today.

You Fired Your Dev Team

The relationship ended. You have source code in a repo you cannot evaluate yourself. Before hiring the next team, you need to know whether this code is fixable or needs to be rebuilt from scratch.

Performance Is Degrading

The app is slow. Users are complaining. App Store reviews mention lag, crashes, or battery drain. Your current team says they need "more time" but cannot quantify what is wrong.

Pre-Investment Due Diligence

An investor or acquirer asked for a technical assessment. You need an independent third-party code review that documents architecture quality, security posture, and scalability ceiling.

Vendor Lock-In Concern

Your app was built with proprietary tools, uncommon frameworks, or patterns that make it expensive to hire for. You want to know: can we migrate, or are we trapped?

What You
Get Back

A 15-30 page document written for a non-technical founder — not a dump of linting errors. Every finding is severity-ranked and paired with a cost estimate.

1. Architecture Assessment

How is the app structured? Is the architecture scalable? Are there patterns that will break at 10x or 100x users? We grade the overall architecture A through F with specific reasoning.

2. Severity-Ranked Issue List

Every bug, security flaw, performance bottleneck, and code smell — ranked Critical / High / Medium / Low. Critical means "this can take down your app or leak data." Low means "fix when convenient."

3. Security and Data Review

API key exposure, insecure storage, unencrypted transmission, authentication flaws, injection vulnerabilities. We check OWASP Mobile Top 10 and document every finding with reproduction steps.

4. Fix-or-Rebuild Verdict

The question every founder asks: "Can this be saved, or do we start over?" We give a direct answer with cost estimates for both paths. Fix this module ($X), rewrite that one ($Y), total rescue estimate ($Z).

5. Performance Benchmarks

Startup time, frame rate, memory usage, API response times, battery impact. We measure against platform standards (60fps, sub-2s cold start) and flag every metric that fails.

6. Prioritized Roadmap

A sequenced list: fix these 3 critical items first ($X, 2 weeks), then these 5 high items ($Y, 4 weeks), then these medium items ($Z, ongoing). You walk away knowing exactly what to spend and when.

Our Audit
Process

1

Intake

You share repo access (GitHub/GitLab/Bitbucket). We sign an NDA. You tell us what hurts most. 30-minute kickoff call with a co-founder.

2

Deep Dive

3-4 days of hands-on code review. We build the app locally, run it, trace critical paths, profile performance, scan for security flaws.

3

Report

We write the full audit document. Plain language. Severity rankings. Fix estimates. Architecture grade. Fix-or-rebuild verdict.

4

Walkthrough

60-minute video call where we walk you through every finding. You ask questions. We prioritize together. You decide next steps.

Audit
Pricing

Fixed-bid. You know the cost before you commit. No surprise invoices.

Honest Answers

How long does the audit take?

5 business days from the moment we receive repo access. Larger codebases (100K+ lines) may take 7-10 days — we will tell you on the intake call before you pay.

Do you need access to our production environment?

No. We work from source code only. We build the app locally, run it against staging or mock data. We do not touch production databases, servers, or user data.

What if the verdict is "rebuild from scratch"?

Then the audit just saved you months of patching a sinking ship. You have a clear document to show investors, co-founders, or your board explaining why the rebuild is necessary. If you want us to do the rebuild, the $2,997 audit fee is credited toward the Full Rescue tier.

Can I use the audit report to hire a different team?

Yes. The report is yours. Use it to brief your next agency, your in-house hire, or your CTO. We write it to be actionable for any competent engineering team — not just us.

What if my app was built with a no-code tool?

We audit exported or generated code from FlutterFlow, Bubble (exported), Adalo, and similar tools. If the platform does not export source code, we can do a functional audit (UX, performance, API) instead of a code-level review. Same price, different deliverable format.

Is there a refund if you find nothing wrong?

We have never delivered an audit that found nothing. Every codebase has issues. But if we somehow cannot deliver meaningful findings, we refund the full $2,997. That has not happened yet.
