React Native Code Audit Services
We uncover what slows your app down, puts user data at risk, and makes each
update harder, on iOS and Android at the same time. You receive a scored report
with color-coded findings, a fix roadmap ranked by business impact, and answers to
every question you have about your code.
When Your React Native
Application Needs a Code Audit
Your React Native app serves iOS and Android customers from one codebase, so a single problem in the code reaches
both audiences. A code audit gives you a clear list of those problems and the order to fix them in.
Keep the App Fast and Stable
Users delete apps that freeze or crash, and leave reviews that deter new downloads. We pinpoint the causes and rank fixes by their effect on your customers.
Lower Maintenance Costs
Your developers need more time to change code that’s hard to read, and you pay for every extra hour. Our audit shows where cleanup saves your team the most effort.
Reduce Cyber Risk
Attackers can use a single security gap to reach your customers’ data and damage your brand. We locate these gaps and explain how to close each one.
Meet Compliance Requirements
Apple and Google reject updates that break their privacy rules, and regulators fine companies that mishandle personal data. Our engineers check your app against both before your next release.
Use Infrastructure More Efficiently
You pay for every request your app sends to your servers, including the unnecessary ones. We find the excess and show how to cut it.
Make Future Development Easier
New features take longer when developers must work around outdated code and libraries. You get an upgrade path so your team can release at the pace your business needs.
Our React Native Code Audit Services
Request a full audit of your React Native app, or focus on the area that worries you most, such as slow screens or security gaps.
You can also combine several services into one engagement and receive a single report.
Comprehensive Code Audit
This option is for when you need the whole picture: you’re buying a product, taking over code from another vendor, or preparing a big release and want to know what you’re working with.
Beyond a React Native code review, this audit also involves running the app on iPhones and Android phones to see how it behaves. We cover architecture, security and performance, plus the things teams tend to forget about, like test coverage, documentation, and commit history.
Code Maintainability Audit
Does each upgrade take ages because developers have to work around crutches left by previous teams, guess what a function does from its name, and copy the same logic into yet another file?
We check how readable and consistent the code is, where logic is duplicated, and how far one change spreads through the app. Then we tell you where to start cleaning up, usually with the modules your team edits every week.
Application Architecture Audit
When adding a small feature means editing a dozen files in different parts of the app, the problem lies deeper than individual lines of code.
We look at how the app is split into parts, how those parts exchange data, and how the shared code connects with the iOS- and Android-specific pieces. You’ll get recommendations for a structure that’s easier to extend and easier for new developers to learn.
Performance and Memory Usage Audit
You lose users over slow screens and crashes, and owners of older Android phones usually notice them first.
We test the app on physical devices, including cheap ones, and trace every slowdown back to the code behind it. Sometimes it’s a memory leak, sometimes a list that tries to render a thousand items at once.
Secure Code Audit
Anyone who installs your React Native app can open its JavaScript bundle and read the code, including any API keys someone left there.
We start with a multi-agent AI review, and then our engineers go through the results and the code by hand. Besides exposed keys, we check how the app stores tokens, how login works, which npm packages are outdated, and whether the app follows Apple and Google privacy rules.
What You Receive After the Audit
The exact set of documents depends on what the audit focused on. A security audit, for example, will have a different report than a performance one. But whatever the focus, you’ll get answers to every question you have about your code.
A Score-Based Audit Checklist
Each area we reviewed gets a score, from security to how easy the code is to maintain. It all fits on one page, which is handy when you need to show the results to stakeholders.
RAG (Red–Amber–Green) Rating System
Every finding is marked red, amber, or green. Red ones need attention right away, while green ones you can leave as they are.
Architecture & Dependency Diagrams
We draw how your app is put together and which external libraries it depends on, and we mark the places where those dependencies create risk.
Test Coverage Reports
You’ll see which features your automated tests protect and where bugs could slip through to users unnoticed.
Recommendations & Roadmap
Here we list the fixes in the order we’d tackle them, considering business impact and effort. Each one comes with a time estimate, so it’s easier to plan budgets and sprints around them.

Your React Native App
An outside team that has no stake in the code you already have can tell you
plainly where your app stands. Share your goals, and our engineers will suggest
the audit scope that fits them.
React Native Code Audit vs. Code Review
Both services check code quality, but they differ in what they cover and when you use them.
| Code Audit | Code Review* | |
|---|---|---|
| Scope | The entire codebase, from architecture to third-party dependencies | Specific changes, such as a pull request or a single feature |
| Timing | Once, or at key milestones like a version upgrade or an acquisition | Can be ongoing, as part of your development cycle |
| Result | A scored report with a prioritized roadmap | Can be comments and fix suggestions |
| Best for | Decisions about the app’s future | Keeping code quality consistent between releases |
*The table compares a typical audit with a typical review, though the lines can blur: an audit can focus on one area, such as security, and a review can cover an entire project in a single pass.
React Native Code Evaluation for
Different Project Scenarios
A fresh MVP and a five-year-old app in production call for different audits,
so we set the scope around where your project stands today.
Improving an Existing App
Your app is live, yet users report slow screens, or each release takes longer than the last. We find the causes and rank fixes by business value.
React Native Version Upgrade
Each skipped React Native release makes the next upgrade bigger. We estimate the effort and show which parts of your code need rework first.
Rescue of a Troubled Project
You need an outside view when deadlines keep slipping or a previous vendor has left. We recommend a refactor or a rebuild, plus a plan to recover your schedule.
Scaling an MVP
You built your MVP for speed. We show which parts of its code can support more users and features, and which to rework before you invest in growth.
Technical Due Diligence
Investors and buyers need to see what they’re paying for. We assess the app’s code risks and what it will cost to fix them.

The Cost To Audit Your React Native Code
The price of a React Native code check depends on how big your app is, what you want checked, and how deep the review goes. Below are cost ranges for our most common auditing requests:
| Code audit option | What it includes | Time | Cost |
|---|---|---|---|
| Automated audit | Uses automated tools to review React Native source code, coding standards adherence, build artifacts, dependencies, native modules, and architecture | Scoped to your app’s complexity, target platforms, and goals | $1,000–$5,000 |
| Static audit | Reviews source code, coding standards adherence, build artifacts, third-party libraries, CI/CD pipelines, release workflows, architecture, state management, and documentation | Scoped to your app’s complexity, target platforms, and goals | $5,000–$8,000 |
| Dynamic audit | Tests React Native app behavior on iOS and Android, including performance, rendering, and memory use under different usage scenarios and loads, as well as security controls | Depends on the app size, team, and static audit results | $8,000–$13,000 |
| Implementation | Refactors the codebase based on the audit reports, eliminates the root cause of issues, and optimizes the app according to set standards | Custom | Custom rate |
| Full audit package | Combines static and dynamic audits with the implementation stage | Custom | Custom rate |

React Native Code Audit FAQs
A small app usually takes a few days, and a large one can take up to three weeks. Some apps carry surprises that stretch the schedule: a dozen patch-package fixes inside node_modules, say, or a CodePush integration that has to move off Microsoft App Center after its 2025 shutdown. We’ll give you an exact timeline after the first interview.
The price comes down to how much there is to read and how deep you want us to dig. It starts at as little as $1000 (an automated scan of a basic solution with a small codebase).
Read-only access to the repository is enough to start. For the runtime part, we’d also like iOS and Android test builds and, if you have them, your Sentry or Crashlytics dashboards, since the source maps there often point straight at the screen causing trouble. A mutual NDA comes first.
Yes. We read the Swift, Objective-C, Kotlin, and Java code in your native modules alongside the JavaScript or TypeScript. The joint between the two layers gets extra attention: an old bridge module that sends a whole photo as a base64 string, for example, can freeze a scrolling gallery on mid-range phones.
Your team can keep shipping features while we work from read-only access. Plan for a short interview at the start and a call at the end to go through the findings.
Yes. DevCom is more than just a company providing code review for React Native apps. We can fix the issues ourselves, lend engineers to your team for the cleanup, or advise your developers while they work through the roadmap. Some fixes take an afternoon, like moving auth tokens from AsyncStorage to the iOS Keychain and Android Keystore. Others, like migrating a custom map module to the new architecture, take a sprint or two.
