Mobile app code audit
Anything in your app ends up on every device that installs it, and the app stores keep raising the bar. We review your React Native, Expo, Flutter, Swift, or Kotlin code against the problems mobile apps actually have, and tell you in plain English which ones matter and what to fix first.
Every mobile audit covers the eight areas in every code audit, plus checks written for React Native, Flutter, iOS, and Android.
Payment, AI, database, and email keys compiled into the app, where anyone can pull them out, and paid APIs the app calls directly instead of through your server.
Sign-in tokens in plain storage instead of the Keychain or Keystore, local databases left unencrypted, and data and push tokens that stay behind after logout.
Links that open screens or take actions without checks, sign-in redirects another app can intercept, and WebViews that load untrusted pages with a bridge into the app.
Cleartext traffic and security exceptions, exported Android components, backups and debug flags, permissions nothing uses, and logging left in release builds.
Long lists that render everything, work that blocks the UI, oversized images and slow startup, and crash reporting that can’t tell you where a crash happened.
Target SDK and Xcode requirements, privacy manifests and data labels, in-app account deletion, signing keys and store account ownership, and a way to force an update.
Every audit runs scanners like gitleaks, osv-scanner, and Semgrep against your code, but few scanners understand mobile app configuration, and the best ones need a built app. The findings that hurt most in mobile apps are usually ones a scanner can’t see:
Those come from reading the code, and from building and shipping mobile apps of our own.
Three levels, each a fixed fee. Essentials covers the most important mobile checks; Standard and Comprehensive cover all of them. See everything every audit includes.
A fast health check
$1,000 fixed fee
Best for: Answering "is this codebase OK?" before you buy, hire, or launch.
A thorough review
$1,500 fixed fee
Best for: An inherited codebase, a pre-launch review, or before hiring a team.
Everything in Essentials, plus:
Due diligence depth
$2,500 fixed fee
Best for: Acquisitions and technical due diligence, compliance preparation, or after an incident.
Everything in Standard, plus:
React Native maintains only its latest three minor releases, Expo ships about three SDKs a year, and Flutter fixes only its current stable release. Every mobile audit checks your framework and SDK versions against the official support policies, and your native libraries against the versions you’re on.
The stores force upgrades too: Google Play now requires new apps and updates to target Android 16 (API level 36), and Apple requires builds from Xcode 26. If you’re behind, the report lays out the upgrade step by step, and Standard and Comprehensive also list the libraries that stand in the way. When you’re ready, we can do the upgrade too.
Checked November 13, 2026 against the Expo SDK versions.
Follows federal and state grant opportunities and tells you on your phone about new matches, moved deadlines and amended notices, with AI summaries of long notices. Android and iOS apps, with a web admin area.
The same fixed fees as every audit: $1,000 for Essentials, $1,500 for Standard, and $2,500 for Comprehensive. Compare the levels. Hire us for hourly development within 30 days of your report and up to $1,000 of the fee comes off your first invoice.
Yes. React Native and Expo, Flutter, native iOS in Swift, and native Android in Kotlin each have their own checklist, covering the same ground: secrets, storage, deep links, WebViews, performance, dependencies, and store requirements.
If it’s in the code you share, yes. Most mobile apps talk to an API, and many of the worst problems live there, so we can review both together. The back end gets the checks for its own stack, like Rails, Node.js, or Django.
No, but it helps. The source code settles most checks. A release build (APK, AAB, or IPA) shows what really ships, like keys bundled into the app. We only inspect it as data and never install or run it on our own machines.
It checks the requirements that most often block a release: target SDK and Xcode versions, privacy manifests, data safety and privacy labels, in-app account deletion, and permissions the app declares but doesn’t use.
Yes. We can work alongside your team or take it on ourselves, and the audit credit applies.
Tell us about your mobile app and we'll recommend the level that fits.
