Quality Assurance & App Audits

Find and fix the bugs hiding in your app.

Yonda AppScan scans your web and mobile apps end-to-end — surfacing bugs, performance bottlenecks, security holes, and UX gaps. You get a prioritized report and a dedicated team to fix them, fast.

See what we check
A comprehensive suite

Everything we scan for

One audit covers the full surface of your application — from the code your users never see to the experience they feel every day.

Functional bugs & regressions

Broken flows, edge cases, and features that quietly stopped working after your last release.

Performance & load speed

Slow pages, heavy bundles, memory leaks, and bottlenecks measured against real-world budgets.

Security & vulnerabilities

Injection, auth flaws, exposed secrets, and dependency CVEs, mapped to OWASP risk categories.

Accessibility (WCAG)

Contrast, keyboard navigation, ARIA, and screen-reader support checked against WCAG 2.2.

Code quality & tech debt

Complexity hotspots, dead code, anti-patterns, and the debt that slows your team down.

UX & usability

Confusing flows, friction points, and drop-offs that cost you conversions and retention.

SEO & metadata

Crawlability, structured data, meta tags, and Core Web Vitals that shape your search ranking.

Cross-browser & mobile

Rendering and behavior verified across browsers, devices, and screen sizes your users actually use.

API reliability & integrations

Flaky endpoints, error handling, rate limits, and third-party integrations under real load.

Our toolkit

The tools behind every scan

We pair industry-standard audit tooling with the modern stack we build on — so we can both find the issues and fix them.

How it works

From scan to shipped fix

A clear, fast process — you always know what we found, why it matters, and what we're doing about it.

1

Share your app

Give us a URL, build, or repo. We scope it in a short kickoff call.

2

We scan & analyze

Automated tooling plus hands-on review across all nine categories.

3

Prioritized report

Every issue ranked by severity, with clear, actionable recommendations.

4

Dedicated team fixes

Want it handled? Our engineers fix issues directly in your codebase.

5

Re-test & verify

We re-run the scan to confirm every fix holds before you ship.

Dedicated team, scaled to you

Results as fast as your project allows

We assign a team sized to your app and timeline. The bigger the project, the bigger the pod — so you get results fast either way.
