The Keystone App Audit
A senior engineer goes through your app for 1-2 weeks. You get a scored report, a prioritized fix plan, and straight answers. €790, fixed.
Sound familiar?
“Every release breaks something new.” “The app got slower and nobody knows why.” “Our developer left. What did he leave behind?” “The agency says it is fine. I want a second opinion.”
If any of these sound like your app, the audit answers them with evidence.
The 5 lenses
Architecture and maintainability. Is the structure helping you or fighting you? How expensive will change be next year?
Code quality and tech debt. Where the debt is concentrated, what it costs you, and what is worth paying down.
Performance. Slow launches, janky scrolling, memory pressure: measured on real devices, located, explained.
Stability. Why it crashes, how to see crashes coming, and how to stop shipping them.
Delivery pipeline. Tests, CI/CD, release process: how fast and safely you can ship.
What you get
A scored report written in plain language, with the evidence behind every finding.
A prioritized fix plan: quick wins your team can do this sprint, then the strategic work, each with an effort estimate.
2 follow-up calls: one to walk through the report, one 2 to 4 weeks later to check on progress.
No lock-in. The report is written so your team can execute it. If you want it executed for you, that is what App Rescue is for.

What I need from you
Read access to the repository, and 30 minutes with whoever knows the app best. NDA? Fine. Send yours or use mine.
Questions you might have
What if the code is very old or partly Objective-C? I have worked in Swift and Objective-C codebases since 2017. Old code is normal. It is usually the reason an audit is needed.
Do you only audit iOS apps? iOS is my core and the biggest part of my work. I also audit Flutter, React Native, and native Android apps, and the backend behind the app.
What if you find nothing serious? Then you get something rare: a senior engineer confirming your app is in good shape, with evidence. That is worth having before your next investment or big feature.
1-2 weeks from when? From the moment I get repository access. You get the report on a call, not just as an email attachment.
