Deep scan of your app screenshots to detect missing "Delete Account" buttons (5.1.1) or placeholder content.

Guideline Grounding

Strict comparison with the latest App Review Guidelines PDF to eliminate AI hallucinations.

FAQs

Frequently Asked Questions

Everything you need to know about our tools and the studio.

Is my app data safe?

Yes. All uploaded screenshots are physically destroyed from our servers immediately after the report is generated. We never use your data for model training.

How accurate is the AI?

We use Gemini 1.5 Pro with "Doc-Grounded" reasoning. This means the AI must find a specific clause in the App Store Review Guidelines to justify its verdict, minimizing hallucinations.

What browsers are supported?

AppPreflight is optimized for modern browsers (Chrome, Edge, Safari). Our reports use SSE for a smooth real-time experience.
