Changelog

Unforgeable licensing

• Server-signed Pro — your Pro license is now cryptographically signed by our server with a private key that never ships in the app, so it can't be faked and the software can't be pirated by reading the code. SECURITY
• Stable device binding — licenses bind to a stable device ID that survives restarts and updates. IMPROVED

Secure fresh start

• Hardened the app — the local API now binds to localhost only; no vehicle commands are ever reachable over your network. SECURITY
• Rotated all access keys and locked the AI service behind rate limits and usage caps. SECURITY

This is a new secure baseline. Older versions are discontinued — please install this version fresh (a quick reinstall of the latest download). It only takes a minute and puts you on the clean, secure build.

Simple Mode + AI Repair Mode — our biggest step yet

• Simple Mode — a clean, one-tap home built around a single button: Scan My Car. Every professional tool is still one tap away under Advanced. NEW
• AI Repair Mode — after a full scan, the AI examines everything connected to each fault to find the real root cause, then tells you exactly what to do and what not to replace. No more parts-cannon. NEW
• AI now works fully on mobile — AI Mechanic chat, photo diagnosis, and AI Repair Mode all run on your phone through a secure connection. IMPROVED
• Full multi-module scan — one tap reads every module in the vehicle, not just the engine. IMPROVED

ScanFixAI keeps evolving. We improve the app continuously based on real-world use and your feedback — and this is just the beginning.

📱 Coming soon to the Google Play Store as ScanFixAI - Car Diagnostics — the official app by ScanFixAI (scanfixai.com).
Please note: we are not the older “ScanFix AI” currently listed on Google Play. Make sure you install the official ScanFixAI.
