Hi everyone 👋
As a network engineer and indie iOS developer, I couldn’t find a lightweight mobile tool that fully supports IPv4/IPv6 dual-stack diagnostics — so I built NetToolbox -All-In-One Utility for engineers, DevOps, and developers.
Here are its core features that solve real mobile networking pain points:
- One-Click Full Diagnostics: Integrates ping, traceroute, and multi-type DNS queries (A/AAAA/CNAME) — no need to switch between apps
- IPv4/IPv6 Dual-Stack Support: Seamlessly works in IPv6-only networks, with the ability to test connectivity differences between dual-stack environments
- LAN Device Scanning: Quickly identifies all devices on the same network segment and checks port availability
- Offline Functionality: Diagnostic logic is stored locally, enabling LAN troubleshooting without an internet connection
- Lightweight Design: 5MB install size, no storage bloat, and low power consumption during operation
- Dark Mode Support: Tailored for developers who work late at night
During development, I leveraged Apple Intelligence alongside Claude Code and Gemini 3 to accelerate the process, optimize iOS native networking stack adaptation and local storage logic, and significantly boost development efficiency.
I’d love to hear from the community:
- What must-have features are missing from mobile network diagnostic tools?
- Do you have experience optimizing iOS workflows with Apple Intelligence?

Feedback is highly appreciated — I’ll keep iterating to make it better! 🚀
