The fastest way to get from a symptom to the command that fixes it. Type "cannot connect to the network" into the search box. A diagnostic flow opens with ping, ipconfig, nslookup and tracert laid out in the order you actually run them. You don't need to remember the command name. ■ Fully offline All 882 commands live on your device. Server rooms with no signal, air-gapped networks, a customer site with the Wi-Fi down. The moments you most need to look up networking are the moments the network is broken. Nothing is transmitted, ever. ■ 75 troubleshooting flows "PC is slow." "Mail not arriving." "Port already in use." "Clock drift." Enter the symptom and get an ordered set of steps, each with the command to run at that step. Less time guessing where the fault is. ■ Search that forgives Type "ipconfog" and it suggests ipconfig. Search by alias, not just by name. Filter chips narrow results to Linux, Windows, Cisco and the rest in one tap. ■ Spotlight Swipe down on your home screen, type "netstat", jump straight to the entry without opening the app. ■ What's inside · 882 commands across 15 platforms Linux 178, Windows 107, PowerShell 89, Kubernetes 53, macOS 52, Git 52, Cisco 48, Cloud 48, SQL 44, Docker 41, Active Directory 40, Microsoft 365 36, Virtualization 36, FortiGate 31, Yamaha 27 · 75 troubleshooting flows · Worked examples and syntax for every command · Destructive commands clearly flagged ■ Premium (one-time purchase) · All 75 troubleshooting flows (2 free) · Unlimited favorites (10 free) · iCloud sync · Personal notes on any command · Export Not a subscription. Buy once, that's it. ■ Privacy No account. No ads. No tracking. The developer receives none of your data. The app is offline, so there is nothing to send. ■ Languages App interface and symptom search: English, Japanese, Spanish, German, French, Portuguese, Simplified Chinese, Traditional Chinese, Korean. Command explanations and flow text: English and Japanese only. ■ Please note Content is reference material. Run commands at your own discretion and risk, ideally in a test environment and after taking backups. Built by an in-house IT engineer who wanted this on his own phone.
