HapiFlip

HapiFlip puts Linux and terminal cheat sheets on your Apple Watch — so the command is on your wrist when your brain blanks. Raise your watch, open a module, and flip cards with the Digital Crown. The front shows the command; flip for what it means, who made it, and where to read more. Long-press to hear it spoken while you type. Built for developers, SREs, and anyone who lives in a shell — on-call, SSH, Docker, Kubernetes, or everyday git panic. WHAT’S INCLUDED (15 modules, 230+ commands) • Daily queue — five rotating commands each day • Git — status, stash, reset, rebase, and more • Permissions — chmod, chown, sudo • Files — find, grep, tar, disk • Network — curl, ssh, DNS, ports • Docker — ps, logs, compose • Process — ps, kill, systemd • On-call — uptime, memory, triage • VPS → Web — nginx, firewall, HTTPS path • Packages — apt, dnf • Text — sed, awk, jq • SSH & Keys — keys, tunnels, config • Kubernetes — pods, logs, apply • Data CLIs — psql, redis, sqlite • Hermes & OpenClaw — agent CLIs WHY ON THE WATCH • Offline — no account required for the core library • Glanceable — raise wrist, get the command, get back to work • Crown-first — flip through a deck without unlocking your phone WHO IT’S FOR Builders who already know the tools but forget exact flags under pressure. Not a full Linux course — a wrist reference you actually use. Apple Watch required (watch-only app). Feedback: hapi.chair@gmail.com
