Crane uses on-device AI to monitor your posture during long gaming sessions and reminds you to stretch between matches — never during gameplay. No cloud, no lag, no data collected.
Competitive and casual gamers alike spend hours locked into high-intensity postures — leaning forward toward the screen, shoulders rounded, wrists flexed at extreme angles. The physical cost is well documented in esports medicine research:
"Gaming neck" — the forward head posture caused by leaning toward a monitor during intense gameplay — puts severe strain on the cervical spine. Every inch your head moves forward adds roughly 10 pounds of effective weight on your neck muscles. Over a 4-hour session, this leads to muscle fatigue, tension headaches, and the chronic stiffness that many gamers accept as normal.
Wrist injuries are equally common. Rapid, repetitive mouse and keyboard inputs sustained over hours create the conditions for carpal tunnel syndrome, tendinitis, and De Quervain's tenosynovitis. Professional esports players have had careers cut short by wrist injuries that began as minor discomfort during long practice sessions.
The core problem with existing break reminders is timing. A timer that fires mid-match is worse than useless — it is a distraction that costs you the round. Gamers need reminders that respect the rhythm of their play: between matches, between rounds, during queue times.
Crane was built with the understanding that gaming has a natural rhythm of high-intensity play followed by brief downtime. Every feature is designed to work with that rhythm, not against it.
Crane uses your webcam and TensorFlow.js to track your head position and shoulder alignment in real time. When you start slouching toward the screen — the classic competitive gaming lean — Crane sends a subtle overlay notification. It never steals focus, never pauses your game, and never interferes with fullscreen applications. You see the nudge in your peripheral vision and correct when you are ready.
The Match Break profile uses 45-minute cycles designed to align with typical gaming sessions. When a cycle ends, you get a gentle reminder to stretch. If you are mid-match, ignore it — Crane will not escalate or nag. The reminder is there for the natural pause between games, when you are waiting in queue or reviewing stats.
Crane includes stretch activities specifically targeting the wrists, forearms, and hands — the most vulnerable areas for gamers. Simple 30-second wrist extension and flexion stretches between matches can significantly reduce the cumulative strain from rapid mouse and keyboard inputs.
Crane's AI runs on your CPU using lightweight pose estimation. It uses minimal resources — typically less than 2% CPU — and does not interfere with your GPU, frame rate, or game performance. There is no cloud processing, no network traffic, and no background uploads.
The Match Break profile is designed for gamers who play in sessions of 2 to 6 hours. Its 45-minute cycle provides a natural checkpoint without disrupting gameplay:
This cycle is intentionally simple. Thirty minutes of seated play followed by a 15-minute recovery window with standing, stretching, and walking. The recovery interval is not a hard break — it is a suggestion timed to coincide with natural pauses between matches.
Professional esports organizations are increasingly incorporating structured break protocols into training schedules. The Match Break profile brings that same discipline to casual and competitive gamers alike.
If you stream for 3 to 6 hours at a time, the Stream Safe profile offers a 60-minute cycle with longer seated blocks and recovery intervals designed for on-camera work. It pairs well with Match Break — use Match Break for competitive play, Stream Safe for broadcast sessions.
Crane processes everything locally on your machine. Your webcam feed is analyzed frame-by-frame in memory and immediately discarded. No screenshots, no recordings, no data ever leaves your PC. The AI model runs on your CPU through TensorFlow.js — your GPU stays fully available for your game.
There is no account to create, no subscription to manage, and no login required. Install it, configure your profile, and forget about it until you see the next stretch reminder between rounds.
