The Range Session Problem

01
Hitting 100 balls without knowing what you're reinforcing.
02
Stopping practice to manually review and scrub footage.
03
Expensive lessons that you can't take to every range session.

Built for real practice

On-device first

Motion detection and keyframe capture run locally. You can get value even with zero service.

Cloud-level cue quality

Pro unlocks the model that’s best at turning swing patterns into one clear cue you can actually execute.

Quality gates

Arc tells you if your lighting or camera angle needs a fix—before you waste a bucket.

Designed for momentum

No scrubbing. No editing. Each swing becomes a coaching moment inside the session.

FAQ

How does Arc coach in real time?

Arc tracks key swing moments and delivers one clear cue you can act on between swings.

Is it iPhone only?

Yes, Arc is currently optimized for iOS to leverage its Neural Engine.

What happens to my video?

Arc is designed to minimize data. On-device processing handles detection and keyframe capture. You control what you keep and can delete anytime.

Do I need a tripod?

A simple bag mount or tripod is recommended for best angles, but Arc can work without one if you’re stable.
