Form correction you feel, not watch.

Tempo apps count reps. Posture apps nudge you when you slouch. FlexCue is the missing piece: live, full-body alignment correction — a hip that's rotated, a knee caving in, a spine out of plane — cued the moment it happens, entirely through directional, graded vibration.

Prop your phone

Camera-based body tracking (ARKit + LiDAR, Vision fallback) reads your position spatially.

Wear your Watch + AirPods

Limb and head orientation keep flowing even when the camera can't see you.

Fused, not toggled

FlexCue blends both sources live, leaning on whichever is more confident moment to moment.

Cued by touch alone

Deviation maps to haptic intensity and rhythm — soft and rare in the zone, firmer the further off you drift.

One pose, one movement, one working slice at a time — starting with Warrior II and a bodyweight squat. Yoga holds and PT reps share the same engine underneath: FlexCue watches your joint angles against a target, and tells you where you've drifted before you'd ever notice on your own.

No screen required, on purpose

You don't hold your phone during a session, and you don't glance at a screen mid-pose. FlexCue is built to be used eyes-closed — the phone props on a mat or shelf as a camera, and every correction reaches you through touch: firmer and more frequent the further you drift, quieting to a rare, soft confirmation when you're holding the line.

A coaching tool, not a medical device

FlexCue is a wellness and coaching aid for yoga and general PT-style movement practice. It is not a certified physical therapy device and isn't a substitute for guidance from a qualified instructor, physical therapist, or physician — see Terms for the full disclaimer.
