Can I really tap the pads with my chin while holding a plank?

Yes. The 5 sewn copper-nickel conductive-fabric pads respond to a chin, knuckle, or opposite wrist, so with your forearm planted you can trigger the timer without either hand leaving the floor.

Is the display readable while my face is near the floor?

The 8×32 matrix spans the length of your forearm and the bold digits face up and inward, sitting roughly 8 inches from your eyes in a standard forearm plank—well within near vision without lifting your head.

Can I add my own hold times or exercises?

Yes. Open the Sleeve Studio app and edit the plank, wall_sit, and dead_hang values or add new named presets in plain English, then send the mode to the sleeve over Bluetooth in about 30 seconds.

Plank, Wall-Sit and Isometric Hold Floor Sightline Forearm Timer

Drop into a forearm plank and the 8×32 RGB LED matrix sits inches from your eyes, counting a bold 01:00 down to 00:00 along your forearm; tap the 5 conductive-fabric pads with your chin or knuckle to start, rest, or open a new set — no sweaty phone, no wrist twist to read a watch ($199).

Countdown where you already look: The matrix shows a bold timer in the plank sightline so you never break form to check a phone.
Chin-tap control: Start, rest, log, and end sets with a nudge of the chin or knuckle instead of a reach.
Ships as 1 of 50 modes: Pre-loaded as Isometric Countdown; set your own holds in the Sleeve Studio app.

Why Sweaty Phones and Wrist-Watch Twists Break Isometric Holds

Twisting a wrist breaks the hold: Glancing at a watch unloads the exact core or shoulder you are trying to hold.
Phones can’t be grabbed mid-plank: Picking one up means dropping form; the timer is already where your eyes point.
Peer-reviewed textile roots, shipping hardware: The Oct 2026 NUS Nature paper coined “garment GUI” with a lab-only woven pixel fibre (not for sale); our shipping $199 sleeve uses 5 sewn conductive-fabric pads and a removable 8×32 LED pod.
