Regulatory Information
How It Works

A simple loop: measure, interpret, remind, retrain.

The Puck measures real muscle activity, shows whether the muscle you care about is truly engaged, and helps you train stronger habits over time.

01
Download the app

Available soon on iPhone and Android. Download the Longevity Quantified app first, then work through the steps below.

02
The Puck
The Puck

The reusable electronic module houses the core technology and features three muscle-sensor (EMG) electrode snaps that connect to the electrode patch.

03
The Electrode Patch
The Electrode Patch

A hypoallergenic adhesive patch with three distinct conductive gel zones. It positions the electrodes correctly and keeps them from touching, so every reading stays clean and reliable.

04
Peel the liner
Peel the liner

Remove the backing liner from the electrode patch.

05
Snap on the Puck
Snap on the Puck

Align the Puck with the three snaps on the patch and press to snap it securely - a stable mechanical and electrical connection for accurate EMG reading.

06
Place it on your body
Place it on your body

Position the patch so the conductive zones sit flush against your skin, over any muscle you want to track. Apply gentle pressure for full skin contact. (For posture tracking, place it flat between your shoulder blade and spine, over the upper trapezius and rhomboid muscles.)

07
Open the app and connect
Open the app and connect

Launch the Longevity Quantified app to connect with the Puck. It instantly begins reading EMG and motion data and shows your live muscle activation.

08
Watch your feedback
State A · Slouching
State A · Slouching
Signals low - not actively supported
State B · Good Posture
State B · Good Posture
Signals up - muscles actively engaged

Using posture tracking as the example: the app shows two sides of the same moment - when you slouch, the on-screen feedback slouches and the signals stay low; when you sit tall and engage your own muscles, it switches upright and the signals rise.

09
Gentle reminders, on your terms
Gentle reminders, on your terms

You choose the reminder delay. If poor form lasts longer than that, the Puck gives a calm vibration cue right where it is placed. Turn vibrations on or off anytime in the app.
