Edge

What's new:

Attempt at many-device support — a bunch of new bands/watches/rings can pair now, sync depth varies by device.

WHOOP MG heart screener — capture + history for the ECG reading, hook into AI coach analysis.

Alarms that actually work — weekly schedule, safety notification if it doesn't latch, smart wake window.

Openstrap Edge:

An app that makes your wearable useful without its subscription. Pairs over Bluetooth, computes everything on your phone, iOS and Android. WHOOP 4/5/MG get full support today; see Supports for what else it talks to.

Not affiliated with WHOOP. Not a clone of their app or their scores — see below.

As featured in:

"The goal of the so-called OpenStrap project is not to re-create the WHOOP app. Rather, the algorithms and processing methods are developed from scratch, based on public research… The health data collected from the watch never leaves the phone.".
