Works with everything you wear

Or with nothing at all.

Sleep, HRV, resting heart rate. Read from whatever you already use, and adapt today's session to how you're actually recovering.

The system

Three words.
Infinite adaptability.

Progress

Recovery is strong. Load increases, volume expands. The engine finds your edge and moves you forward.

Hold

Mixed signals, travel approaching, or a niggle flaring. Baseline maintained — nothing gained, nothing lost.

Deload

HRV down, sleep short, or you said Bad. Volume drops, intensity moderates. Protect the baseline, come back stronger.

How it works

Five gym decisions, made for you — every day.

01

It reads your recovery

Sleep, HRV and resting HR from any band — or a one-tap Good / Okay / Bad if you don't wear one.

02

It writes today's session

Warm-up, three to five lifts with prescribed loads, a short recovery block. One screen. Built for your gym.

03

It adapts as you go

Easy / OK / Hard per lift drives the next session. Report a niggle and your next sessions re-plan instantly.

Pricing

One plan. $9.99/mo

Or $79/year. 7-day free trial. Works with Whoop, Oura & Apple Watch — or no band at all.
