# Sleep and energy — an honest read on what last night gives you

Reps turns your Apple Watch's sleep data into an energy budget for the day — a plain answer to "how much do I actually have today," built from your own sleep, not a guess.

## An honest energy read

Reps' energy gauge is built to tell you the truth on mornings you didn't really sleep, rather than defaulting to an optimistic number because your activity was low. If your sleep was short or broken, the energy read reflects that before you commit to a hard training session — not after you're already mid-workout and running low.

## Feeds into the Readiness Score

Sleep isn't tracked as an isolated stat in Reps — it's one of the core inputs to the daily Readiness Score alongside HRV and training load, and it factors into peak, good, recovery, and avoid training windows for the day.

## Why "honest" matters here

A lot of fitness trackers default toward reassuring numbers. Reps is built to do the opposite when the data calls for it: if the sleep behind an energy read is thin, the app says so, rather than smoothing it into a falsely comfortable score.

## Where it shows up

The energy read sits alongside the Readiness Score and the day's peak/good/recovery/avoid training windows, so you're looking at one consistent picture — how recovered you are, how much energy you're carrying, and when today is best used — rather than three disconnected numbers pulled from different screens.

## No extra hardware

Sleep and energy tracking use the sleep data your Apple Watch already collects through Apple Health — there's no separate sleep sensor, mat, or ring required.

## What it isn't

The energy budget and sleep read are training-recovery tools, not a sleep-disorder diagnostic. Reps doesn't diagnose sleep conditions or make medical claims about sleep quality.
