What it is

Small input, big output

Without data NEXT8 couldn’t calculate anything. That’s why the log is deliberately fast: sliders and taps, no typing. In the morning you say how you slept and how you feel. In the evening you add workouts and how demanding the day was.

How it works

The logical day ends at 3 a.m.

If you log after midnight, you’re still writing into yesterday — the app knows this and doesn’t switch the date needlessly. If you have a smartwatch, sleep and heart rate pre-fill from health data, so you just confirm.

What it’s for

Why it makes sense

It feeds the NEXT8 Index

Every input has its weight in the resulting score.

It builds history

After a few weeks you see patterns you’d otherwise miss.

The coach sees a summary

If you’re on a team, the staff can tell who’s tired.

In the app

What your day looks like

Morning

Sleep, energy, stress, pain.

During the day

The app waits, the day boundary is at 3:00.

Evening

Workouts, RPE and how demanding it was.

Start tomorrow morning. Two minutes is enough.

Download NEXT8 for free and log your first morning — the rest of the app kicks off on its own.
