Your biometrics and data connected to your work.

Athletes have trained this way for decades. It is time professionals caught up.

01
Measure
Sleep, heart rate variability and resting heart rate from the device you already wear, plus deep work sessions and how the day actually went.
02
Analyze
Insights you can act on. Which days you think best, what a short night actually costs you, where your judgment starts to drift.
03
Adapt
Learn what to change. Which day of the week is genuinely your best, which habits move the number, and what to stop doing on the days that are not.
04
Perform
Become better at what you do, with a record that proves it instead of a feeling that suggests it.
01Measure

Both sides of the ledger.

The wearable handles your biology. Thirty seconds a day handles the rest.

Knowing the number is half of it.

The other half is building the week around what it tells you.

Deep Work

See which categories your Strong days go to, then start protecting them for the work that actually compounds.

Reflection, in hindsight

Read last month’s answers back with the score you held that day sitting next to each one.

Insights

Day-of-week trends, streaks and sleep correlations, computed from your own history.

Then take it to the team.

Inside the app your name sits beside your own data point. Inside a team, everything is aggregated.

06Questions

A 0–100 number calculated each morning from sleep, heart rate variability and resting heart rate. Each signal is compared to your own 60-day rolling baseline, because a 42ms HRV is unremarkable for one person and a warning sign for another.

Deep work sessions and their categories, decisions with a confidence rating and an outcome, an evening reflection, and a ten-second morning check-in. The score is one column; what you actually produced is the other. The product is the overlap.

Every personal feature, with no subscription. Pro unlocks one thing: creating a team and seeing aggregated team readiness.

If you already wear your device, 15 days of history import the moment you connect, so your score is ready the same day. Starting with a brand new device, the Today tab shows a calibration state until a baseline exists, which takes about 3 days of readings. Every score is measured against a 60-day rolling window, so it keeps sharpening after that.

The weights redistribute rather than guess. A device that reports sleep but no heart rate variability gives a score built entirely from sleep. If one heart signal is missing, sleep carries two thirds and the remaining signal one third.

Reflections, decisions and deep work notes are encrypted with AES-256 on your iPhone before upload. The keys live only in your Keychain, so we cannot read them. Everything else is stored in the EU. Nothing is ever sold, and one tap in Settings deletes everything.

No. Team features show aggregated readiness only. If team features are used in an employment context, the team creator is responsible for the employment law, data protection and works council requirements that apply in their country.

Measure. Analyze. Adapt. Perform.
