Effortless logging, smart suggestions.
Zoku remembers your favourites. Add a meal in two taps, adjust portions with a slider.
Sleep & Recovery
Wake up knowing
how to train today.
One number tells you if you're recovered or wrecked. Paired with your sleep stages, HRV and resting heart rate, Zoku turns gut-feel into data-backed confidence.
Recovery score, every morning
A clear 0–100 score that factors HRV, RHR and sleep quality into one decision.
Stages that actually matter
REM, core, deep, awake — visualised cleanly so you spot patterns over weeks.
Smart sleep window
Zoku learns your chronotype and nudges you to bed when your body expects it.
Activity & Strain
Every rep,
every run,
one number.
Track strain across lifts, rides, runs and yoga. Zoku reads your heart rate zones and gives you a single score to aim for — or rest from.
