Chrono-nutrition for shift workers

Your body isn't on a 9-to-5. Your nutrition shouldn't be either.

Zeitra times your meals, workouts, caffeine and sleep to your real shift — built for the 1.8 billion nurses, drivers, factory and ER workers the other apps ignore.

The same meal at 2 PM and 2 AM isn't the same meal.

Eating against your body clock changes how you process food — that's why standard meal planners quietly fail shift workers. The higher health risks aren't a willpower problem. They're a timing problem.

Zeitra is the only app that schedules everything around your sleep window instead of a sunrise you never see.

2 PMDaytime metabolism — insulin response is primed, fuel is used well.
2 AMCircadian low — the same carbs spike higher and store more. Timing matters.
How Zeitra works

Built around your shift, not the sun

Six things every other fitness app gets wrong for people who work nights.

🕐

Reverse meal timing

Pre-shift, mid-shift, recovery and sleep-prep meals — all scheduled around your sleep window, timed by chrono-nutrition science.

🧠

Meet Ria, your 3-layer AI

Caffeine timing that works

Real cut-off windows for night shifts — so you're not lying awake at 8 AM after a coffee at 4 AM.
