The gap
Built for a clock most people don’t work
MyFitnessPal, Noom and every mainstream tracker quietly assume a 9-to-5. If your life doesn't fit that box, their advice doesn't fit you.
What the 9-to-5 apps assume
Same hours.
Same body.
Every single day.
What your life actually looks like
Nights. Earlies.
Doubles. Cycles.
A clock all your own.
Timing-blind advice
Eat at 8am, train at 6pm, sleep at 11. Great — if your day looks like a spreadsheet. Rotating and night shifts break every assumption these apps are built on.
One-size-fits-none plans
The same generic macros for a night-shift nurse, a marathoner and a woman mid-cycle. No schedule awareness, no cycle adaptation — a template that fits no one.
Fragmented across 4–5 apps
One app to log food, another for workouts, a watch app, a recipe app, a coach elsewhere. Your fitness life is scattered and nothing talks to anything.
Punished for working nights
Log a 2am meal and mainstream trackers flag you as "off plan." Your body is doing exactly what it should — the app just never learned your clock exists.
shift workers the mainstream apps forget.
Nurses, paramedics, logistics and hospitality crews — plus everyone syncing training to a cycle instead of a calendar. Zeitra is built for the people the 9-to-5 apps quietly designed around.

The science
Chrono-nutrition, built around your real clock
Circadian science shows that WHEN you eat, train and sleep changes metabolism, recovery and sleep quality — especially when your schedule fights your body clock.
Your day24Htimed to your rota
Sleep
Wake
Fuel
Cut-off
Train
Most apps hand everyone the same 9-to-5 plan. Zeitra operationalizes chrono-nutrition around YOUR rota — so your meals, caffeine, training and wind-down land at the right hour for the day you're actually working.
When you eat is a signal
Meal timing sets your metabolic clock. Eat against your body clock and the same food lands differently — Zeitra times it to your shift, not a textbook 9-to-5.
Train with your rhythm
Strength, output and recovery all swing across the day. Zeitra schedules training into the windows your real rota actually leaves open.
Caffeine & sleep, on a cut-off
Late caffeine and mistimed light wreck the sleep you need most after a night shift. Zeitra sets your cut-offs and wind-down around when you clock off.
- Shift workers worldwide
- Timing points aligned daily
- Textbook 9-to-5s assumed

From the floor
Built for the shifts the 9-to-5 apps forget
Illustrative stories from the people mainstream apps leave out — nurses, paramedics, athletes and everyone whose clock doesn't fit a textbook.
Every other app assumed I ate lunch at noon. Zeitra finally gets that "noon" for me is 3am. My energy on nights is a different world now.
Night-shift ICU nurse4-on / 4-off rotationTraining synced to my cycle plus feeding a newborn at odd hours — this is the first app that treats my clock as the real one instead of fighting it.
Marathoner + new mumCycle-aware trainingMy roster changes every week and the timing engine just rolls with it. Ria re-plans my meals and caffeine around the next block without me touching anything.
Rotating-roster paramedicVariable shift patternI snap a photo of the plate, my old fitness band pairs over Bluetooth, and it all lands in one place. Five apps down to one.

Consistency
Your rhythm, tracked
Irregular shifts make consistency feel impossible. Zeitra turns every logged meal, workout and wind-down into a streak that adapts to the day you're actually working — so the rhythm builds even when your schedule doesn't.

Streaks that survive night shifts
A rotating rota breaks most habit trackers. Zeitra counts a day as done when you hit YOUR plan for that shift — so a 3am dinner still keeps the streak alive.
