Overnight
It starts with the night you actually had.
Deep, core and REM read straight off your watch and set against your own baseline. Sleep is the first thing to slip after forty and the first thing worth defending.
Not a fitness app. It reads your watch overnight, then decides the aerobic work, the lifting and the food that keep the next twenty years worth having.
From £4.99 a month · no minimum term


What happens overnight
Three things happen while you are asleep. None of them need you.
7h 48m asleep · HRV 42ms · resting heart rate 50
Set against your own baseline, not an average for a fifty year old.
One session, four meals, two supplements. One day.
Aerobic work, lifting and food written together, not by four apps.
Dotted is what it planned. Solid is what it did.
Recovery came back slow, so this week eased off on its own.
One day, start to finish
Overnight
Deep, core and REM read straight off your watch and set against your own baseline. Sleep is the first thing to slip after forty and the first thing worth defending.
06:41
Readiness is scored overnight. Zone two instead of intervals, protein up, magnesium moved to nine, all of it done by the time you pick the phone up.
09:00
A Cytoplan pack matched to you, posted monthly, each one timed to the meal it belongs with. The app watches the weeks that follow, so anything not earning its place gets dropped.
Training
Two or three lifting sessions a week, progressed slowly enough to still be doing them at sixty. Point the camera at yourself and it counts the reps and checks the depth.
Meals
A week built from what you already like, with the protein held high enough to defend the muscle you have. Swap anything in a tap and the rest of the week moves.
19:00
Every meal stepped out with a timer on each stage and the exact weights, on the phone or read out on the watch.

7h 48m
45 minutes over your usual, and a full run of deep.
1h 28m
The stage that thins out with age. Yours held.
42ms
Inside your normal range for eight nights running.
50bpm
Four lower than the summer, without trying to be.

Good. Enough for the zone two, not for the intervals.
2,297kcal
Porridge at ten, with the protein already counted.

Above your four-week average, so today comes down.
18
Fourteen years under your real age, and still falling.
21:00
Moved earlier. You are training at seven tomorrow.
One night, nine decisions you did not have to make
Getting started
01
Your goals, the week you actually have, the kit you can get to, the food you will not eat and the joints you work around.
02
Aerobic work, lifting, meals, a shopping list and your two supplements, written together as one plan instead of by four different apps.
03
It syncs overnight. Load, protein and timing have already moved by the time you pick the phone up in the morning.
04
Two Cytoplan supplements, made up for you, posted to your door and re-matched whenever the plan changes.


Eat
A week built from what you already like, with enough protein to hold onto muscle. Swap anything in a tap.
Train
Point the camera at yourself and it counts the reps, checks the depth and times the rest. Slept badly and the volume drops before you arrive.

Set 2 of 3 · chest supported row
0kg10 reps
Depth good · 75 seconds rest
Supplement
Four hundred on the shelf. Eighty would suit you. Nobody can choose between eighty things, so VitaOS picks two and Cytoplan post them.


The number that matters
Built from your watch's own VO2 max, not an estimate from your weight. A fifty two year old with a strong aerobic base can carry a fitness age in the thirties.

Acidophilus Plus
5-HTP PlusFitness age estimates how old your body performs, rather than how old it is. VitaOS calculates it from your estimated VO2 max, resting heart rate and recovery patterns, then tracks it month to month so you can see the direction of travel.
Yes. VO2 max declines with age if nothing is done, but it responds to training at any age. The work that moves it is mostly easy aerobic volume with a small amount of harder effort, and VitaOS schedules both around your recovery.
The broad guidance is 150 minutes of moderate activity a week plus two sessions of resistance training. VitaOS turns that into specific sessions on specific days rather than leaving you to work out where it fits.
No. Muscle responds to resistance training well into later life, and losing muscle is one of the clearest drivers of decline. Starting later means progressing more slowly and paying more attention to recovery, which is what the app manages.
Zone two is steady aerobic work at a pace where you could still hold a conversation. It builds the base that VO2 max sits on top of. Most people benefit from two to four sessions a week.
No, but the plan is much better with one. The watch is what lets the app read your night and decide your day before you are awake.
The app is £4.99 a month. £44.99 a month adds a supplement pack matched to you and posted monthly. No minimum term, cancel from inside the app.
Wear the watch to bed. Tomorrow already has a plan on it, and the first pack is already on its way.
