Zepraug

how it works

What Zepraug does with your data, feature by feature.

For each of the six features: what you see on screen, what the app computes behind it, and the exact meaning of the words used.

health data

Reading your signals

What you see

One number per signal — average night, resting heart rate, steps, weight — and under each number a plain sentence saying whether it is high, low, or in line with your habit.

What the app does
  1. 1It asks Apple Health or Health Connect for the categories you allow, and nothing more.
  2. 2It computes your median over the chosen window, then places today’s value against it.
  3. 3It counts the days actually measured. If four nights are missing out of thirty, it says so instead of smoothing the gap.
  4. 4It picks the matching sentence and shows it behind a sage dot.
The Health tab of the app: average night, daily steps and resting heart rate, each with its sentence.

Reading this card

The sage dot
announces a reading: a sentence written by the app, not raw data.
The empty circles
are nights without a measurement. No value is invented in their place.
The size of the dots
carries the value: the bigger the dot, the longer the night.

zepo

Asking a question

What you see

A conversation. You type, dictate or photograph; Zepo answers in text and can attach a card — a lighter session, a meal, a programme — that you apply in one gesture.

What the app does
  1. 1It gathers the context the question needs: your recent nights, your resting heart rate, your training log, today’s meals.
  2. 2It sends the question with that context, without attaching your identity.
  3. 3It shows the answer and, underneath, the data it leans on — you can check.
  4. 4If the answer contains an action, that action becomes an applicable card, not an instruction to copy out.
A conversation with Zepo: the answer cites your nights and resting heart rate before offering a lighter session.

What leaves the device

The question and the numbers it requires
and nothing more. Your full history stays on the device.

training

Logging a set

What you see

The exercise, its prescription, and the sets already logged. Below them, two dials — reps and load — then an effort notch, and the button that confirms.

What the app does
  1. 1It pre-fills the dials with what you did last time on this exercise.
  2. 2You confirm; the set is timestamped and joins your history.
  3. 3The rest timer starts at the duration set for this exercise.
  4. 4On the next set it applies the programme’s rule: if you held the top of the range at the right effort, it suggests the load above.
Logging a session: the exercise, the prescription, the sets already done with their load and effort.

The effort notches

Easy
you had several reps left in reserve.
Moderate
two or three reps in reserve.
Hard
one rep in reserve, the bar slows down.
To failure
the last rep did not go up.

nutrition

Filling your plate

What you see

A ring for the calories left, three bars for the macros, and the day’s list of meals. At the bottom, a single button to add.

What the app does
  1. 1You choose the input: a photo of the plate, two dictated words, free text, or a barcode.
  2. 2It recognises the foods and suggests portions, which you correct in one gesture.
  3. 3It adds up the macros and recomputes what is left of the day.
  4. 4It compares that with the day’s need, computed from your weight and your sessions, and writes what you are missing.
Today’s plate: the ring of calories left, Zepo’s sentence about protein and the four meals of the day.

What the estimate is worth

A photo
gives an order of magnitude, useful for a weekly trend.
A barcode
reads the values off the packet: it is the precise route when it exists.

exercises

Finding a movement

What you see

The body areas, each with its number of exercises and a representative plate. Inside an area, the full list, filterable by equipment.

What the app does
  1. 1Every exercise carries a drawn plate: starting position, path, target muscle.
  2. 2The filing follows the movement, not the name: a pull-up and a lat pulldown live in the same place.
  3. 3From the sheet you can start a free set or swap the exercise in today’s session.
The exercise library: illustrated cards sorted by muscle group, with the number of exercises in each.

How it is filed

By movement
and not by exercise name: the gesture decides the place.
Filterable by equipment
so you only see what you have to hand.

programmes

Following a programme

What you see

The active programme at the top, its weeks as pills, and the days as tabs. Under the chosen day, the progression rule and the session’s progress.

What the app does
  1. 1You take a programme from the library — gym, home, outdoor — or have Zepo generate one from your constraints.
  2. 2The weeks are periodised: volume and intensity rise, then a deload week brings them down.
  3. 3Each day carries its progression rule, and that rule decides when the load goes up.
  4. 4An archived programme keeps its whole history: reactivating it picks up where you left off.
Programmes: the active one with its week and frequency, the archived ones, and the library.

The progression rules

Double progression
you first raise the reps within the range, then the load once the top is reached.
Load progression
the reps stay fixed; the load goes up as soon as the effort allows.
Deload week
reduced volume for a week to let fatigue come down.

glossary

The words used in the app

Reading
The sentence the app writes under a number. It places the value against your habit, and nothing else.
Your norm
Your own median over the window shown. Never a population average.
Measured day
A day where the data actually exists. The others stay empty, and the app says so.
Perceived effort
Your reading of the set, in four notches: easy, moderate, hard, to failure.
Double progression
Raise the reps to the top of the range, then raise the load.
Periodisation
How the weeks are organised: accumulation, then a deload week.
Deload week
A week at reduced volume, planned into the programme, to let fatigue come down.
Guided / free session
Guided: the app suggests the programme’s order and loads. Free: you log whatever you want.
Local storage
Your data lives in the app, on your device. Uninstalling the app erases it.

You know how it works. All that is left is logging the first set.
